The United States of America (USA), commonly known as the United States (U.S. or US) or America, is a country mostly located in central North America, between Canada and Mexico. It consists of 50 states, a federal district, five major self-governing territories, and various possessions.[i] At 3.8 million square miles (9.8 million km2), it is the world's third- or fourth-largest country by total area.[e] With a 2019 estimated population of over 328 million,[7] the U.S. is the third most populous country in the world. Americans are a racially and ethnically diverse population that has been shaped through centuries of immigration. The capital is Washington, D.C., and the most populous city is New York City.

Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago,[19] and European colonization began in the 16th century. The United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies led to the American Revolutionary War lasting between 1775 and 1783, leading to independence.[20] Beginning in the late 18th century, the United States vigorously expanded across North America, gradually acquiring new territories,[21] killing and displacing Native Americans, and admitting new states. By 1848, the United States spanned the continent.[21] Slavery was legal in much of the United States until the second half of the 19th century, when the American Civil War led to its abolition.[22][23]

The Spanish–American War and World War I entrenched the U.S. as a world power, a status confirmed by the outcome of World War II. It was the first country to develop nuclear weapons and is the only country to have used them in warfare. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 Apollo 11 mission, the spaceflight that first landed humans on the Moon. The end of the Cold War and collapse of the Soviet Union in 1991 left the United States as the world's sole superpower.[24]

The United States is a federal republic and a representative democracy. It is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States (OAS), NATO, and other international organizations. It is a permanent member of the United Nations Security Council.

A highly developed country, the United States is the world's largest economy and accounts for approximately a quarter of global gross domestic product (GDP).[25] The United States is the world's largest importer and the second-largest exporter of goods, by value.[26][27] Although its population is only 4.3% of the world total,[28] it holds 29.4% of the total wealth in the world, the largest share held by any country.[29] Despite income and wealth disparities, the United States continues to rank very high in measures of socioeconomic performance, including average wage, median income, median wealth, human development, per capita GDP, and worker productivity.[30][31] It is the foremost military power in the world, making up more than a third of global military spending,[32] and is a leading political, cultural, and scientific force internationally.[33]



The first known use of the name "America" dates back to 1507, when it appeared on a world map created by the German cartographer Martin Waldseemüller. On this map, the name applied to South America in honor of the Italian explorer Amerigo Vespucci.[34] After returning from his expeditions, Vespucci first postulated that the West Indies did not represent Asia's eastern limit, as initially thought by Christopher Columbus, but instead were part of an entirely separate landmass thus far unknown to the Europeans.[35] In 1538, the Flemish cartographer Gerardus Mercator used the name "America" on his own world map, applying it to the entire Western Hemisphere.[36]

The first documentary evidence of the phrase "United States of America" dates from a January 2, 1776 letter written by Stephen Moylan, Esq., to Lt. Col. Joseph Reed, George Washington's aide-de-camp and Muster-Master General of the Continental Army. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort.[37][38][39] The first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776.[40]

The second draft of the Articles of Confederation, prepared by John Dickinson and completed no later than June 17, 1776, declared "The name of this Confederation shall be the 'United States of America'".[41] The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be 'The United States of America'".[42] In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence.[41] This draft of the document did not surface until June 21, 1776, and it is unclear whether it was written before or after Dickinson used the term in his June 17 draft of the Articles of Confederation.[41]

The short form "United States" is also standard. Other common forms are the "U.S.," the "USA," and "America." Colloquial names are the "U.S. of A." and, internationally, the "States." "Columbia," a name popular in poetry and songs of the late 18th century, derives its origin from Christopher Columbus; it appears in the name "District of Columbia." Many landmarks and institutions in the Western Hemisphere bear his name, including the country of Colombia.[43]

The phrase "United States" was originally plural, a description of a collection of independent states—e.g., "the United States are"—including in the Thirteenth Amendment to the United States Constitution, ratified in 1865.[44] The singular form—e.g., "the United States is"—became popular after the end of the Civil War. The singular form is now standard; the plural form is retained in the idiom "these United States." The difference is more significant than usage; it is a difference between a collection of states and a unit.[45]

A citizen of the United States is an "American." "United States," "American" and "U.S." refer to the country adjectivally ("American values," "U.S. forces"). In English, the word "American" rarely refers to topics or subjects not directly connected with the United States.[46]


Indigenous peoples and pre-Columbian history

It has been generally accepted that the first inhabitants of North America migrated from Siberia by way of the Bering land bridge and arrived at least 12,000 years ago; however, increasing evidence suggests an even earlier arrival.[19][47][48] After crossing the land bridge, the Paleo-Indians moved southward along the Pacific coast[49] and through an interior ice-free corridor.[50] The Clovis culture, which appeared around 11,000 BC, was initially believed to represent the first wave of human settlement of the Americas.[51][52] It is likely these represent the first of three major waves of migration into North America.[53]

Over time, indigenous cultures in North America grew increasingly complex, and some, such as the pre-Columbian Mississippian culture in the southeast, developed advanced agriculture, grand architecture, and state-level societies.[54] The Mississippian culture flourished in the south from 800 to 1600 AD, extending from the Mexican border down through Florida.[55] Its city state Cahokia is the largest, most complex pre-Columbian archaeological site in the modern-day United States.[56] In the Four Corners region, Ancestral Puebloan culture developed from centuries of agricultural experimentation.[57]

Three UNESCO World Heritage Sites in the United States are credited to the Pueblos: Mesa Verde National Park, Chaco Culture National Historical Park, and Taos Pueblo.[58][59] The earthworks constructed by Native Americans of the Poverty Point culture have also been designated a UNESCO World Heritage site. In the southern Great Lakes region, the Iroquois Confederacy was established at some point between the twelfth and fifteenth centuries.[60] Most prominent along the Atlantic coast were the Algonquian tribes, who practiced hunting and trapping, along with limited cultivation.

Effects on and interaction with native populations

With the progress of European colonization in the territories of the contemporary United States, the Native Americans were often conquered and displaced.[61] The native population of America declined after European arrival for various reasons,[62][63] primarily diseases such as smallpox and measles.[64][65]

Estimating the native population of North America at the time of European contact is difficult.[66][67] Douglas H. Ubelaker of the Smithsonian Institution estimated that there was a population of 92,916 in the south Atlantic states and a population of 473,616 in the Gulf states,[68] but most academics regard this figure as too low.[66] Anthropologist Henry F. Dobyns believed the populations were much higher, suggesting 1,100,000 along the shores of the gulf of Mexico, 2,211,000 people living between Florida and Massachusetts, 5,250,000 in the Mississippi Valley and tributaries and 697,000 people in the Florida peninsula.[66][67]

In the early days of colonization, many European settlers were subject to food shortages, disease, and attacks from Native Americans. Native Americans were also often at war with neighboring tribes and allied with Europeans in their colonial wars. In many cases, however, natives and settlers came to depend on each other. Settlers traded for food and animal pelts; natives for guns, ammunition and other European goods.[69] Natives taught many settlers to cultivate corn, beans, and squash. European missionaries and others felt it was important to "civilize" the Native Americans and urged them to adopt European agricultural techniques and lifestyles.[70][71]

European settlements

With the advancement of European colonization in North America, the Native Americans were often conquered and displaced.[72] The first Europeans to arrive in the contiguous United States were Spanish conquistadors such as Juan Ponce de León, who made his first visit to Florida in 1513. Even earlier, Christopher Columbus landed in Puerto Rico on his 1493 voyage. The Spanish set up the first settlements in Florida and New Mexico such as Saint Augustine[73] and Santa Fe. The French established their own as well along the Mississippi River. Successful English settlement on the eastern coast of North America began with the Virginia Colony in 1607 at Jamestown and with the Pilgrims' Plymouth Colony in 1620. Many settlers were dissenting Christian groups who came seeking religious freedom. The continent's first elected legislative assembly, Virginia's House of Burgesses, was created in 1619. The Mayflower Compact, signed by the Pilgrims before disembarking, and the Fundamental Orders of Connecticut, established precedents for the pattern of representative self-government and constitutionalism that would develop throughout the American colonies.[74][75]

Most settlers in every colony were small farmers, though other industries were formed. Cash crops included tobacco, rice, and wheat. Extraction industries grew up in furs, fishing and lumber. Manufacturers produced rum and ships, and by the late colonial period, Americans were producing one-seventh of the world's iron supply.[76] Cities eventually dotted the coast to support local economies and serve as trade hubs. English colonists were supplemented by waves of Scotch-Irish immigrants and other groups. As coastal land grew more expensive, freed indentured servants claimed lands further west.[77]

A large-scale slave trade with English privateers began.[78] Because of less disease and better food and treatment, the life expectancy of slaves was much higher in North America than further south, leading to a rapid increase in the numbers of slaves.[79][80] Colonial society was largely divided over the religious and moral implications of slavery, and colonies passed acts for and against the practice.[81][82] But by the turn of the 18th century, African slaves were replacing indentured servants for cash crop labor, especially in the South.[83]

With the establishment of the Province of Georgia in 1732, the 13 colonies that would become the United States of America were administered by the British as overseas dependencies.[84] All nonetheless had local governments with elections open to most free men.[85] With extremely high birth rates, low death rates, and steady settlement, the colonial population grew rapidly. Relatively small Native American populations were eclipsed.[86] The Christian revivalist movement of the 1730s and 1740s known as the Great Awakening fueled interest both in religion and in religious liberty.[87]

