Description

In 1990, tribal information is included for all persons who reported their race as American Indian or Alaska Native. In the 2000 census, 2010 census, the ACS, and the PRCS tribal information is only available for American Indians and Alaska Natives who reported a single race. Multi-racial American Indians and Alaska Natives may have written tribal information on the census form, but their tribal information is not available in the public use samples for confidentiality reasons.

In 1900 and 1910, tribal information is available only for Alaskan residents and for American Indians who were enumerated on the American Indian schedules. The modified schedule used to enumerate American Indians in 1900 and 1910 contained a field labeled "Tribe of this Indian." Enumerators were instructed to "secure the name of the tribe with which the person is connected." The schedule used to enumerate Alaskan residents in 1900 and 1910 also contained a field for "Tribe or Clan."

MTRIBE and FTRIBE provide the same information about respondents' parents in 1900 and 1910.

Comparability

In 2023, the Census Bureau implemented changes to the race question due to improvements made to the race question in 2020. New codes were added for Alaska Native alone, Aztec, Inca, Maya, Mixtec, Taino, Tarasco, All other Latin American Indian, Oglala Sioux, Rosebud Sioux, and Cheyenne River Sioux tribes. The addition of these detailed codes impacts the comparability of general codes between 2023-onward and 2022-prior years. Note about 2023 multiyear samples: People in the multiyear sample who were surveyed in 2023 were assigned the new 2023 codes, whereas people surveyed in years prior to 2023 (2019-2022) were assigned pre-2023 codes.

Users interested in comparing TRIBE over time should know that there may be different codes for the same field across samples. Furthermore, as the Census continues to develop its classification system for this variable, codes may be renamed, added, deleted, or compressed. IPUMS preserves each sample's full range of codes.
