Note: Selected Metropolitan Areas are those with at least 10 tracts and 3 percent or 20,000 or more of the racial/ethnic group in 1980. Higher values indicate more segregation; the reference group is White non-Hispanic. Segregation estimates are weighted by the size of the applicable minority group population.
