The American Indian and Alaska Native Summary File (AIANSF) presents information on the population and housing data collected on a sample basis from the Census 2000 long form questionnaire (PDF - 627 KB), as well as the topics from the short form (PDF - 424 KB) 100-percent data (age, race, sex, Hispanic or Latino origin, tenure [whether a housing unit is owner- or renter-occupied], and vacancy status).
Each AIANSF detailed table is repeated or iterated for the total population, the total American Indian and Alaska Native population, the total American Indian population, the total Alaska Native population, and for 1,081 additional specified American Indian and Alaska Native tribes.
Please note that tables are repeated only if a specific population threshold is met. The population for the particular iteration in a specific geographic area must be at least 100 people (based on a 100-percent count) of the specified population and include at least 50 unweighted sample cases. This threshold is based on respondents who reported only one tribe.
