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.
