Native American Population: US Census Data Explained
The Native American population depends on which statistical definition and year you use. In the 2020 US Census, about 3.7 million people identified as American Indian or Alaska Native alone, while about 9.7 million identified as American Indian or Alaska Native alone or in combination with another race. Those are different measures of Census self-identification; neither is a count of enrolled tribal citizens.
2020 Census: two numbers that answer different questions
The Census Bureau reported approximately 3.7 million people in the American Indian and Alaska Native alone category in 2020. When people who selected that category along with one or more additional races are included, the total was about 9.7 million. Combining those figures or describing either one without its definition creates confusion.
The figures also should not be applied automatically to tribal citizenship, eligibility for tribal services, or the population of a particular reservation. Each nation sets its own citizenship rules; the Census records a person's response to a federal survey question.
What more recent estimates can and cannot tell us
The US Census Bureau's American Community Survey offers ongoing estimates, but survey periods, category definitions, and sampling uncertainty mean the results are not identical to the decennial Census count. A 2024 estimate published by the US Department of Health and Human Services describes about 1.7 million non-Hispanic American Indian and Alaska Native people identifying with that race alone; its restricted definition is much narrower than the 2020 'alone or in combination' figure.
When comparing years, first match race and Hispanic-origin definitions, decide whether you are using survey estimates or a Census enumeration, and display the publication year. Do not call a smaller restricted estimate evidence of a population collapse.
Why identity and citizenship differ
A Census race response is self-reported. Tribal citizenship is a political and legal relationship governed by the specific tribal nation. Some people identify with more than one racial group, and some Alaska Native corporations, villages, and tribal nations have administrative structures that cannot be reduced to one column in a national spreadsheet.
Researchers should avoid treating the total count of federally recognized tribes as a number of people, or assuming that every person in a self-reported race category is a citizen of one of those nations.
Geography and state comparisons
American Indian and Alaska Native people live in every state. Depending on whether the measure is percentage share or total headcount, different states lead the rankings. Alaska and New Mexico have high proportions under some categories; large-population states such as California can have high absolute counts. A reservation map cannot substitute for Census data on where people actually live.
Use geographic boundaries and table footnotes carefully: metropolitan areas, counties, reservations, and tribal statistical areas are not interchangeable units.
A responsible way to cite population statistics
For every number, write the source, census or survey year, exact racial category, whether Hispanic origin is included, geographic coverage, and whether the result is an estimate. For comparisons across time, check changes in question design or response coding. This level of detail helps explain apparent disagreements among otherwise reliable government websites.

Frequently asked questions
How many Native Americans were counted in the 2020 Census?
About 9.7 million identified as American Indian or Alaska Native alone or with another race; about 3.7 million used the category alone.
Does the Census number equal tribal membership?
No. Self-reported race and enrollment under a tribal nation’s laws are different measures.
Why do some government sources show a lower number?
They may use a different year, survey, Hispanic-origin filter, or the AI/AN-alone category rather than alone-or-in-combination.
Do Native American people live only on reservations?
No. Native communities include urban, suburban, rural, and reservation residents throughout the United States.
