Race and ethnicity in the United States

Social definitions of race

Since the concept of race became widespread in the early United States, people of Native American heritage, African heritage, and European heritage were considered to belong to different races. For nearly three centuries, the criteria for membership in these groups were similar; a person's appearance, their social circle (how they lived), and ancestry were all considered by society when determining someone's race.

The motivations behind historical definitions of racial identity, especially Native American and black identities, have been the topic of much discussion in modern years. According to many anthropologists, these racial designations were a means to concentrate power, wealth, privilege and land in the hands of white people in a society of white hegemony and privilege. Racial distinctions generally had little to do with biology and more to do with the history of slavery, the systemic racism it produced, and specific forms of white supremacy that benefited from specific definitions of racial identity. For example, it has been suggested that the blood quantum laws defining Native American identity enabled whites to acquire indigenous lands during the allotment process, and the one-drop rule of black identity, enforced legally in the early 20th century, enabled them to preserve their agricultural labor force in the South.

The descendants of Native and Black Americans not only had to contend with laws defining their racial identity for the benefit of the majority, but also with a variety of social consequences depending on how they were perceived in society. Compared to other mixed Americans, the blood quantum laws made it easier for a person of mixed European and Native American ancestry to be accepted as white; after a few generations of intermarriage, the offspring of Native and White Americans would no longer legally be considered Native American. They could have treaty rights to land, but because an individual with only one native great-grandparent no longer was classified as Native American, they lost legal claim to their land under historical allotment rules, making it easier for White Americans to acquire the land for their own development. On the other hand, the same individual who could be denied legal standing in a tribe because he was "too White" to claim property rights might still have enough visually identifiable native ancestry to be considered socially as a "half-breed" and stigmatized by both communities.

The 20th-century one-drop rule made it relatively difficult for anyone of known black ancestry to be accepted as white. The child of a black sharecropper and a white person was considered black by the local communities, and would likely become a sharecropper as well, thus adding to the landholder or employer's labor force. Because the agricultural economy of the time benefited from using Black Americans as a labor force, it was advantageous for as many people as possible to be defined as black. Many experts on the Jim Crow period agree that the 20th century notion of invisible blackness shifted the color line in the direction of paleness, and "expanded" the labor force in response to Southern blacks' Great Migration to the North, although others (such as the historians C. Vann Woodward, George M. Fredrickson, and Stetson Kennedy) considered the one-drop rule a consequence of the need to justify the oppression of Black Americans and define whiteness as pure.

Over the centuries, as whites wielded social and political power over people of color in the United States, they created a social order of hypodescent, in which they assigned mixed-race children to the lower-status groups. However, they were often ignorant of the systems of social classification within Native American tribes. The Omaha people, for instance, who had a patrilineal kinship system, classified all children with white fathers as "White", and excluded them as members of the tribe unless they were formally adopted by a male member. Tribal members might care for mixed-race children of White fathers, but they were considered outside the hereditary clan and kinship fundamental to tribal society.

The social construction of hypodescent also related to the racial caste system associated with slavery. It was made explicit by Virginia and other colonies' laws as early as 1662. Virginia incorporated the Roman principle of partus sequitur ventrem into slave law, saying that children of enslaved mothers were born into slavery as well. Under English common law, children's social status was determined by the father, not the mother, but the colonists considered enslaved Africans outside the category of English subjects. Although White men were in positions of power to take sexual advantage of enslaved black women, this meant that their offspring would be considered Black and were enslaved regardless of their parentage. However, most free Black American families listed in the censuses of 1790–1810 were descended from unions between White women and African men in colonial Virginia, from the years when working classes lived and worked closely together, and before slavery had hardened as a racial caste.

In the United States, social and legal conventions developed over time by Whites classified individuals of mixed ancestry into simplified racial categories, but these were always flawed. The decennial censuses conducted since 1790, after slavery was well established in the United States, included a classification of persons by race, with the categories of "White", "Black", "Mulatto", and "Indian". The inclusion of mulatto was a rare explicit acknowledgement of mixed-race people, but that status was usually simplified into one race or another in actual society. Before the Civil War, states such as Virginia had a legal definition of whiteness that classified people as white if they were no more than 1/8th black. For example, if not born into slavery, Thomas Jefferson's children by his slave Sally Hemings would have been classified as legally white, as they were 7/8ths White by ancestry. Three of the four surviving children entered white society as adults, and their descendants have identified as white. In the late 18th and 19th centuries, people of mixed race often migrated to frontiers where societies were more open, and they might be accepted as white if they satisfied obligations of citizenship.