During the Seven Years' War (known in the United States as the French and Indian War), British forces seized Canada from the French, but the francophone population remained politically isolated from the southern colonies. Excluding the Native Americans, who were being conquered and displaced, the 13 British colonies had a population of over 2.1 million in 1770, about a third that of Britain. Despite continuing, new arrivals, the rate of natural increase was such that by the 1770s only a small minority of Americans had been born overseas.[88] The colonies' distance from Britain had allowed the development of self-government, but their unprecedented success motivated monarchs to periodically seek to reassert royal authority.[89]

In 1774, the Spanish Navy ship Santiago, under Juan Pérez, entered and anchored in an inlet of Nootka Sound, Vancouver Island, in present-day British Columbia. Although the Spanish did not land, natives paddled to the ship to trade furs for abalone shells from California.[90] At the time, the Spanish were able to monopolize the trade between Asia and North America, granting limited licenses to the Portuguese. When the Russians began establishing a growing fur trading system in Alaska, the Spanish began to challenge the Russians, with Pérez's voyage being the first of many to the Pacific Northwest.[91][j]

During his third and final voyage, Captain James Cook became the first European to begin formal contact with Hawaii.[93] Captain Cook's last voyage included sailing along the coast of North America and Alaska searching for a Northwest Passage for approximately nine months.[94]

Independence and expansion (1776–1865)

The American Revolutionary War was the first successful colonial war of independence against a European power. Americans had developed an ideology of "republicanism" asserting that government rested on the will of the people as expressed in their local legislatures. They demanded their rights as Englishmen and "no taxation without representation". The British insisted on administering the empire through Parliament, and the conflict escalated into war.[95]

The Second Continental Congress unanimously adopted the Declaration of Independence, which asserted that Great Britain was not protecting Americans' unalienable rights. July 4 is celebrated annually as Independence Day.[96] In 1777, the Articles of Confederation established a decentralized government that operated until 1789.[96]

Following the decisive Franco-American victory at Yorktown in 1781,[97] Britain signed the peace treaty of 1783, and American sovereignty was internationally recognized and the country was granted all lands east of the Mississippi River. Nationalists led the Philadelphia Convention of 1787 in writing the United States Constitution, ratified in state conventions in 1788. The federal government was reorganized into three branches, on the principle of creating salutary checks and balances, in 1789. George Washington, who had led the Continental Army to victory, was the first president elected under the new constitution. The Bill of Rights, forbidding federal restriction of personal freedoms and guaranteeing a range of legal protections, was adopted in 1791.[98]

Although the federal government criminalized the international slave trade in 1808, after 1820, cultivation of the highly profitable cotton crop exploded in the Deep South, and along with it, the slave population.[99][100][101] The Second Great Awakening, especially 1800–1840, converted millions to evangelical Protestantism. In the North, it energized multiple social reform movements, including abolitionism;[102] in the South, Methodists and Baptists proselytized among slave populations.[103]

Americans' eagerness to expand westward prompted a long series of American Indian Wars.[104] The Louisiana Purchase of French-claimed territory in 1803 almost doubled the nation's area.[105] The War of 1812, declared against Britain over various grievances and fought to a draw, strengthened U.S. nationalism.[106] A series of military incursions into Florida led Spain to cede it and other Gulf Coast territory in 1819.[107] The expansion was aided by steam power, when steamboats began traveling along America's large water systems, many of which were connected by new canals, such as the Erie and the I&M; then, even faster railroads began their stretch across the nation's land.[108]

From 1820 to 1850, Jacksonian democracy began a set of reforms which included wider white male suffrage; it led to the rise of the Second Party System of Democrats and Whigs as the dominant parties from 1828 to 1854. The Trail of Tears in the 1830s exemplified the Indian removal policy that forcibly resettled Indians into the west on Indian reservations. The U.S. annexed the Republic of Texas in 1845 during a period of expansionist Manifest destiny.[109] The 1846 Oregon Treaty with Britain led to U.S. control of the present-day American Northwest.[110] Victory in the Mexican–American War resulted in the 1848 Mexican Cession of California and much of the present-day American Southwest.[111] The California Gold Rush of 1848–49 spurred migration to the Pacific coast, which led to the California Genocide[112][113][114][115] and the creation of additional western states.[116] After the Civil War, new transcontinental railways made relocation easier for settlers, expanded internal trade and increased conflicts with Native Americans.[117] In 1869, a new Peace Policy nominally promised to protect Native Americans from abuses, avoid further war, and secure their eventual U.S. citizenship. Nonetheless, large-scale conflicts continued throughout the West into the 1900s.

Civil War and Reconstruction era

Irreconcilable sectional conflict regarding the slavery of Africans and African Americans ultimately led to the American Civil War.[118] Initially, states entering the Union had alternated between slave and free states, keeping a sectional balance in the Senate, while free states outstripped slave states in population and in the House of Representatives. But with additional western territory and more free-soil states, tensions between slave and free states mounted with arguments over federalism and disposition of the territories, as well as whether to expand or restrict slavery.[119]

With the 1860 election of Republican Abraham Lincoln, conventions in thirteen slave states ultimately declared secession and formed the Confederate States of America (the "South" or the "Confederacy"), while the federal government (the "Union") maintained that secession was illegal.[119] In order to bring about this secession, military action was initiated by the secessionists, and the Union responded in kind. The ensuing war would become the deadliest military conflict in American history, resulting in the deaths of approximately 618,000 soldiers as well as many civilians.[120] The Union initially simply fought to keep the country united. Nevertheless, as casualties mounted after 1863 and Lincoln delivered his Emancipation Proclamation, the main purpose of the war from the Union's viewpoint became the abolition of slavery. Indeed, when the Union ultimately won the war in April 1865, each of the states in the defeated South was required to ratify the Thirteenth Amendment, which prohibited slavery.

The government enacted three constitutional amendments in the years after the war: the aforementioned Thirteenth as well as the Fourteenth Amendment providing citizenship to the nearly four million African Americans who had been slaves,[121] and the Fifteenth Amendment ensuring in theory that African Americans had the right to vote. The war and its resolution led to a substantial increase in federal power[122] aimed at reintegrating and rebuilding the South while guaranteeing the rights of the newly freed slaves.

Reconstruction began in earnest following the war. While President Lincoln attempted to foster friendship and forgiveness between the Union and the former Confederacy, his assassination on April 14, 1865, drove a wedge between North and South again. Republicans in the federal government made it their goal to oversee the rebuilding of the South and to ensure the rights of African Americans. They persisted until the Compromise of 1877 when the Republicans agreed to cease protecting the rights of African Americans in the South in order for Democrats to concede the presidential election of 1876.

Southern white Democrats, calling themselves "Redeemers," took control of the South after the end of Reconstruction. From 1890 to 1910 the Redeemers established so-called Jim Crow laws, disenfranchising most blacks and some poor whites throughout the region. Blacks faced racial segregation, especially in the South.[123] They also occasionally experienced vigilante violence, including lynching.[124]

Further immigration, expansion, and industrialization

In the North, urbanization and an unprecedented influx of immigrants from Southern and Eastern Europe supplied a surplus of labor for the country's industrialization and transformed its culture.[126] National infrastructure including telegraph and transcontinental railroads spurred economic growth and greater settlement and development of the American Old West. The later invention of electric light and the telephone would also affect communication and urban life.[127]

The United States fought Indian Wars west of the Mississippi River from 1810 to at least 1890.[128] Most of these conflicts ended with the cession of Native American territory and their confinement to Indian reservations. This further expanded acreage under mechanical cultivation, increasing surpluses for international markets.[129] Mainland expansion also included the purchase of Alaska from Russia in 1867.[130] In 1893, pro-American elements in Hawaii overthrew the monarchy and formed the Republic of Hawaii, which the U.S. annexed in 1898. Puerto Rico, Guam, and the Philippines were ceded by Spain in the same year, following the Spanish–American War.[131] American Samoa was acquired by the United States in 1900 after the end of the Second Samoan Civil War.[132] The U.S. Virgin Islands were purchased from Denmark in 1917.[133]

Rapid economic development during the late 19th and early 20th centuries fostered the rise of many prominent industrialists. Tycoons like Cornelius Vanderbilt, John D. Rockefeller, and Andrew Carnegie led the nation's progress in railroad, petroleum, and steel industries. Banking became a major part of the economy, with J. P. Morgan playing a notable role. The American economy boomed, becoming the world's largest, and the United States achieved great power status.[134] These dramatic changes were accompanied by social unrest and the rise of populist, socialist, and anarchist movements.[135] This period eventually ended with the advent of the Progressive Era, which saw significant reforms including women's suffrage, alcohol prohibition, regulation of consumer goods, greater antitrust measures to ensure competition and attention to worker conditions.[136][137][138]

World War I, Great Depression, and World War II

The United States remained neutral from the outbreak of World War I in 1914 until 1917, when it joined the war as an "associated power," alongside the formal Allies of World War I, helping to turn the tide against the Central Powers. In 1919, President Woodrow Wilson took a leading diplomatic role at the Paris Peace Conference and advocated strongly for the U.S. to join the League of Nations. However, the Senate refused to approve this and did not ratify the Treaty of Versailles that established the League of Nations.[139]

