Note: Selected Metropolitan Areas (13 of 330) are those with at least 10 tracts and 3% or 20,000 or more American Indians and Alaska Natives in 1980. Higher values indicate more segregation; the reference group is non-Hispanic Whites. Segregation estimates are weighted by size of the American Indian/Alaska Native population