The more familiar "one-drop rule" was not adopted by Virginia and other states until the 20th century, but it classified persons with any known African ancestry as black. Passage of these laws was often encouraged by white supremacists and people promoting "racial purity", who disregarded the long history of multi-racial unions in the South. In other countries in the Americas, where mixing among groups was overtly more extensive, social categories have tended to be more numerous and fluid. In some cases, people may move into or out of categories on the basis of a combination of socioeconomic status, social class, ancestry, and appearance.

The term Hispanic as an ethnonym emerged in the 20th century, with the rise of migration of laborers from Spanish-speaking countries of the western hemisphere to the United States. It includes people who may have been considered racially distinct (black, white, native, or other mixed groups) in their home countries. Today, the word "Latino" is often used as a synonym for "Hispanic". Even if such categories were earlier understood as racial categories, today they have begun to represent ethnolinguistic categories, regardless of perceived race. Similarly, the prefix "Anglo" is now used among some Hispanics to refer to non-Hispanic White Americans or European Americans, most of whom speak the English language but are not of primarily English descent. A similar phenomenon of ethnolinguistic identity can historically (and in some cases contemporarily) be seen in the case of the Louisiana Creole people, who may be of any race but share certain cultural characteristics. Over time the mix of cultures blending, migration, and changes in ideas related to identity led to a diverse society. Group boundaries are becoming less fixed, but more openly debated in schools, daily lives, and government discussions.

Historical trends and influences

The growth of the Hispanic population through immigration and high birth rates is noted as a partial factor for US population gains in the last quarter-century. The 2000 census revealed that Native Americans had reached their highest documented population, 4.5 million, since the US was founded in 1776. In some cases, immigrants and migrants have formed ethnic enclaves; in others, this mixture of races has created ethnically diverse communities. Earlier immigrants to the Americas came from widely separated regions of Afro-Eurasia, and American immigrant populations frequently mixed among themselves and with the indigenous inhabitants of the continents, creating a complex multiracial population.

Throughout American history, efforts to classify the increasingly mixed population of the United States into discrete categories have generated many difficulties. "Discussions about race and racism are often highly emotional and encompass a wide range of emotions, including discomfort, fear, defensiveness, anger, and insecurity." Early efforts to track mixing between groups led to a proliferation of historical categories (such as "mulatto" and "octaroon" among persons with partial African descent) and "blood quantum" distinctions, which became increasingly detached from self-reported ancestry. By the standards used in early censuses, many mixed-race children born in the US were classified as of a different race than one of their biological parents, and even when these standards were no longer commonly accepted, the combination of social perceptions of race and self-identification with a racial identity frequently complicated legal standards of racial identity. Even people who did not identify as mixed faced the issue of unclear legal terminology; until the 2000 census, Hispanic Americans were required to identify as one race on censuses, and without the option to select Latino or Hispanic, confusion flourished.

Historical trends influencing the ethnic demographics of the United States include:

• Patterns of original settlement
  • Settlement of the Americas by Native American First Nations and Alaska Native peoples in several waves over thousands of years, beginning at least 15,000 years ago
  • Settlement of Pacific islands by Polynesian people, including Native Hawaiians, Samoans in American Samoa, and the Chamorros in Guam and the Northern Mariana Islands
  • Settlement of the Antilles, including the US Virgin Islands and Puerto Rico, by the "Ortoiroid" people, and later by the Arawak-speaking ancestors of the Taíno, Ciboney, and Kalinago people
• Colonization
  • Spanish colonization of the Americas, including Florida, the Southwest, and Puerto Rico, which are all today considered part of the United States
  • French colonization of the Americas, including the Old Northwest and the lower Mississippi River; historical events, including the Expulsion of the Acadians, influenced the ethnic mix, especially in Louisiana, northern New England, and New York
  • Dutch colonization of the Americas, mainly of the Hudson River
  • British colonization of the Americas, beginning with Caribbean and the Thirteen Colonies
  • Danish colonization of the Americas, including what is now known as the United States Virgin Islands
• Penal transportation to the Americas of felons under British rule
• The popularity of indentured servitude, usually from Ireland, until the late 18th century
• The Atlantic slave trade, which brought millions of Africans to the South, Caribbean, and Latin America
• Severe reduction of Native American populations in the contiguous United States, largely due to new infectious diseases carried by European colonists combined with genocidal warfare
• Forced migration
  • Deportation and flight of United Empire Loyalists to Canada, the Caribbean, and Britain after the American Revolution
  • Forced removal of more than one million African Americans in the domestic slave trade from the Upper South to the Deep South during the early 19th century as Americans developed new lands for plantations
  • Territorial conflict with Native Americans and the Indian removal policy of the 19th century displaced many remaining native populations from east of the Mississippi River to territories to the west, especially to what is now Oklahoma
• Immigration
  • Historical immigration to the United States from all countries of the world for religious, political and economic reasons, influenced by laws concerning immigration and naturalization in the United States and illegal immigration to the United States, which denied various entry due to discrimination, economic protectionism, and political conflict with their nation of origin
  • Transatlantic migrations from Europe, especially in the 19th century, which created ethnic enclaves in many eastern cities and settling many rural areas east of the Mississippi
  • Immigration from Asia, which has had the most influence on Hawaii and the West Coast
  • Immigration from Mexico and Latin America, which has strongly influenced the Southwest
• Westward expansion of the United States
  • The Royal Proclamation of 1763, which restricted the western boundary of European settlement to the watershed east of the Appalachian Mountains
  • The Homestead Act, which promoted settlement west of the Mississippi after the Louisiana Purchase
  • Settlement of Utah by members of the Church of Jesus Christ of Latter-day Saints
  • California gold rush
  • Oregon Trail
  • The Klondike gold rush, which promoted settlement of Alaska
• Internal migration
  • African Americans escaping from slavery prior to the Civil War, sometimes via the Underground Railroad, and reaching the free North
  • The American Industrial Revolution, which promoted urbanization of what was previously a largely agrarian society
  • Improved transportation systems increasing the ease of American migration through the country
  • The Great Migration and Second Great Migration, in which Black Americans moved to Northern, Midwestern, and Western cities in order to seek economic opportunity and escape racial violence
  • Railroads, promoting migration westwards and streetcar suburbs, which created significant ethnic shifts in urban areas
  • Natural disasters such as the Dust Bowl
  • The suburbanization period after World War II, which produced "white flight" to new housing and away from social unrest, followed by "black flight"
  • The development of air conditioning, which encouraged migration from northern areas to the Sun Belt

Racial and ethnic makeup of the US population

For demographics by specific ethnic groups rather than general race, see "Ancestry" below.

White and European Americans

White and European Americans are the majority of people living in the United States. White people are defined by the United States Census Bureau as those "having origins in any of the original peoples of Europe, the Middle East, or North Africa". Like all official US racial categories, "White" has a "not Hispanic or Latino" and a "Hispanic or Latino" component, the latter consisting mostly of Spanish Americans, White Mexican Americans, and White Cuban Americans.

As of 2022, White Americans are the majority in every census-defined region (Northeast, Midwest, South, and West) and 44 out of 50 states. White Americans of one race are not a majority in the states of Hawaii, California, Texas, New Mexico, Nevada, and Maryland, along with the District of Columbia, American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the US Virgin Islands. However, those identifying as White alone or in combination (including multiracial White Americans) are the majority in every state except for Hawaii, along with being a majority in the territory of Puerto Rico. As of the 2020 US census, non-Hispanic Whites are a majority in 44 states, excluding California, Hawaii, Maryland, Nevada, New Mexico, Texas, the District of Columbia, American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the US Virgin Islands.

The non-Hispanic White percentage of the 50 states and District of Columbia (60.1% in 2019) has been decreasing since the mid-20th century as a result of changes made in immigration policy, most notably the Hart–Celler Act of 1965. If current trends continue, non-Hispanic Whites will drop below 50% of the overall US population by 2050. White Americans overall (non-Hispanic Whites together with White Hispanics, along with many of those identified as "some other race" who are reclassified as White for Census Bureau projections, as this category is not recognized by the Office of Management and Budget) are projected to continue as the majority, at 72.6% (or 264 million out of 364 million) in 2060, from currently 75.5%.