In 1920, the women's rights movement won passage of a constitutional amendment granting women's suffrage.[140] The 1920s and 1930s saw the rise of radio for mass communication and the invention of early television.[141] The prosperity of the Roaring Twenties ended with the Wall Street Crash of 1929 and the onset of the Great Depression. After his election as president in 1932, Franklin D. Roosevelt responded with the New Deal.[142] The Great Migration of millions of African Americans out of the American South began before World War I and extended through the 1960s;[143] whereas the Dust Bowl of the mid-1930s impoverished many farming communities and spurred a new wave of western migration.[144]

At first effectively neutral during World War II, the United States began supplying materiel to the Allies in March 1941 through the Lend-Lease program. On December 7, 1941, the Empire of Japan launched a surprise attack on Pearl Harbor, prompting the United States to join the Allies against the Axis powers.[145] Although Japan attacked the United States first, the U.S. nonetheless pursued a "Europe first" defense policy.[146] The United States thus left its vast Asian colony, the Philippines, isolated and fighting a losing struggle against Japanese invasion and occupation, as military resources were devoted to the European theater. During the war, the United States was referred to as one of the "Four Policemen"[147] of Allies power who met to plan the postwar world, along with Britain, the Soviet Union and China.[148][149] Although the nation lost around 400,000 military personnel,[150] it emerged relatively undamaged from the war with even greater economic and military influence.[151]

The United States played a leading role in the Bretton Woods and Yalta conferences with the United Kingdom, the Soviet Union, and other Allies, which signed agreements on new international financial institutions and Europe's postwar reorganization. As an Allied victory was won in Europe, a 1945 international conference held in San Francisco produced the United Nations Charter, which became active after the war.[152] The United States and Japan then fought each other in the largest naval battle in history, the Battle of Leyte Gulf.[153][154] The United States eventually developed the first nuclear weapons and used them on Japan in the cities of Hiroshima and Nagasaki; the Japanese surrendered on September 2, ending World War II.[155][156]

Cold War and civil rights era

After World War II, the United States and the Soviet Union competed for power, influence, and prestige during what became known as the Cold War, driven by an ideological divide between capitalism and communism.[157] They dominated the military affairs of Europe, with the U.S. and its NATO allies on one side and the USSR and its Warsaw Pact allies on the other. The U.S. developed a policy of containment towards the expansion of communist influence. While the U.S. and Soviet Union engaged in proxy wars and developed powerful nuclear arsenals, the two countries avoided direct military conflict.

The United States often opposed Third World movements that it viewed as Soviet-sponsored, and occasionally pursued direct action for regime change against left-wing governments, even supporting right-wing authoritarian governments at times.[158] American troops fought communist Chinese and North Korean forces in the Korean War of 1950–53.[159] The Soviet Union's 1957 launch of the first artificial satellite and its 1961 launch of the first manned spaceflight initiated a "Space Race" in which the United States became the first nation to land a man on the moon in 1969.[159] A proxy war in Southeast Asia eventually evolved into full American participation, as the Vietnam War.

At home, the U.S. experienced sustained economic expansion and a rapid growth of its population and middle class. Construction of an Interstate Highway System transformed the nation's infrastructure over the following decades. Millions moved from farms and inner cities to large suburban housing developments.[160][161] In 1959 Hawaii became the 50th and last U.S. state added to the country.[162] The growing Civil Rights Movement used nonviolence to confront segregation and discrimination, with Martin Luther King Jr. becoming a prominent leader and figurehead. A combination of court decisions and legislation, culminating in the Civil Rights Act of 1968, sought to end racial discrimination.[163][164][165] Meanwhile, a counterculture movement grew which was fueled by opposition to the Vietnam war, black nationalism, and the sexual revolution.

The launch of a "War on Poverty" expanded entitlements and welfare spending, including the creation of Medicare and Medicaid, two programs that provide health coverage to the elderly and poor, respectively, and the means-tested Food Stamp Program and Aid to Families with Dependent Children.[166]

The 1970s and early 1980s saw the onset of stagflation. After his election in 1980, President Ronald Reagan responded to economic stagnation with free-market oriented reforms. Following the collapse of détente, he abandoned "containment" and initiated the more aggressive "rollback" strategy towards the USSR.[167][168][169][170][171] After a surge in female labor participation over the previous decade, by 1985 the majority of women aged 16 and over were employed.[172]

The late 1980s brought a "thaw" in relations with the USSR, and its collapse in 1991 finally ended the Cold War.[173][174][175][176] This brought about unipolarity[177] with the U.S. unchallenged as the world's dominant superpower. The concept of Pax Americana, which had appeared in the post-World War II period, gained wide popularity as a term for the post-Cold War new world order.

Contemporary history

After the Cold War, the conflict in the Middle East triggered a crisis in 1990, when Iraq under Saddam Hussein invaded and attempted to annex Kuwait, an ally of the United States. Fearing the instability would spread to other regions, President George H. W. Bush launched Operation Desert Shield, a defensive force buildup in Saudi Arabia, and Operation Desert Storm, in a staging titled the Gulf War; waged by coalition forces from 34 nations, led by the United States against Iraq ending in the expulsion of Iraqi forces from Kuwait and restoration of the monarchy.[178]

Originating within U.S. military defense networks, the Internet spread to international academic platforms and then to the public in the 1990s, greatly affecting the global economy, society, and culture.[179] Due to the dot-com boom, stable monetary policy, and reduced social welfare spending, the 1990s saw the longest economic expansion in modern U.S. history.[180] Beginning in 1994, the U.S. entered into the North American Free Trade Agreement (NAFTA), prompting trade among the U.S., Canada, and Mexico to soar.[181]

On September 11, 2001, Al-Qaeda terrorists struck the World Trade Center in New York City and the Pentagon near Washington, D.C., killing nearly 3,000 people.[182] In response, the United States launched the War on Terror, which included a war in Afghanistan and the 2003–11 Iraq War.[183][184]

Government policy designed to promote affordable housing,[185] widespread failures in corporate and regulatory governance,[186] and historically low interest rates set by the Federal Reserve[187] led to the mid-2000s housing bubble, which culminated with the 2008 financial crisis, the nation's largest economic contraction since the Great Depression.[188] Barack Obama, the first African-American[189] and multiracial[190] president, was elected in 2008 amid the crisis,[191] and subsequently passed stimulus measures and the Dodd–Frank Act in an attempt to mitigate its negative effects and ensure there would not be a repeat of the crisis. In 2010, the Obama administration passed the Affordable Care Act, which made the most sweeping reforms to the nation's healthcare system in nearly five decades, including mandates, subsidies and insurance exchanges.

American forces in Iraq were withdrawn in large numbers in 2009 and 2010, and the war in the region was declared formally over in December 2011.[192] But months earlier, Operation Neptune Spear led to the death of the leader of Al-Qaeda in Pakistan.[193] In the presidential election of 2016, Republican Donald Trump was elected as the 45th president of the United States, making him both the oldest and wealthiest person elected president in the country's history.[194]

On January 20, 2020, the first case of COVID-19 in the United States was confirmed.[195] Over the course of the next five months, the disease has affected over 3 million Americans and killed over 130,000 people.[196] The United States is, by far, the country with the most cases of COVID-19 as of June 10, 2020.[197]

Geography, climate, and environment

The 48 contiguous states and the District of Columbia occupy a combined area of 3,119,884.69 square miles (8,080,464.3 km2). Of this area, 2,959,064.44 square miles (7,663,941.7 km2) is contiguous land, composing 83.65% of total U.S. land area.[198][199] Hawaii, occupying an archipelago in the central Pacific, southwest of North America, is 10,931 square miles (28,311 km2) in area. The populated territories of Puerto Rico, American Samoa, Guam, Northern Mariana Islands, and U.S. Virgin Islands together cover 9,185 square miles (23,789 km2).[200] Measured by only land area, the United States is third in size behind Russia and China, just ahead of Canada.[201]

The United States is the world's third- or fourth-largest nation by total area (land and water), ranking behind Russia and Canada and nearly equal to China. The ranking varies depending on how two territories disputed by China and India are counted, and how the total size of the United States is measured.[e][202][203]

The coastal plain of the Atlantic seaboard gives way further inland to deciduous forests and the rolling hills of the Piedmont.[204] The Appalachian Mountains divide the eastern seaboard from the Great Lakes and the grasslands of the Midwest.[205] The MississippiMissouri River, the world's fourth longest river system, runs mainly north–south through the heart of the country. The flat, fertile prairie of the Great Plains stretches to the west, interrupted by a highland region in the southeast.[205]

The Rocky Mountains, west of the Great Plains, extend north to south across the country, peaking around 14,000 feet (4,300 m) in Colorado.[206] Farther west are the rocky Great Basin and deserts such as the Chihuahua and Mojave.[207] The Sierra Nevada and Cascade mountain ranges run close to the Pacific coast, both ranges reaching altitudes higher than 14,000 feet (4,300 m). The lowest and highest points in the contiguous United States are in the state of California,[208] and only about 84 miles (135 km) apart.[209] At an elevation of 20,310 feet (6,190.5 m), Alaska's Denali is the highest peak in the country and in North America.[210] Active volcanoes are common throughout Alaska's Alexander and Aleutian Islands, and Hawaii consists of volcanic islands. The supervolcano underlying Yellowstone National Park in the Rockies is the continent's largest volcanic feature.[211]

