American Indian and Alaska Native Summary File (AIANSF)


The American Indian and Alaska Native Summary File (AIANSF) contains sample data, which is the information compiled from the questions asked of a sample of all people and housing units.

The sample data are presented in 213 population tables (matrices) and 110 housing tables, identified with "PCT" and "HCT," respectively. The tables are 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. For any of these iterations, tables will be shown only if the specific population threshold is met. The population for the specific 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.

The AIANSF is released as one file providing data for the United States, regions, divisions, states (excluding Puerto Rico as a state equivalent), metropolitan areas, American Indian and Alaska Native areas, and Hawaiian home lands.