Although a high proportion of the population is known to have multiple ancestries, in the 2020 United States census, most people still identified with one racial category. In the 2020 census, self-identified English Americans made up 46.6 million of the US population, followed by German Americans at 45 million, as reported in the 2020 census. This makes English and German the largest and second-largest self-reported ancestry groups in the United States. Many English Americans and other British Americans self-identified under the category entry "American", thus considering themselves indigenous because their families had resided in the US for so long. 17.8 million Americans listed their ancestry as "American" on the 2020 census (see American ancestry).

Most French Americans are believed to be descended from colonists of Catholic New France; exiled Huguenots, much fewer in number and settling in the eastern English colonies in the late 1600s and early 1700s, needed to assimilate into the majority culture and have intermarried over generations. Some Louisiana Creoles, including the Isleños of Louisiana, and the Hispanos of the Southwest have had, in part, direct Spanish ancestry; most self-reported White Hispanics are of Mexican, Puerto Rican, Cuban, and Salvadoran origins, each of which are multi-ethnic nations. Hispanic immigration has increased from nations of Central and South America.

There are a substantial number of White Americans who are of Eastern and Southern European descent, such as Russian, Polish, Italian, and Greek Americans. Eastern Europeans immigrated to the United States more recently than Western Europeans. Arabs, Armenians, Iranians, Israelis, Turks and other West Asians, are reported as White in the United States census, as a result of a federal court case from 1909, even though most do not identify as White. The new classification, which will come into effect with 2030 United States census, will only include Armenians, Azerbaijanis, Georgians and Turks in the 'White' classification while the other Western Asian ancestries will be falling under the 'Middle Eastern' category.

Hispanic and Latino Americans

Hispanic or Latino Population by race (2020):

Hispanic or Latino Americans number 59.8 million people, or 18.3% of the total US population as of 2018. The category includes people who are of full or partial Hispanic or Latino origin. They typically have origins in the Spanish-speaking nations of Latin America, although a few also come from other places (0.2% of Hispanic and Latino Americans were born in Asia, for example). The group is heterogeneous in race and national ancestry.

The Census Bureau defines "Hispanic or Latino origin" thus:

For Census 2000, American Community Survey: People who identify with the terms "Hispanic" or "Latino" are those who classify themselves in one of the specific Hispanic or Latino categories listed on the Census 2000 or ACS questionnaire ("Mexican," "Puerto Rican," or "Cuban") as well as those who indicate that they are "other Spanish, Hispanic, or Latino". Origin can be viewed as the heritage, nationality group, lineage, or country of birth of the person, or the person's parents or ancestors, before their arrival in the United States. People who identify their origin as Spanish, Hispanic, or Latino may be of any race.

Per the 2019 American Community Survey, the leading ancestries for Hispanic Americans are Mexican (37.2 million) followed by Puerto Rican (5.83 million), Cuban (2.38 million), and Salvadoran (2.31 million). In addition, there are 3.19 million people living in Puerto Rico who are excluded from the count (see Puerto Ricans).

The Hispanic and Latino population in the United States has reached 58 million as of 2016, and has been the principal driver of United States demographic growth since 2000. Mexicans make up most of the Hispanic and Latino population at 35,758,000. The United States also has large Dominican, Guatemalan, Colombian, Honduran, Spanish, Ecuadorian, Peruvian, Salvadoran, Nicaraguan, Venezuelan and Panamanian populations. The population of Hispanic Americans that has received a college education is also growing; in 2015, 40% of Hispanic Americans age 25 and older have had a college experience, but in 2000, the percentage was at a low 30%. Among US states, California houses the largest population of Latinos. In 2019, 15.56 million lived in California. As of 2019, the US territory with the largest percentage of Hispanics/Latinos is Puerto Rico (98.9% Hispanic or Latino).

The Hispanic or Latino population is young and fast-growing, due to immigration and higher birth rates. For decades it has contributed significantly to US population increases, and this is expected to continue. The Census Bureau projects that by 2050, one-quarter of the population will be Hispanic or Latino.