The United States, with its large size and geographic variety, includes most climate types. To the east of the 100th meridian, the climate ranges from humid continental in the north to humid subtropical in the south.[212] The Great Plains west of the 100th meridian are semi-arid. Much of the Western mountains have an alpine climate. The climate is arid in the Great Basin, desert in the Southwest, Mediterranean in coastal California, and oceanic in coastal Oregon and Washington and southern Alaska. Most of Alaska is subarctic or polar. Hawaii and the southern tip of Florida are tropical, as well as its territories in the Caribbean and the Pacific.[213] States bordering the Gulf of Mexico are prone to hurricanes, and most of the world's tornadoes occur in the country, mainly in Tornado Alley areas in the Midwest and South.[214] Overall, the United States has the world's most violent weather, receiving more high-impact extreme weather incidents than any other country in the world.[215]

Wildlife and conservation

The U.S. ecology is megadiverse: about 17,000 species of vascular plants occur in the contiguous United States and Alaska, and more than 1,800 species of flowering plants are found in Hawaii, few of which occur on the mainland.[217] The United States is home to 428 mammal species, 784 bird species, 311 reptile species, and 295 amphibian species,[218] as well as about 91,000 insect species.[219]

There are 62 national parks and hundreds of other federally managed parks, forests, and wilderness areas.[220] Altogether, the government owns about 28% of the country's land area,[221] mostly in the western states.[222] Most of this land is protected, though some is leased for oil and gas drilling, mining, logging, or cattle ranching, and about .86% is used for military purposes.[223][224]

Environmental issues include debates on oil and nuclear energy, dealing with air and water pollution, the economic costs of protecting wildlife, logging and deforestation,[225][226] and international responses to global warming.[227][228] The most prominent environmental agency is the Environmental Protection Agency (EPA), created by presidential order in 1970.[229] The idea of wilderness has shaped the management of public lands since 1964, with the Wilderness Act.[230] The Endangered Species Act of 1973 is intended to protect threatened and endangered species and their habitats, which are monitored by the United States Fish and Wildlife Service.[231]

Note that the census numbers do
not include Native Americans until 1860.[234]

The U.S. Census Bureau officially estimated the country's population to be 328,239,523 as of July 1, 2019.[232] In addition, the Census Bureau provides a continuously updated U.S. Population Clock that approximates the latest population of the 50 states and District of Columbia based on the Bureau's most recent demographic trends.[235] According to the clock, on May 23, 2020, the U.S. population exceeded 329 million residents, with a net gain of one person every 19 seconds, or about 4,547 people per day. The United States is the third most populous nation in the world, after China and India. In 2018 the median age of the United States population was 38.1 years.[236]

In 2018, there were almost 90 million immigrants and U.S.-born children of immigrants (second-generation Americans) in the United States, accounting for 28% of the overall U.S. population.[237] The United States has a very diverse population; 37 ancestry groups have more than one million members.[238] German Americans are the largest ethnic group (more than 50 million)—followed by Irish Americans (circa 37 million), Mexican Americans (circa 31 million) and English Americans (circa 28 million).[239][240]

White Americans (mostly European ancestry) are the largest racial group at 73.1% of the population; African Americans are the nation's largest racial minority and third-largest ancestry group.[238] Asian Americans are the country's second-largest racial minority; the three largest Asian American ethnic groups are Chinese Americans, Filipino Americans, and Indian Americans.[238] The largest American community with European ancestry is German Americans, which consists of more than 14% of the total population.[241] In 2010, the U.S. population included an estimated 5.2 million people with some American Indian or Alaska Native ancestry (2.9 million exclusively of such ancestry) and 1.2 million with some native Hawaiian or Pacific island ancestry (0.5 million exclusively).[242] The census counted more than 19 million people of "Some Other Race" who were "unable to identify with any" of its five official race categories in 2010, more than 18.5 million (97%) of whom are of Hispanic ethnicity.[242]

Minorities, defined by the Census Bureau as all individuals aside from non-Hispanic, non-multiracial whites, constituted 37% of the population in 2012.[243] More than 50% of infants less than a year old are members of minority groups.[244][245] These groups are projected to collectively make up a majority of the population by 2044.[244]

In 2017, out of the U.S. foreign-born population, some 45% (20.7 million) were naturalized citizens, 27% (12.3 million) were lawful permanent residents (including many eligible to become citizens), 6% (2.2 million) were temporary lawful residents, and 23% (10.5 million) were unauthorized immigrants.[246] Among current living immigrants to the U.S., the top five countries of birth are Mexico, China, India, the Philippines and El Salvador. Until 2017 and 2018, the United States led the word in refugee resettlement for decades, admitted more refugees than the rest of the world combined.[247] From fiscal year 1980 until 2017, 55% of refugees came from Asia, 27% from Europe, 13% from Africa, and 4% from Latin America.[247]

A 2017 Gallup poll concluded that 4.5% of adult Americans identified as LGBT with 5.1% of women identifying as LGBT, compared with 3.9% of men.[248] The highest percentage came from the District of Columbia (10%), while the lowest state was North Dakota at 1.7%.[249]

A 2017 United Nations report projected that the U.S. would be one of nine countries in which world population growth through 2050 would be concentrated.[250] A 2020 U.S. Census Bureau report projected the population of the country could be anywhere between 320 million and 447 million by 2060, depending on the rate of in-migration; in all projected scenarios, a lower fertility rate and increases in life expectancy would result in an aging population.[251]

The population growth of Hispanic and Latino Americans is a major demographic trend. The 50.5 million Americans of Hispanic descent[242] are identified as sharing a distinct "ethnicity" by the Census Bureau; 64% of Hispanic Americans are of Mexican descent.[252] Between 2000 and 2010, the country's Hispanic population increased 43% while the non-Hispanic population rose just 4.9%.[253]

The United States has an annual birth rate of 13 per 1,000, which is five births per 1,000 below the world average.[254] Its population growth rate is positive at 0.7%, higher than that of many developed nations.[255] In fiscal year 2017, more than a million immigrants (most of whom entered through family reunification) were granted legal residence.[256] In absolute numbers, the number of foreign-born U.S. residents is at a record high (44.4 million in 2017); however as a proportion of the overall population, the current foreign-born share (13.6% of the total population) is lower than the share at the peak in 1890 (14.8% of the total population).[246]

About 82% of Americans live in urban areas (including suburbs);[203] about half of those reside in cities with populations over 50,000.[257] In 2008, 273 incorporated municipalities had populations over 100,000, nine cities had more than one million residents, and four cities had over two million (namely New York, Los Angeles, Chicago, and Houston).[258] Estimates for the year 2018 show that 53 metropolitan areas have populations greater than one million. Many metros in the South, Southwest and West grew significantly between 2010 and 2018. The Dallas and Houston metros increased by more than a million people, while the Washington, D.C., Miami, Atlanta, and Phoenix metros all grew by more than 500,000 people.


English (specifically, American English) is the de facto national language of the United States. Although there is no official language at the federal level, some laws—such as U.S. naturalization requirements—standardize English. In 2010, about 230 million, or 80% of the population aged five years and older, spoke only English at home. 12% of the population speaks Spanish at home, making it the second most common language. Spanish is also the most widely taught second language.[259][260]

Both Hawaiian and English are official languages in Hawaii.[261] In addition to English, Alaska recognizes twenty official Native languages,[262][k] and South Dakota recognizes Sioux.[263] While neither has an official language, New Mexico has laws providing for the use of both English and Spanish, as Louisiana does for English and French.[264] Other states, such as California, mandate the publication of Spanish versions of certain government documents including court forms.[265]

Several insular territories grant official recognition to their native languages, along with English: Samoan[266] is officially recognized by American Samoa and Chamorro[267] is an official language of Guam. Both Carolinian and Chamorro have official recognition in the Northern Mariana Islands.[268] Spanish is an official language of Puerto Rico and is more widely spoken than English there.[269]

The most widely taught foreign languages in the United States, in terms of enrollment numbers from kindergarten through university undergraduate education, are Spanish (around 7.2 million students), French (1.5 million), and German (500,000). Other commonly taught languages include Latin, Japanese, ASL, Italian, and Chinese.[270][271] 18% of all Americans claim to speak both English and another language.[272]

The First Amendment of the U.S. Constitution guarantees the free exercise of religion and forbids Congress from passing laws respecting its establishment.

