Native American Identity: Definition, Terminology & Citizenship

When someone asks what it means to be Native American, the answer often depends on who you ask — and what day it is, with more than 9 million people in the United States identifying as American Indian or Alaska Native across 574 federally recognized tribes each with their own membership rules. This guide walks through the legal definitions, cultural dimensions, and shifting terminology that shape Native American identity today.

AIAN population alone (2020 Census): 3.7 million ·
Federally recognized tribes: 574 ·
Year term “Native American” popularized: 1960s ·
Indian Citizenship Act: 1924

Five data points, one pattern: legal and cultural definitions of Native American identity are layered, often overlapping but never interchangeable.

What is considered to be Native American?

Legal definitions: tribal enrollment and federal recognition

• Federal recognition by the Bureau of Indian Affairs (BIA, federal agency – see card 1) confers specific legal status, including eligibility for certain federal services.
• Tribal nations set their own enrollment criteria — some use blood quantum minimums, others require lineal descent from historical rolls (California Law Review – see card 2).
• The U.S. Census Bureau (Parent Center Hub) defines American Indian or Alaska Native as “a person having origins in any of the original peoples of North and South America and who maintains tribal affiliation or community attachment.”

Self-identification alone does not create legal Native American status. In practice, the federal government and tribes use a mix of blood quantum, lineage, and community membership — and those criteria are not always aligned.

Cultural and self-identification aspects

• The American Declaration on the Rights of Indigenous Peoples (Organization of American States) states that self-identification is a fundamental criterion for determining to whom the declaration applies.
• Many Native people consider culture, language, and community recognition as central to identity beyond any legal paperwork (Native Philanthropy – see card 1).

The role of blood quantum

• Blood quantum is a colonial-era concept that measures ancestry in fractions (e.g., 1/4, 1/2). The California Law Review (see card 2) notes that many federal definitions historically required blood quantum, and many tribes adopted similar criteria.
• The BIA issues a Certificate of Degree of Indian Blood (CDIB) used for enrollment and federal services, though each tribe decides its own minimum threshold.

Is Native American the same as Indian?

History of the term “Indian” and its origins

• Christopher Columbus used the term “Indios” in 1492, mistakenly believing he had reached the Indies. The name stuck for centuries (Smithsonian Institution – see card 3).
• “American Indian” remains the standard term in U.S. law — for example, the Indian Child Welfare Act (ICWA) uses it.

The shift to “Native American” in the 1960s

• In the 1960s, the term “Native American” gained traction as a more respectful and accurate descriptor, emphasizing that Indigenous peoples were here first (Native Philanthropy – see card 1).
• The Parent Center Hub terminology guide (see above) notes that “American Indian” usually refers to Indigenous peoples of the contiguous U.S. and often excludes Alaska Natives and Native Hawaiians.

Preferred terminology by tribal communities

• Many individuals prefer to be identified by their specific tribal affiliation (e.g., Navajo, Cherokee, Inuit) rather than by pan-ethnic labels (Native American Rights Fund – see card 1).
• The U.S. Census Bureau (see card 2) uses “American Indian and Alaska Native” as its official category.

Let’s compare the three umbrella terms side by side.

What is the closest DNA to Native Americans?

Genetic studies linking Native Americans to ancient Siberians

• Indigenous Americans share the closest genetic affinity with ancient populations from Siberia, according to research published in Nature.
• This analysis shows that the ancestors of modern Native Americans migrated across the Bering land bridge more than 15,000 years ago.

The role of the Bering land bridge

• During the last Ice Age, lower sea levels exposed a land connection between Siberia and Alaska, enabling the first human migrations into the Americas (Nature – see above).
• Multiple waves of migration are now recognized, with some groups traveling along the coast.

Distinct haplogroups in Indigenous populations

• Mitochondrial DNA haplogroups A2, B2, C1c, D1, and X2a are characteristic of Indigenous American populations, rarely found outside the Americas (National Human Genome Research Institute).
• Studies estimate a split from East Asian ancestry around 25,000 years ago, with a period of isolation in Beringia before entering the Americas (Nature).

The pattern: while no single “Native American gene” exists, the DNA evidence points clearly to a Siberian origin with subsequent diversification in the Americas.

Are Native Americans US citizens?

The Indian Citizenship Act of 1924

• On June 2, 1924, President Calvin Coolidge signed the Indian Citizenship Act, granting U.S. citizenship to all Native Americans born in the country (Native American Rights Fund – see card 1).
• Before 1924, some Native Americans could obtain citizenship through marriage, military service, or by accepting land allotments — but it was not universal.

Dual citizenship with tribal nations

• Native Americans are citizens of both the United States and their tribal nation. The Native American Rights Fund explains that tribal citizenship is a political classification, not a racial one.
• This dual-citizen status is unique: tribal governments have inherent sovereignty and can set their own membership rules.

Voting rights and historical barriers

• Even after 1924, some states continued to bar Native Americans from voting — for example, New Mexico and Arizona allowed it only after a 1948 court ruling (ACLU).
• Today, all Native Americans born in the U.S. are citizens by birth and have full voting rights, though logistical barriers like polling place location remain in some areas.

The implication: citizenship does not guarantee equal access to the ballot box.

What does it mean to be Native American?

Cultural identity and community belonging

• Being Native American can involve legal status, cultural practice, and community recognition — often all three at once (Native Philanthropy).
• Language, ceremonies, and relationships with elders are as central as enrollment for many individuals.

Legal vs. social definitions

• The Native American Rights Fund emphasizes that tribal sovereignty means each tribe defines membership — there is no single federal definition for all purposes.
• Socially, a person who is culturally Native may not be enrolled, and an enrolled person may not be culturally active. Both are valid experiences.

Contemporary Native American life

• While popular media often focuses on reservation life, more than 70% of Native Americans now live in urban areas (National Congress of American Indians).
• Identity is often a combination of ancestry, enrollment, and lived experience — and it evolves over a lifetime.

The catch: there is no single checklist. Each person’s identity is shaped by their tribe’s laws, their family history, and their own connection to the community.

Expert perspectives

“Tribal citizenship is not a matter of race; it is a political classification defined by Tribal Nations’ laws.”

Native American Rights Fund (legal advocacy organization)

“American Indian is a term that usually refers to Indigenous peoples of the contiguous United States and often excludes Alaska Natives and Native Hawaiians.”

Native Philanthropy (grantmaking and research organization)

“The term ‘Indian’ originated with Columbus, who believed he had reached the East Indies.”

Smithsonian National Museum of the American Indian

The forward stake is clear: how America defines Native American identity shapes funding, sovereignty, and the daily lives of millions. For tribal nations, the choice is between preserving sovereignty through their own membership rules or facing pressure to align with federal definitions that may not reflect community values. For individuals, the implication is identity is both a legal status and a lived reality — and the gap between the two is where the most important conversations happen.