Black and African Americans

African Americans, or Black Americans, are citizens of the United States with African ancestry. According to the Office of Management and Budget, the grouping includes individuals who self-identify as African American and are descended from Africans that were forcibly relocated to the United States and enslaved, as well as those who recently and voluntarily emigrated from nations in the Caribbean and sub-Saharan Africa. Both groups of people may also identify as Black or some other written-in race. However, some immigrants from the continent of Africa do not identify as Black and are not socially perceived as such, such as the Afrikaners of South Africa. According to the 2009 American Community Survey, there were 38,093,725 Black and African Americans in the United States, representing 12.4% of the population. There were 37,144,530 non-Hispanic Blacks, which comprised 12.1% of the population. According to the 2010 US census, this number increased to 42 million when including multiracial African Americans, making up 13% of the total US population. African Americans make up the second largest group in the United States, but the third largest group after White Americans and Hispanic or Latino Americans of any race. The majority of the population (55%) lives in the South, and there has been a decrease of African Americans in the Northeast and Midwest. The US state/territory with the highest percentage of African Americans is the US Virgin Islands (76% African American as of 2010).

Most African Americans are the direct descendants of captives from West Africa, who survived the slavery era within the boundaries of the present United States. The first West Africans were brought to Jamestown, Virginia in 1619. The English settlers treated these captives as indentured servants and released them after a number of years. This practice was gradually replaced by the system of race-based slavery used in the Caribbean. All the American colonies had slavery, but it was usually in the form of personal servants in the North (where 2% of the population were enslaved), and field hands in plantations in the South (where 25% were enslaved); by the beginning of the American Revolutionary War, a fifth of the total population was enslaved. During the revolution, some served in the Continental Army or Continental Navy, while others fought for the British Empire in units such as the Ethiopian Regiment. By 1804, the states north of the Mason–Dixon line had abolished slavery. However, slavery would persist in the Southern states until the end of the American Civil War and the passage of the Thirteenth Amendment. Following the end of the Reconstruction era, which saw the first African American representation in Congress, African Americans became disenfranchised and subject to Jim Crow laws, legislation that would persist until the passage of the Civil Rights Act of 1964 and Voting Rights Act of 1965 due to the civil rights movement.

According to US Census Bureau data, very few African immigrants self-identify as "African-American" (as "African-American" is usually referring to Blacks with deeply rooted ancestry dating back to the US slave period as discussed in the previous paragraph.) On average, less than 5% of African residents self-reported as "African-American" or "Afro-American" in the 2000 US census. The overwhelming majority of African immigrants (~95%) identified instead with their own respective ethnicities. Self-designation as "African-American" or "Afro-American" was highest among individuals from West Africa (4–9%), and lowest among individuals from Cape Verde, East Africa, and Southern Africa (0–4%). Nonetheless, African immigrants often develop very successful professional and business working-relationships with African Americans. Immigrants from some Caribbean, Central American, and South American nations and their descendants may or may not also self-identify with the term "African American".

Recent African immigrants in the United States come from countries such as Jamaica, Haiti, Nigeria, Ethiopia, Dominican Republic, Ghana, Trinidad and Tobago, Kenya, Guyana, and Somalia.

Asian Americans

A third significant minority is the Asian American population, which comprised 19.36 million people, or 5.9% of the US population, in 2019. In 2019, 6.12 million Asian Americans lived in California. As of 2019, approximately 532,300 Asians live in Hawaii, forming 37.6% of the islands' people. This makes Hawaii the state with the highest percentage of Asian Americans. Although they were historically first concentrated in Hawaii and the West Coast, Asian Americans now live across the country, living and working in large numbers in New York City, Chicago, Boston, Houston, and other major urban centers. There are also many Asians living in two Pacific US territories (Guam and the Northern Mariana Islands) – as of 2010, Guam's population was 32.2% Asian, and the population of the Northern Mariana Islands was 49.9% Asian.