In a 2013 survey, 56% of Americans said religion played a "very important role in their lives," a far higher figure than that of any other Western nation.[276] In a 2009 Gallup poll, 42% of Americans said they attended church weekly or almost weekly; the figures ranged from a low of 23% in Vermont to a high of 63% in Mississippi.[277]

In a 2014 survey, 70.6% of adults in the United States identified themselves as Christians;[278] Protestants accounted for 46.5%, while Roman Catholics, at 20.8%, formed the largest single Christian group.[279] In 2014, 5.9% of the U.S. adult population claimed a non-Christian religion.[280] These include Judaism (1.9%), Islam (0.9%), Hinduism (0.7%), and Buddhism (0.7%).[280] The survey also reported that 22.8% of Americans described themselves as agnostic, atheist or simply having no religion—up from 8.2% in 1990.[279][281][282] There are also Unitarian Universalist, Scientologist, Baha'i, Sikh, Jain, Shinto, Zoroastrian, Confucian, Satanist, Taoist, Druid, Native American, Afro-American, traditional African, Wiccan, Gnostic, humanist and deist communities.[283][284]

Protestantism is the largest Christian religious grouping in the United States, accounting for almost half of all Americans. Baptists collectively form the largest branch of Protestantism at 15.4%,[285] and the Southern Baptist Convention is the largest individual Protestant denomination at 5.3% of the U.S. population.[285] Apart from Baptists, other Protestant categories include nondenominational Protestants, Methodists, Pentecostals, unspecified Protestants, Lutherans, Presbyterians, Congregationalists, other Reformed, Episcopalians/Anglicans, Quakers, Adventists, Holiness, Christian fundamentalists, Anabaptists, Pietists, and multiple others.[285]

As with other Western countries, the U.S. is becoming less religious. Irreligion is growing rapidly among Americans under 30.[286] Polls show that overall American confidence in organized religion has been declining since the mid to late 1980s,[287] and that younger Americans, in particular, are becoming increasingly irreligious.[280][288] In a 2012 study, the Protestant share of the U.S. population had dropped to 48%, thus ending its status as religious category of the majority for the first time.[289][290] Americans with no religion have 1.7 children compared to 2.2 among Christians. The unaffiliated are less likely to marry with 37% marrying compared to 52% of Christians.[291]

The Bible Belt is an informal term for a region in the Southern United States in which socially conservative evangelical Protestantism is a significant part of the culture and Christian church attendance across the denominations is generally higher than the nation's average. By contrast, religion plays the least important role in New England and in the Western United States.[277]

Family structure

As of 2018, 52% of Americans age 15 and over were married, 6% were widowed, 10% were divorced, and 32% had never been married.[292] Women now work mostly outside the home and receive the majority of bachelor's degrees.[293]

The U.S. teenage pregnancy rate is 26.5 per 1,000 women. The rate has declined by 57% since 1991.[294] Abortion is legal throughout the country. Abortion rates, currently 241 per 1,000 live births and 15 per 1,000 women aged 15–44, are falling but remain higher than most Western nations.[295] In 2013, the average age at first birth was 26 and 41% of births were to unmarried women.[296]

The total fertility rate in 2016 was 1820.5 births per 1000 women.[297] Adoption in the United States is common and relatively easy from a legal point of view (compared to other Western countries).[298] As of 2001, with more than 127,000 adoptions, the U.S. accounted for nearly half of the total number of adoptions worldwide.[needs update][299] Same-sex marriage is legal nationwide, and it is legal for same-sex couples to adopt. Polygamy is illegal throughout the U.S.[300]

The U.S. has the world's highest rate of children living in single-parent households.[301]


The United States had a life expectancy of 78.6 years at birth in 2017, which was the third year of declines in life expectancy following decades of continuous increase. The recent decline, primarily among the age group 25 to 64, is largely due to sharp increases in the drug overdose and suicide rates; the country has one of the highest suicide rates among wealthy countries.[302][303] Life expectancy was highest among Asians and Hispanics and lowest among blacks.[304][305] According to CDC and Census Bureau data, deaths from suicide, alcohol and drug overdoses hit record highs in 2017.[306]

Increasing obesity in the United States and health improvements elsewhere contributed to lowering the country's rank in life expectancy from 11th in the world in 1987, to 42nd in 2007, and as of 2017 the country had the lowest life expectancy among Japan, Canada, Australia, the UK, and seven countries of western Europe.[307][308] Obesity rates have more than doubled in the last 30 years and are the highest in the industrialized world.[309][310] Approximately one-third of the adult population is obese and an additional third is overweight.[311] Obesity-related type 2 diabetes is considered epidemic by health care professionals.[312]

In 2010, coronary artery disease, lung cancer, stroke, chronic obstructive pulmonary diseases, and traffic accidents caused the most years of life lost in the U.S. Low back pain, depression, musculoskeletal disorders, neck pain, and anxiety caused the most years lost to disability. The most harmful risk factors were poor diet, tobacco smoking, obesity, high blood pressure, high blood sugar, physical inactivity, and alcohol use. Alzheimer's disease, drug abuse, kidney disease, cancer, and falls caused the most additional years of life lost over their age-adjusted 1990 per-capita rates.[313] U.S. teenage pregnancy and abortion rates are substantially higher than in other Western nations, especially among blacks and Hispanics.[314]

Health-care coverage in the United States is a combination of public and private efforts and is not universal. In 2017, 12.2% of the population did not carry health insurance.[315] The subject of uninsured and underinsured Americans is a major political issue.[316][317] Federal legislation, passed in early 2010, roughly halved the uninsured share of the population, though the bill and its ultimate effect are issues of controversy.[318][319] The U.S. health-care system far outspends any other nation, measured both in per capita spending and as percentage of GDP.[320] At the same time, the U.S. is a global leader in medical innovation.[321]


American public education is operated by state and local governments, regulated by the United States Department of Education through restrictions on federal grants. In most states, children are required to attend school from the age of six or seven (generally, kindergarten or first grade) until they turn 18 (generally bringing them through twelfth grade, the end of high school); some states allow students to leave school at 16 or 17.[322]

About 12% of children are enrolled in parochial or nonsectarian private schools. Just over 2% of children are homeschooled.[323] The U.S. spends more on education per student than any nation in the world, spending more than $11,000 per elementary student in 2010 and more than $12,000 per high school student.[324][needs update] Some 80% of U.S. college students attend public universities.[325]

Of Americans 25 and older, 84.6% graduated from high school, 52.6% attended some college, 27.2% earned a bachelor's degree, and 9.6% earned graduate degrees.[326] The basic literacy rate is approximately 99%.[203][327] The United Nations assigns the United States an Education Index of 0.97, tying it for 12th in the world.[328]

The United States has many private and public institutions of higher education. The majority of the world's top universities, as listed by various ranking organizations, are in the U.S.[329][330][331] There are also local community colleges with generally more open admission policies, shorter academic programs, and lower tuition.

In 2018, U21, a network of research-intensive universities, ranked the United States first in the world for breadth and quality of higher education, and 15th when GDP was a factor.[332] As for public expenditures on higher education, the U.S. trails some other OECD nations but spends more per student than the OECD average, and more than all nations in combined public and private spending.[324][333] As of 2018, student loan debt exceeded 1.5 trillion dollars.[334][335]

Government and politics

The United States is a federal republic of 50 states, a federal district, five territories and several uninhabited island possessions.[336][337][338] It is the world's oldest surviving federation. It is a federal republic and a representative democracy, "in which majority rule is tempered by minority rights protected by law."[339] For 2018, the U.S. ranked 25th on the Democracy Index.[340] On Transparency International's 2019 Corruption Perceptions Index its public sector position deteriorated from a score of 76 in 2015 to 69 in 2019.[341]

In the American federalist system, citizens are usually subject to three levels of government: federal, state, and local. The local government's duties are commonly split between county and municipal governments. In almost all cases, executive and legislative officials are elected by a plurality vote of citizens by district.

The government is regulated by a system of checks and balances defined by the U.S. Constitution, which serves as the country's supreme legal document.[342] The original text of the Constitution establishes the structure and responsibilities of the federal government and its relationship with the individual states. Article One protects the right to the "great writ" of habeas corpus. The Constitution has been amended 27 times;[343] the first ten amendments, which make up the Bill of Rights, and the Fourteenth Amendment form the central basis of Americans' individual rights. All laws and governmental procedures are subject to judicial review and any law ruled by the courts to be in violation of the Constitution is voided. The principle of judicial review, not explicitly mentioned in the Constitution, was established by the Supreme Court in Marbury v. Madison (1803)[344] in a decision handed down by Chief Justice John Marshall.[345]

The federal government comprises three branches:

The House of Representatives has 435 voting members, each representing a congressional district for a two-year term. House seats are apportioned among the states by population. Each state then draws single-member districts to conform with the census apportionment. The District of Columbia and the five major U.S. territories each have one member of Congress—these members are not allowed to vote.[350]

The Senate has 100 members with each state having two senators, elected at-large to six-year terms; one-third of Senate seats are up for election every two years. The District of Columbia and the five major U.S. territories do not have senators.[350] The president serves a four-year term and may be elected to the office no more than twice. The president is not elected by direct vote, but by an indirect electoral college system in which the determining votes are apportioned to the states and the District of Columbia.[351] The Supreme Court, led by the chief justice of the United States, has nine members, who serve for life.[352]

The state governments are structured in a roughly similar fashion, though Nebraska has a unicameral legislature.[353] The governor (chief executive) of each state is directly elected. Some state judges and cabinet officers are appointed by the governors of the respective states, while others are elected by popular vote.

