Call to action: Proposed 2030 census changes raise concerns for Native representation, voting maps and funding

Quick summary

A proposed rule published by the Census Bureau on Sept. 10 in the Federal Register would create two new regulatory parts governing the decennial census: one addressing who is counted and where, and another restricting certain demographic questions on the census short form.

The Census Bureau also published a Dear Tribal Leaders Letter requesting tribal input and will hold a virtual tribal consultation from 3 to 4:30 p.m. ET Friday, Oct. 2, 2026. 

The consultation is scheduled just 22 days after the proposed rule’s publication. While tribes have until Nov. 2, 2026, to submit written comments, the live consultation will occur on a compressed timeline for tribal governments reviewing a major decennial census rule. By comparison, some federal tribal consultation rules use at least 30 days’ notice as a benchmark, and Executive Order 13175 calls for “meaningful and timely input” from tribal officials on policies with tribal implications.

That timing matters because the federal government has a trust responsibility to federally recognized tribes, including obligations to protect tribal treaty rights, lands, assets and resources, and to carry out federal law with respect to American Indian and Alaska Native tribes and villages. If the proposed changes make Native communities less visible in federal census data, the government may have a weaker factual basis for meeting treaty, statutory and program obligations, making enforcement, planning and funding more difficult.

Meaningful tribal consultation requires enough time for tribal governments to assess potential impacts, consult internally and submit informed comments before federal decisions are made. The general public comment deadline is Oct. 13, 2026, just 11 days after the tribal consultation.

Native people and the history of who counts

Since the first census in 1790, the census system has been based on counting residents rather than citizens alone. The modern constitutional language has been in place since the 14th Amendment was ratified in 1868. Section 2 requires apportionment by “counting the whole number of persons in each State.”

Native people have a long and complicated history with the census. They were originally excluded from the constitutional apportionment count through the phrase “Indians not taxed.” In the first census most Native people were not counted because the federal government understood many tribal nations as separate sovereigns outside the U.S. tax and citizenship framework.

Over time, the federal government’s approach changed. In 1860, “Indian” first appeared as a race or color category for some Native people. In 1890, the Census Bureau attempted to count all Native people, taxed and untaxed, and published extensive tribal reports. Native people were not fully counted on the regular population schedules until 1940, more than 15 years after the Indian Citizenship Act of 1924 made Native people born in the United States U.S. citizens.

Beginning in 1970, race and tribal affiliation became self-reported on mail-in census forms rather than assigned by enumerators. That shift mattered because earlier census race data often depended on how an enumerator classified someone. Self-identification gave Native people more agency in how they were counted.

That history matters because the proposed rule touches both parts of how Native people have been made visible in the census: who is included in the count used for representation, and what demographic information is collected about the people counted. For Native communities, both questions can affect political representation, federal funding and the government’s ability to understand community needs.

What could change in the 2030 census 

(1) Who is counted for apportionment

The proposal would change who is included in the population count used to divide seats in the U.S. House of Representatives among the states. Under current practice, congressional apportionment is based on the total resident population of the 50 states, including citizens and noncitizens. Foreign citizens living in the United States are counted at the U.S. residence where they live and sleep most of the time, while foreign visitors, such as tourists or business travelers, are not counted.

The proposed rule would count U.S. citizens and lawful permanent residents for apportionment, while excluding undocumented immigrants and foreign citizens whose legal status is “less durable and indefinite” than lawful permanent resident status. That could include some lawful noncitizens who are not green card holders, such as certain visa holders, asylum applicants and others without permanent resident status. The proposal would also redefine “usual residence” as the place where a person has lawfully spent the greatest number of days during a new “census enumeration period,” running from Jan. 3 to April 1 of the census year.

A change to the apportionment count could affect the population numbers used to determine each state’s share of seats in Congress and votes in the Electoral College. States with large foreign-born or noncitizen populations could see the greatest effect if excluded populations are no longer reflected in apportionment counts. That matters for Native communities, too: California and Texas, two states with large foreign-born populations, also have among the nation’s largest American Indian and Alaska Native populations, according to 2020 census data. In 2020, the Trump White House attempted to exclude unauthorized immigrants from the apportionment count through a memorandum that was challenged and blocked by a federal district court in New York, then ultimately dismissed by the Supreme Court, which expressed no view on the merits. While it never took effect, a 2020 Pew Research Center analysis found that excluding unauthorized immigrants could have cost California, Texas and Florida one House seat each. The new proposal could be broader because it may also exclude some lawful noncitizens who are not lawful permanent residents.

Census data also guides redistricting at multiple levels of government. After each decennial census, states and local governments use updated population counts to redraw congressional, state legislative, county, city and school board districts so representation reflects population changes. Those maps can determine whether Native communities are kept together or diluted in political representation. Accurate census data helps ensure that communities, including Tribal Nations and Native people living on and off tribal lands, are fairly represented in political decision-making.

Census data also helps distribute federal funding for public services. More than 300 programs use census-derived figures to assess community needs and allocate resources. For Tribal Nations, accurate population counts, household characteristics, income data, housing conditions and tribal geography can affect funding for housing, health care, roads, education, child care, elder services, community development and disaster planning. That includes programs such as Indian Housing Block Grants, Indian Community Development Block Grants, Tribal Transit, Native American employment and training, public health programs in Indian Country and Urban Indian Health Services.

(2) Demographic data

The second major piece of the proposal would prohibit questions about race, ethnicity or sexual orientation on the decennial census short-form questionnaire or any questionnaire used for enumeration. The Census Bureau says the goal is to reduce response burden, protect privacy, avoid disclosure risks and keep the census focused on apportionment. The proposal would not restrict demographic questions on the American Community Survey or other surveys that are not used for enumeration. It also would not prevent the Bureau from receiving demographic data from other sources.

The proposal recognizes that tribal membership is not the same as race or ethnicity, because federally recognized tribes hold a distinct political and legal status. Federal law has long treated classifications based on Indian race or ethnicity differently from those based on affiliation, membership or citizenship in a federally recognized tribe. In Morton v. Mancari, which the proposal cites, the Supreme Court explained that certain preferences for members of federally recognized tribes are tied to that unique legal status, rather than to race alone. This distinction may leave room for some collection of tribal-affiliation data even if questions about race and ethnicity are limited.

But the proposal also highlights the Bureau’s growing reliance on administrative records, including state, local, tribal and federal agency records, as well as commercial data. That raises an important concern: whether Native population visibility would come to depend more heavily on the ACS, administrative data or tribal records, and whether those sources would capture Native identity, tribal affiliation and community needs as accurately and consistently as direct census responses.

Tribal-serving organizations, including the National Congress of American Indians and Native American Rights Foundation, have raised concerns that removing race and ethnicity questions from the short form could reduce the visibility of American Indian and Alaska Native populations and affect data used for housing, community development, maternal health, transportation and other services in Indian Country and Alaska Native communities.

Race and ethnicity data can also help show whether Native communities are being underserved or discriminated against in voting, education, health, policing and other policy areas. Because Native populations have historically been excluded, misclassified and undercounted, removing or limiting demographic data raises concerns about repeating that invisibility in a modern form.

Taken together, the proposed changes raise questions about both representation and visibility: who is counted for apportionment, and what information is collected about Native people and communities. Because those decisions can shape voting maps, federal funding and the data used to meet trust and program obligations, meaningful tribal consultation is essential before any final rule is adopted.