Filipinos have been in the territories that would become the United States since the 16th century. In 1635, an "East Indian" is listed in Jamestown, Virginia; preceding wider settlement of Indian immigrants on the East Coast in the 1790s and the West Coast in the 1800s. In 1763, Filipinos established the small settlement of Saint Malo, Louisiana, after fleeing mistreatment aboard Spanish ships. Since there were no Filipino women with them, these "Manilamen", as they were known, married Cajun and indigenous women. The first Japanese person to come to the United States, and stay any significant period of time was Nakahama Manjirō who reached the East Coast in 1841, and Joseph Heco became the first Japanese American naturalized US citizen in 1858. As with the new immigration from central and eastern Europe to the East Coast from the mid-19th century on, Asians started immigrating to the United States in large numbers in the 19th century. This first major wave of immigration consisted predominantly of Chinese and Japanese laborers, but also included Korean and South Asian immigrants. Many immigrants also came during and after this period from the Philippines, which was a US colony from 1898 to 1946. Exclusion laws and policies largely prohibited and curtailed Asian immigration until the 1940s. After the US changed its immigration laws during the 1940s to 1960s to make entry easier, a much larger new wave of immigration from Asia began. Today, the largest self-identified Asian American sub-groups, according to census data, are Chinese Americans, Filipino Americans, Indian Americans, Vietnamese Americans, Korean Americans, and Japanese Americans, among other groups.

Not all of Asian Americans' ancestors directly migrated from their country of origin to the US. For example, more than 270,000 people from Guyana, a South American country, reside in the US, but a predominant number of Guyanese people are of Indian descent.

Middle Eastern and North African Americans

Middle Eastern Americans and North African Americans are Americans with ancestry from the Middle East and North Africa (MENA). There are an estimated 3.5 million Middle Eastern Americans according to the US Census Bureau in 2020 comprising 1.06% of the population and including both Arab and non-Arab Americans. The Arab American Institute in 2014 estimated a population of 3.6 million. US census population estimates are based on responses to the ancestry question on the census, which makes it difficult to accurately count Middle Eastern Americans. Though Middle Eastern American communities can be found in each of the 50 states, the majority live in just 10 states; nearly a third live in California, New York, and Michigan. More Middle Eastern Americans live in California than any other state, with ethnic groups such as Arabs and Persians being a large percentage, but Middle Eastern Americans represent the highest percentage of the population of Michigan. In particular, Dearborn, Michigan has long been home to a high concentration of Middle Eastern Americans.

The US Census Bureau is still finalizing the ethnic classification of MENA populations. Middle Eastern Americans are currently counted as racially White on the census, although many do not identify as such. In 2012, prompted in part by post-9/11 discrimination, the American-Arab Anti-Discrimination Committee petitioned the Department of Commerce's Minority Business Development Agency to designate the MENA populations as a minority/disadvantaged community. Following consultations with MENA organizations, the US Census Bureau announced in 2014 that it would establish a new MENA ethnic category for populations from the Middle East, North Africa, and the Arab world, separate from the "white" classification that these populations had previously sought in 1909. The expert groups felt that the earlier "White" designation no longer accurately represents MENA identity, so they successfully lobbied for a distinct categorization. This process does not currently include ethnoreligious groups such as Sikhs, as the Bureau only tabulates these groups as followers of religions rather than members of ethnic groups.

According to the Arab American Institute, countries of origin for Arab Americans include Algeria, Bahrain, Egypt, Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Qatar, Palestine, Saudi Arabia, Syria, Tunisia, United Arab Emirates, and Yemen. As of December 2015, the sampling strata for the new MENA category includes the Census Bureau's working classification of 19 MENA groups, as well as Afghan, Iranian, Israeli, and Azerbaijani groups. The new category will identify "Israeli" as a choice and raises questions as to how the large US Jewish population (7-8 million) will identify.

The new question on the US census will identify the MENA category to include:

"Individuals with origins in any of the original peoples of the Middle East or North Africa, including, for example, Lebanese, Iranian, Egyptian, Syrian, Iraqi, and Israeli."

Native Americans and Alaska Natives

Indigenous peoples of the Americas, particularly Native Americans, made up 1.1% of the population in 2020, numbering 3.7 million. An additional 5.9 million persons declared part-American Indian or Alaska Native ancestry, totaling 2.9% of the population. Levels of Native American ancestry (distinct from Native American identity) differ. According to a study using data from 23andMe customers, genomes of self-reported African Americans averaged to 0.8% Native American ancestry, those of European Americans averaged to 0.18%, and those of Latinos averaged to 18.0%. Among the Hispanic population, numbering over 60 million in total, a genetic study from 2018 has found an average of 38% Native American ancestry, 1% African Americans, and 0.1% European Americans.