Political divisions

The 50 states are the principal administrative divisions in the country. These are subdivided into counties or county equivalents and further divided into municipalities. The District of Columbia is a federal district that contains the capital of the United States, Washington, D.C.[354] The states and the District of Columbia choose the president of the United States. Each state has presidential electors equal to the number of their representatives and senators in Congress; the District of Columbia has three (because of the 23rd Amendment).[355] Territories of the United States such as Puerto Rico do not have presidential electors, and so people in those territories cannot vote for the president.[350]

The United States also observes tribal sovereignty of the American Indian nations to a limited degree, as it does with the states' sovereignty. American Indians are U.S. citizens and tribal lands are subject to the jurisdiction of the U.S. Congress and the federal courts. Like the states they have a great deal of autonomy, but also like the states, tribes are not allowed to make war, engage in their own foreign relations, or print and issue currency.[356]

Citizenship is granted at birth in all states, the District of Columbia, and all major U.S. territories except American Samoa.[357][358][m]

Parties and elections

The United States has operated under a two-party system for most of its history.[361] For elective offices at most levels, state-administered primary elections choose the major party nominees for subsequent general elections. Since the general election of 1856, the major parties have been the Democratic Party, founded in 1824, and the Republican Party, founded in 1854. Since the Civil War, only one third-party presidential candidate—former president Theodore Roosevelt, running as a Progressive in 1912—has won as much as 20% of the popular vote. The president and vice president are elected by the Electoral College.[362]

In American political culture, the center-right Republican Party is considered "conservative" and the center-left Democratic Party is considered "liberal."[363][364] The states of the Northeast and West Coast and some of the Great Lakes states, known as "blue states," are relatively liberal. The "red states" of the South and parts of the Great Plains and Rocky Mountains are relatively conservative.

Republican Donald Trump, the winner of the 2016 presidential election, is serving as the 45th president of the United States.[365] Leadership in the Senate includes Republican vice president Mike Pence, Republican president pro tempore Chuck Grassley, Majority Leader Mitch McConnell, and Minority Leader Chuck Schumer.[366] Leadership in the House includes Speaker of the House Nancy Pelosi, Majority Leader Steny Hoyer, and Minority Leader Kevin McCarthy.[367]

In the 116th United States Congress, the House of Representatives is controlled by the Democratic Party and the Senate is controlled by the Republican Party, giving the U.S. a split Congress. The Senate consists of 53 Republicans and 45 Democrats with two Independents who caucus with the Democrats; the House consists of 233 Democrats, 196 Republicans, and 1 Libertarian.[368] Of state governors, there are 26 Republicans and 24 Democrats. Among the D.C. mayor and the five territorial governors, there are two Republicans, one Democrat, one New Progressive, and two Independents.[369]

Foreign relations

The United States has an established structure of foreign relations. It is a permanent member of the United Nations Security Council. New York City is home to the United Nations Headquarters. Almost all countries have embassies in Washington, D.C., and many have consulates around the country. Likewise, nearly all nations host American diplomatic missions. However, Iran, North Korea, Bhutan, and the Republic of China (Taiwan) do not have formal diplomatic relations with the United States (although the U.S. still maintains unofficial relations with Bhutan and Taiwan).[370] It is a member of the G7,[371] G20, and OECD.

The United States has a "Special Relationship" with the United Kingdom[372] and strong ties with India, Canada,[373] Australia,[374] New Zealand,[375] the Philippines,[376] Japan,[377] South Korea,[378] Israel,[379] and several European Union countries, including France, Italy, Germany, Spain and Poland.[380] It works closely with fellow NATO members on military and security issues and with its neighbors through the Organization of American States and free trade agreements such as the trilateral North American Free Trade Agreement with Canada and Mexico. Colombia is traditionally considered by the United States as its most loyal ally in South America.[381][382]

The U.S. exercises full international defense authority and responsibility for Micronesia, the Marshall Islands and Palau through the Compact of Free Association.[383]

Government finance

Taxation in the United States is levied at the federal, state, and local government levels. This includes taxes on income, payroll, property, sales, imports, estates, and gifts, as well as various fees. Taxation in the United States is based on citizenship, not residency.[384] Both non-resident citizens and Green Card holders living abroad are taxed on their income irrespective of where they live or where their income is earned. The United States is one of the only countries in the world to do so.[385]

In 2010 taxes collected by federal, state and municipal governments amounted to 24.8% of GDP.[386] Based on CBO estimates,[387] under 2013 tax law the top 1% will be paying the highest average tax rates since 1979, while other income groups will remain at historic lows.[388] For 2018, the effective tax rate for the wealthiest 400 households was 23%, compared to 24.2% for the bottom half of U.S. households.[389]

During fiscal year 2012, the federal government spent $3.54 trillion on a budget or cash basis, down $60 billion or 1.7% vs. fiscal year 2011 spending of $3.60 trillion. Major categories of fiscal year 2012 spending included: Medicare & Medicaid (23%), Social Security (22%), Defense Department (19%), non-defense discretionary (17%), other mandatory (13%) and interest (6%).[391]

The total national debt of the United States in the United States was $18.527 trillion (106% of the GDP) in 2014.[392][n] The United States has the largest external debt in the world[396] and the 34th largest government debt as a % of GDP in the world.[397]


The president is the commander-in-chief of the country's armed forces and appoints its leaders, the Secretary of Defense and the Joint Chiefs of Staff. The United States Department of Defense administers the armed forces, including the Army, Marine Corps, Navy, Air Force, and Space Force. The Coast Guard is run by the Department of Homeland Security in peacetime and by the Department of the Navy during times of war. In 2008, the armed forces had 1.4 million personnel on active duty. The Reserves and National Guard brought the total number of troops to 2.3 million. The Department of Defense also employed about 700,000 civilians, not including contractors.[398]

Military service is voluntary, though conscription may occur in wartime through the Selective Service System.[399] American forces can be rapidly deployed by the Air Force's large fleet of transport aircraft, the Navy's 11 active aircraft carriers, and Marine expeditionary units at sea with the Navy's Atlantic and Pacific fleets. The military operates 865 bases and facilities abroad,[400] and maintains deployments greater than 100 active duty personnel in 25 foreign countries.[401]

The military budget of the United States in 2011 was more than $700 billion, 41% of global military spending. At 4.7% of GDP, the rate was the second-highest among the top 15 military spenders, after Saudi Arabia.[402] Defense spending plays a major role in science and technology investment, with roughly half of U.S. federal research and development funded by the Department of Defense.[403] Defense's share of the overall U.S. economy has generally declined in recent decades, from Cold War peaks of 14.2% of GDP in 1953 and 69.5% of federal outlays in 1954 to 4.7% of GDP and 18.8% of federal outlays in 2011.[404]

The country is one of the five recognized nuclear weapons states and possesses the second largest stockpile of nuclear weapons in the world.[405] More than 90% of the world's 14,000 nuclear weapons are owned by Russia and the United States.[406]

Law enforcement and crime

Law enforcement in the United States is primarily the responsibility of local police departments and sheriff's offices, with state police providing broader services. Federal agencies such as the Federal Bureau of Investigation (FBI) and the U.S. Marshals Service have specialized duties, including protecting civil rights, national security and enforcing U.S. federal courts' rulings and federal laws.[407] State courts conduct most criminal trials while federal courts handle certain designated crimes as well as certain appeals from the state criminal courts.

A cross-sectional analysis of the World Health Organization Mortality Database from 2010 showed that United States "homicide rates were 7.0 times higher than in other high-income countries, driven by a gun homicide rate that was 25.2 times higher."[408] In 2016, the US murder rate was 5.4 per 100,000.[409] Gun ownership rights, guaranteed by the Second Amendment, continue to be the subject of contention.

The United States has the highest documented incarceration rate and largest prison population in the world.[410] As of 2020, the Prison Policy Initiative reported that there were some 2.3 million people incarcerated.[411] The imprisonment rate for all prisoners sentenced to more than a year in state or federal facilities is 478 per 100,000 in 2013.[412] According to the Federal Bureau of Prisons, the majority of inmates held in federal prisons are convicted of drug offenses.[413] About 9% of prisoners are held in privatized prisons.[411] The practice of privately operated prisons began in the 1980s and has been a subject of contention.[414]

Capital punishment is sanctioned in the United States for certain federal and military crimes, and at the state level in 30 states.[415][416] No executions took place from 1967 to 1977, owing in part to a U.S. Supreme Court ruling striking down arbitrary imposition of the death penalty. Since the decision there have been more than 1,300 executions, a majority of these taking place in three states: Texas, Virginia, and Oklahoma.[417] Meanwhile, several states have either abolished or struck down death penalty laws. In 2019, the country had the sixth-highest number of executions in the world, following China, Iran, Saudi Arabia, Iraq, and Egypt.[418]

According to the International Monetary Fund, the U.S. GDP of $16.8 trillion constitutes 24% of the gross world product at market exchange rates and over 19% of the gross world product at purchasing power parity (PPP).[426] The United States is the largest importer of goods and second-largest exporter, though exports per capita are relatively low. In 2010, the total U.S. trade deficit was $635 billion.[427] Canada, China, Mexico, Japan, and Germany are its top trading partners.[428]

From 1983 to 2008, U.S. real compounded annual GDP growth was 3.3%, compared to a 2.3% weighted average for the rest of the G7.[429] The country ranks ninth in the world in nominal GDP per capita[430] and sixth in GDP per capita at PPP.[426] The U.S. dollar is the world's primary reserve currency.[431]

In 2009, the private sector was estimated to constitute 86.4% of the economy.[434] While its economy has reached a postindustrial level of development, the United States remains an industrial power.[435] Consumer spending comprised 68% of the U.S. economy in 2015.[436] In August 2010, the American labor force consisted of 154.1 million people (50%). With 21.2 million people, government is the leading field of employment. The largest private employment sector is health care and social assistance, with 16.4 million people. It has a smaller welfare state and redistributes less income through government action than most European nations.[437]