The legal and official designation of who is Native American has aroused controversy by demographers, tribal nations, and government officials for many decades. Federally recognized tribes and state recognized tribes set their own membership requirements; tribal enrollment may require residency on a reservation, documented lineal descent from recognized records, such as the Dawes Rolls, and other criteria. Some tribes have adopted the use of blood quantum, requiring members to have a certain percentage. The federal government requires individuals to certify documented blood quantum of ancestry for certain federal programs, such as education benefits, available to members of recognized tribes. Census takers accept any respondent's identification. Genetic scientists estimate that millions of other Americans, including some African Americans and many Hispanic Americans (especially those of Mexican heritage), may have significant Native ancestry.

Once thought to face extinction as a race or culture, Native Americans of numerous tribes have achieved revival of aspects of their cultures, and have fought to retain sovereignty and control of their own affairs for centuries. In recent years, many have started language programs to revive use of traditional languages, established tribally controlled colleges and other schools on their reservations, and developed gaming casinos on their sovereign land to raise revenues for economic development, as well as to promote the education and welfare of their people through health care and construction of improved housing.

Today, more than 800,000 to one million persons claim Cherokee descent in part or as full-bloods; of these, an estimated 300,000 live in California, 160,000 in Oklahoma (of which a majority are Cherokee Nation citizens), and 15,000 in North Carolina, living in ancestral homelands as members of the Eastern Band of Cherokee Indians.

The second largest tribal group is the Navajo, who call themselves Diné and live on a 16‑million-acre Indian reservation covering northeast Arizona, northwest New Mexico, and southeast Utah. It is home to half of the 450,000 members of the Navajo Nation. The third largest group are the Lakota (Sioux) Nation, with distinct federally recognized tribes located in the states of Minnesota, Nebraska, Montana, Wyoming; and North and South Dakota.

As of the 2020 census, the largest self-identified Native American group not combined with another race is Aztec, numbering 378,122 individuals. Though Aztecs are indigenous to Mexico and not the United States, they are nevertheless considered Native American people per census guidelines, which includes any indigenous people from the Americas. Of the 3.2 million Americans who identified as American Indian or Alaska Native alone in 2022, around 45% are of Hispanic or Latino ethnicity, with this number growing as increasing numbers of Indigenous people from Latin American countries immigrate to the US and more Latinos self-identify with indigenous heritage.

Native Hawaiians and other Pacific Islanders Americans

Native Hawaiians and other Pacific Islanders numbered approximately 656,400 in 2019, or 0.2% of the population. Additionally, nearly as many individuals identify themselves as having partial Native Hawaiian ancestry, for a total of 829,949 people of full or part Native Hawaiian ancestry. This group constitutes the smallest minority in the United States. More than half identify as "full-blooded", but historically most Native Hawaiians on the island chain of Hawaii are believed to have some Asian and European ancestry.

Some demographers believe that by 2025, the last full-blooded Native Hawaiian will die off, leaving a culturally distinct but racially mixed population. However, throughout Hawaii, they are working to preserve and assert adaptation of Native Hawaiian customs and the Hawaiian language by establishing cultural schools solely for legally Native Hawaiian students and more.

There are significant Pacific Islander populations living in three Pacific US territories (American Samoa, Guam, and the Northern Mariana Islands). As of 2010, American Samoa's population was 92.6% Pacific Islander (mostly Samoan), Guam's population was 49.3% Pacific Islander (mostly Chamorro), and the population of the Northern Mariana Islands was 34.9% Pacific Islander. Out of all US states/territories, American Samoa has the highest percentage of Pacific Islanders.

Two or more races

Self-identified multiracial Americans numbered 7.0 million in 2008, or 2.3% of the population. They have identified as any combination of races (White, Black or African American, Asian, American Indian or Alaska Native, Native Hawaiian or other Pacific Islander, and "some other race") and ethnicities. The US has a growing multiracial identity movement.

While the colonies and southern states protected White fathers by making all children born to slave mothers be classified as slaves, regardless of paternity, they also banned miscegenation or interracial marriage, most notably between Whites and Blacks. However, this did little to stop interracial relationships. Demographers state that, due to new waves of immigration, the American people through the early 20th century were mostly multi-ethnic descendants of various immigrant nationalities, who maintained cultural distinctiveness until, over time, assimilation, migration and integration took place. The civil rights movement through the 20th century gained passage of important legislation to enforce constitutional rights of minorities, including multiracial Americans.

The multiracial population that is part White is the largest percentage of the multiracial population. As of the 2000 census, 7,015,017 people self-identified as White/American Indian and Alaskan Native, 737,492 as White/Black, 727,197 as White/Asian, and 125,628 as White/Native Hawaiian and Pacific Islander.

Genetic admixture

A 2002 study found an average of 18.6% European genetic contribution and 2.7% Native American genetic contribution (with standard errors of 1.5% and 1.4% respectively) in a sample of 232 African Americans. Meanwhile, in a sample of 187 European Americans from State College, Pennsylvania, there was an average of 0.7% West African genetic contribution and 3.2% Native American genetic contribution (with standard errors of 0.9% and 1.6% respectively). Most of the non-European admixture was concentrated in 30% of the sample, with West African admixture ranging from 2 to 20% with an average of 2.3%.

In 1958, Robert Stuckert produced a statistical analysis using historical census data and immigration statistics. He concluded that the growth in the White population could not be attributed solely to births in the White population and immigration from Europe, but was also due to people identifying as White who were partly Black. He concluded that 21% of White Americans had some recent African-American ancestors and that the majority of Americans of known African descent were partly European and not entirely sub-Saharan African.

More recently, many different DNA studies have shown that many African Americans have European admixture, reflecting the long history in this country of the various populations. Proportions of European admixture in African-American DNA have been found in studies to be 17% and between 10.6% and 22.5%. Another recent study found the average to be 21.2%, with a standard error of 1.2%.

The Race, Ethnicity, and Genetics Working Group of the National Human Genome Research Institute notes that "although genetic analyses of large numbers of loci can produce estimates of the percentage of a person's ancestors coming from various continental populations, these estimates may assume a false distinctiveness of the parental populations, since human groups have exchanged mates from local to continental scales throughout history."

Members of other races

In the 2000 census, the non-standard category of "Other" was especially intended to capture responses such as mestizo and mulatto, two large multiracial groups in most of the countries of origin of Hispanic and Latino Americans. However, many other responses are captured by the category.

In 2008, 15 million people, nearly five percent of the total US population, were estimated to be "some other race", with 95% of them being Hispanic or Latino.

Due to this category's non-standard status, statistics from government agencies other than the Census Bureau (for example, the Centers for Disease Control's data on vital statistics, or the FBI's crime statistics), but also the Bureau's own official Population Estimates, omit the "some other race" category and include most of the people in this group in the White population, thus including the vast majority (about 90%) of Hispanic and Latino Americans in the White population.

Ancestry

The ancestry of the people of the United States is widely varied and includes descendants of populations from around the world. In addition to its variation, the ancestry of people in the United States is also marked by varying amounts of intermarriage between ethnic and racial groups.

While some Americans can trace their ancestry back to a single ethnic group or population in Europe, Africa, or Asia, these are often first, second and third-generation Americans. Generally, the degree of mixed heritage increases the longer people's ancestors have lived in the United States (see melting pot). There are several means available to discover the ancestry of the people living in the United States, including genealogy, genetics, oral and written history, and analysis of Federal Population Census schedules; in practice, only few of these have been used for a larger part of the population.

2022 American Community Survey

This table displays all self-reported ancestries with over 50,000 members, alone or in combination, according to estimates from the 2022 American Community Survey. The total population of the US according to the survey was 333,287,550, and 251,732,240 people reported an ancestry. Of these, 175,054,020 reported a single ancestry, and 76,678,224 reported two or more ancestries. Hispanic groups are not distinguished between total and partial ancestry

However, demographers regard the reported number of English Americans as a statistical error, as the index of inconsistency is high and many, if not most, Americans from English stock have a tendency to identify simply as Americans, or, if of mixed European ancestry, with a different European ethnic group.