The United States is the only advanced economy that does not guarantee its workers paid vacation[438] and is one of a few countries in the world without paid family leave as a legal right.[439] While federal law does not require sick leave, it is a common benefit for government workers and full-time employees at corporations.[440] 74% of full-time American workers get paid sick leave, according to the Bureau of Labor Statistics, although only 24% of part-time workers get the same benefits.[440] In 2009, the United States had the third-highest workforce productivity per person in the world, behind Luxembourg and Norway. It was fourth in productivity per hour, behind those two countries and the Netherlands.[441]

Science and technology

The United States has been a leader in technological innovation since the late 19th century and scientific research since the mid-20th century. Methods for producing interchangeable parts were developed by the U.S. War Department by the Federal Armories during the first half of the 19th century. This technology, along with the establishment of a machine tool industry, enabled the U.S. to have large-scale manufacturing of sewing machines, bicycles, and other items in the late 19th century and became known as the American system of manufacturing. Factory electrification in the early 20th century and introduction of the assembly line and other labor-saving techniques created the system of mass production.[442] In the 21st century, approximately two-thirds of research and development funding comes from the private sector.[443] The United States leads the world in scientific research papers and impact factor.[444][445]

In 1876, Alexander Graham Bell was awarded the first U.S. patent for the telephone. Thomas Edison's research laboratory, one of the first of its kind, developed the phonograph, the first long-lasting light bulb, and the first viable movie camera.[446] The latter led to emergence of the worldwide entertainment industry. In the early 20th century, the automobile companies of Ransom E. Olds and Henry Ford popularized the assembly line. The Wright brothers, in 1903, made the first sustained and controlled heavier-than-air powered flight.[447]

The rise of fascism and Nazism in the 1920s and 30s led many European scientists, including Albert Einstein, Enrico Fermi, and John von Neumann, to immigrate to the United States.[448] During World War II, the Manhattan Project developed nuclear weapons, ushering in the Atomic Age, while the Space Race produced rapid advances in rocketry, materials science, and aeronautics.[449][450]

The invention of the transistor in the 1950s, a key active component in practically all modern electronics, led to many technological developments and a significant expansion of the U.S. technology industry.[451] This, in turn, led to the establishment of many new technology companies and regions around the country such as Silicon Valley in California. Advancements by American microprocessor companies such as Advanced Micro Devices (AMD), and Intel along with both computer software and hardware companies that include Adobe Systems, Apple Inc., IBM, Microsoft, and Sun Microsystems created and popularized the personal computer. The ARPANET was developed in the 1960s to meet Defense Department requirements, and became the first of a series of networks which evolved into the Internet.[452]

Income, poverty and wealth

Accounting for 4.24% of the global population, Americans collectively possess 29.4% of the world's total wealth, and Americans make up roughly half of the world's population of millionaires.[453] The Global Food Security Index ranked the U.S. number one for food affordability and overall food security in March 2013.[454] Americans on average have more than twice as much living space per dwelling and per person as European Union residents, and more than every EU nation.[455] For 2017 the United Nations Development Programme ranked the United States 13th among 189 countries in its Human Development Index and 25th among 151 countries in its inequality-adjusted HDI (IHDI).[456]

Wealth, like income and taxes, is highly concentrated; the richest 10% of the adult population possess 72% of the country's household wealth, while the bottom half claim only 2%.[457] According to a September 2017 report by the Federal Reserve, the top 1% controlled 38.6% of the country's wealth in 2016.[458] According to a 2018 study by the OECD, the United States has a larger percentage of low-income workers than almost any other developed nation. This is largely because at-risk workers get almost no government support and are further set back by a very weak collective bargaining system.[459] The top one percent of income-earners accounted for 52 percent of the income gains from 2009 to 2015, where income is defined as market income excluding government transfers.[460] In 2018, U.S. income inequality reached the highest level ever recorded by the Census Bureau.[461]

After years of stagnation, median household income reached a record high in 2016 following two consecutive years of record growth. Income inequality remains at record highs however, with the top fifth of earners taking home more than half of all overall income.[463] The rise in the share of total annual income received by the top one percent, which has more than doubled from nine percent in 1976 to 20 percent in 2011, has significantly affected income inequality,[464] leaving the United States with one of the widest income distributions among OECD nations.[465] The extent and relevance of income inequality is a matter of debate.[466][467][468]

Between June 2007 and November 2008, the global recession led to falling asset prices around the world. Assets owned by Americans lost about a quarter of their value.[469] Since peaking in the second quarter of 2007, household wealth was down $14 trillion, but has since increased $14 trillion over 2006 levels.[470] At the end of 2014, household debt amounted to $11.8 trillion,[471] down from $13.8 trillion at the end of 2008.[472]

There were about 578,424 sheltered and unsheltered homeless persons in the US in January 2014, with almost two-thirds staying in an emergency shelter or transitional housing program.[473] In 2011, 16.7 million children lived in food-insecure households, about 35% more than 2007 levels, though only 1.1% of U.S. children, or 845,000, saw reduced food intake or disrupted eating patterns at some point during the year, and most cases were not chronic.[474] As of June 2018, 40 million people, roughly 12.7% of the U.S. population, were living in poverty, with 18.5 million of those living in deep poverty (a family income below one-half of the poverty threshold) and over five million live "in 'Third World' conditions." In 2016, 13.3 million children were living in poverty, which made up 32.6% of the impoverished population.[475] In 2017, the U.S. state or territory with the lowest poverty rate was New Hampshire (7.6%), and the one with the highest was American Samoa (65%).[476][477][478]



Personal transportation is dominated by automobiles, which operate on a network of 4 million miles (6.4 million kilometers) of public roads.[480] The United States has the world's second-largest automobile market,[481] and has the highest rate of per-capita vehicle ownership in the world, with 765 vehicles per 1,000 Americans (1996).[482][needs update] In 2017, there were 255,009,283 non-two wheel motor vehicles, or about 910 vehicles per 1,000 people.[483]

The civil airline industry is entirely privately owned and has been largely deregulated since 1978, while most major airports are publicly owned.[484] The three largest airlines in the world by passengers carried are US-based; American Airlines is number one after its 2013 acquisition by US Airways.[485] Of the world's 50 busiest passenger airports, 16 are in the United States, including the busiest, Hartsfield–Jackson Atlanta International Airport.[486]


The United States energy market is about 29,000 terawatt hours per year.[487] In 2005, 40% of this energy came from petroleum, 23% from coal, and 22% from natural gas. The remainder was supplied by nuclear and renewable energy sources.[488]

Since 2007, the total greenhouse gas emissions by the United States are the second highest by country, exceeded only by China.[489] The United States has historically been the world's largest producer of greenhouse gases, and greenhouse gas emissions per capita remain high.[490]


The United States is home to many cultures and a wide variety of ethnic groups, traditions, and values.[492][493] Aside from the Native American, Native Hawaiian, and Native Alaskan populations, nearly all Americans or their ancestors settled or immigrated within the past five centuries.[494] Mainstream American culture is a Western culture largely derived from the traditions of European immigrants with influences from many other sources, such as traditions brought by slaves from Africa.[492][495] More recent immigration from Asia and especially Latin America has added to a cultural mix that has been described as both a homogenizing melting pot, and a heterogeneous salad bowl in which immigrants and their descendants retain distinctive cultural characteristics.[492]

Americans have traditionally been characterized by a strong work ethic, competitiveness, and individualism,[496] as well as a unifying belief in an "American creed" emphasizing liberty, equality, private property, democracy, rule of law, and a preference for limited government.[497] Americans are extremely charitable by global standards. According to a 2006 British study, Americans gave 1.67% of GDP to charity, more than any other nation studied.[498][499][500]

The American Dream, or the perception that Americans enjoy high social mobility, plays a key role in attracting immigrants.[501] Whether this perception is accurate has been a topic of debate.[502][503][504][505][429][506] While mainstream culture holds that the United States is a classless society,[507] scholars identify significant differences between the country's social classes, affecting socialization, language, and values.[508] While Americans tend to greatly value socioeconomic achievement, being ordinary or average is also generally seen as a positive attribute.[509]

Literature, philosophy, and visual art

In the 18th and early 19th centuries, American art and literature took most of its cues from Europe. Writers such as Washington Irving, Nathaniel Hawthorne, Edgar Allan Poe, and Henry David Thoreau established a distinctive American literary voice by the middle of the 19th century. Mark Twain and poet Walt Whitman were major figures in the century's second half; Emily Dickinson, virtually unknown during her lifetime, is now recognized as an essential American poet.[510] A work seen as capturing fundamental aspects of the national experience and character—such as Herman Melville's Moby-Dick (1851), Twain's The Adventures of Huckleberry Finn (1885), F. Scott Fitzgerald's The Great Gatsby (1925) and Harper Lee's To Kill a Mockingbird (1960)—may be dubbed the "Great American Novel."[511]

Twelve U.S. citizens have won the Nobel Prize in Literature, most recently Bob Dylan in 2016. William Faulkner, Ernest Hemingway and John Steinbeck are often named among the most influential writers of the 20th century.[512] Popular literary genres such as the Western and hardboiled crime fiction developed in the United States. The Beat Generation writers opened up new literary approaches, as have postmodernist authors such as John Barth, Thomas Pynchon, and Don DeLillo.[513]

The transcendentalists, led by Thoreau and Ralph Waldo Emerson, established the first major American philosophical movement. After the Civil War, Charles Sanders Peirce and then William James and John Dewey were leaders in the development of pragmatism. In the 20th century, the work of W. V. O. Quine and Richard Rorty, and later Noam Chomsky, brought analytic philosophy to the fore of American philosophical academia. John Rawls and Robert Nozick also led a revival of political philosophy.

In the visual arts, the Hudson River School was a mid-19th-century movement in the tradition of European naturalism. The 1913 Armory Show in New York City, an exhibition of European modernist art, shocked the public and transformed the U.S. art scene.[514] Georgia O'Keeffe, Marsden Hartley, and others experimented with new, individualistic styles. Major artistic movements such as the abstract expressionism of Jackson Pollock and Willem de Kooning and the pop art of Andy Warhol and Roy Lichtenstein developed largely in the United States. The tide of modernism and then postmodernism has brought fame to American architects such as Frank Lloyd Wright, Philip Johnson, and Frank Gehry.[515] Americans have long been important in the modern artistic medium of photography, with major photographers including Alfred Stieglitz, Edward Steichen, Edward Weston, and Ansel Adams.[516]


Mainstream American cuisine is similar to that in other Western countries. Wheat is the primary cereal grain with about three-quarters of grain products made of wheat flour[517] and many dishes use indigenous ingredients, such as turkey, venison, potatoes, sweet potatoes, corn, squash, and maple syrup which were consumed by Native Americans and early European settlers.[518] These homegrown foods are part of a shared national menu on one of America's most popular holidays, Thanksgiving, when some Americans make traditional foods to celebrate the occasion.[519]

The American fast food industry, the world's largest,[520] pioneered the drive-through format in the 1940s.[521] Characteristic dishes such as apple pie, fried chicken, pizza, hamburgers, and hot dogs derive from the recipes of various immigrants. French fries, Mexican dishes such as burritos and tacos, and pasta dishes freely adapted from Italian sources are widely consumed.[522] Americans drink three times as much coffee as tea.[523] Marketing by U.S. industries is largely responsible for making orange juice and milk ubiquitous breakfast beverages.[524][525]


Although little known at the time, Charles Ives's work of the 1910s established him as the first major U.S. composer in the classical tradition, while experimentalists such as Henry Cowell and John Cage created a distinctive American approach to classical composition. Aaron Copland and George Gershwin developed a new synthesis of popular and classical music.

The rhythmic and lyrical styles of African-American music have deeply influenced American music at large, distinguishing it from European and African traditions. Elements from folk idioms such as the blues and what is now known as old-time music were adopted and transformed into popular genres with global audiences. Jazz was developed by innovators such as Louis Armstrong and Duke Ellington early in the 20th century. Country music developed in the 1920s, and rhythm and blues in the 1940s.[526]

Elvis Presley and Chuck Berry were among the mid-1950s pioneers of rock and roll. Rock bands such as Metallica, the Eagles, and Aerosmith are among the highest grossing in worldwide sales.[527][528][529] In the 1960s, Bob Dylan emerged from the folk revival to become one of America's most celebrated songwriters and James Brown led the development of funk.

More recent American creations include hip hop and house music. American pop stars such as Elvis Presley, Michael Jackson, and Madonna have become global celebrities,[526] as have contemporary musical artists such as Taylor Swift, Britney Spears, Katy Perry, Beyoncé, Jay-Z, Eminem, Kanye West, and Ariana Grande.[530]


Hollywood, a northern district of Los Angeles, California, is one of the leaders in motion picture production.[531] The world's first commercial motion picture exhibition was given in New York City in 1894, using Thomas Edison's Kinetoscope.[532] Since the early 20th century, the U.S. film industry has largely been based in and around Hollywood, although in the 21st century an increasing number of films are not made there, and film companies have been subject to the forces of globalization.[533]

Director D. W. Griffith, the top American filmmaker during the silent film period, was central to the development of film grammar, and producer/entrepreneur Walt Disney was a leader in both animated film and movie merchandising.[534] Directors such as John Ford redefined the image of the American Old West, and, like others such as John Huston, broadened the possibilities of cinema with location shooting. The industry enjoyed its golden years, in what is commonly referred to as the "Golden Age of Hollywood," from the early sound period until the early 1960s,[535] with screen actors such as John Wayne and Marilyn Monroe becoming iconic figures.[536][537] In the 1970s, "New Hollywood" or the "Hollywood Renaissance"[538] was defined by grittier films influenced by French and Italian realist pictures of the post-war period.[539] In more recent times, directors such as Steven Spielberg, George Lucas and James Cameron have gained renown for their blockbuster films, often characterized by high production costs and earnings.

Notable films topping the American Film Institute's AFI 100 list include Orson Welles's Citizen Kane (1941), which is frequently cited as the greatest film of all time,[540][541] Casablanca (1942), The Godfather (1972), Gone with the Wind (1939), Lawrence of Arabia (1962), The Wizard of Oz (1939), The Graduate (1967), On the Waterfront (1954), Schindler's List (1993), Singin' in the Rain (1952), It's a Wonderful Life (1946) and Sunset Boulevard (1950).[542] The Academy Awards, popularly known as the Oscars, have been held annually by the Academy of Motion Picture Arts and Sciences since 1929,[543] and the Golden Globe Awards have been held annually since January 1944.[544]


American football is by several measures the most popular spectator sport;[546] the National Football League (NFL) has the highest average attendance of any sports league in the world, and the Super Bowl is watched by tens of millions globally. Baseball has been regarded as the U.S. national sport since the late 19th century, with Major League Baseball (MLB) being the top league. Basketball and ice hockey are the country's next two leading professional team sports, with the top leagues being the National Basketball Association (NBA) and the National Hockey League (NHL). College football and basketball attract large audiences.[547] In soccer, the country hosted the 1994 FIFA World Cup, the men's national soccer team qualified for ten World Cups and the women's team has won the FIFA Women's World Cup four times; Major League Soccer is the sport's highest league in the United States (featuring 23 American and three Canadian teams). The market for professional sports in the United States is roughly $69 billion, roughly 50% larger than that of all of Europe, the Middle East, and Africa combined.[548]

Eight Olympic Games have taken place in the United States. The 1904 Summer Olympics in St. Louis, Missouri were the first ever Olympic Games held outside of Europe.[549] As of 2017, the United States has won 2,522 medals at the Summer Olympic Games, more than any other country, and 305 in the Winter Olympic Games, the second most behind Norway.[550] While most major U.S. sports such as baseball and American football have evolved out of European practices, basketball, volleyball, skateboarding, and snowboarding are American inventions, some of which have become popular worldwide. Lacrosse and surfing arose from Native American and Native Hawaiian activities that predate Western contact.[551] The most watched individual sports are golf and auto racing, particularly NASCAR.[552][553]

Mass media

The four major broadcasters in the U.S. are the National Broadcasting Company (NBC), Columbia Broadcasting System (CBS), American Broadcasting Company (ABC), and Fox Broadcasting Company (FOX). The four major broadcast television networks are all commercial entities. Cable television offers hundreds of channels catering to a variety of niches.[554] Americans listen to radio programming, also largely commercial, on average just over two-and-a-half hours a day.[555]

In 1998, the number of U.S. commercial radio stations had grown to 4,793 AM stations and 5,662 FM stations. In addition, there are 1,460 public radio stations. Most of these stations are run by universities and public authorities for educational purposes and are financed by public or private funds, subscriptions, and corporate underwriting. Much public-radio broadcasting is supplied by NPR. NPR was incorporated in February 1970 under the Public Broadcasting Act of 1967; its television counterpart, PBS, was created by the same legislation. As of September 30, 2014, there are 15,433 licensed full-power radio stations in the U.S. according to the U.S. Federal Communications Commission (FCC).[556]

Well-known newspapers include The Wall Street Journal, The New York Times, and USA Today.[557] Although the cost of publishing has increased over the years, the price of newspapers has generally remained low, forcing newspapers to rely more on advertising revenue and on articles provided by a major wire service, such as the Associated Press or Reuters, for their national and world coverage. With very few exceptions, all the newspapers in the U.S. are privately owned, either by large chains such as Gannett or McClatchy, which own dozens or even hundreds of newspapers; by small chains that own a handful of papers; or in a situation that is increasingly rare, by individuals or families. Major cities often have "alternative weeklies" to complement the mainstream daily papers, such as New York City's The Village Voice or Los Angeles' LA Weekly. Major cities may also support a local business journal, trade papers relating to local industries, and papers for local ethnic and social groups. Aside from web portals and search engines, the most popular websites are Facebook, YouTube, Wikipedia, Yahoo!, eBay, Amazon, and Twitter.[558]

More than 800 publications are produced in Spanish, the second most commonly used language in the United States behind English.[559][560]

  10. ^ Spain sent several expeditions to Alaska to assert its long-held claim over the Pacific Northwest, which dated back to the 16th century. During the decade 1785–1795 British merchants, encouraged by Sir Joseph Banks and supported by their government, made a sustained attempt to develop this trade despite Spain's claims and navigation rights. The endeavors of these merchants did not last long in the face of Spain's opposition. The challenge was also opposed by a Japanese holding obdurately to national seclusion.[92]
