New Racial Segregation Measures for Large Metropolitan Areas: Analysis of the 1990-2010 Decennial Censuses


Segregation Indices are Dissimilarity Indices that measure the degree to which the minority group is distributed differently than whites aross census tracts. They range from 0 (complete integration) to 100 (complete segregation) where the value indicates the percentage of the minority group that needs to move to be distributed exactly like whites.

The neighborhood compositions for average members of a racial group is based on the calculation of exposure indices (each tracts racial composition is weighted by the group's size of each tract) For further information on calculation of these indices see Frey and Myers, 2005.

Note: In this analysis all racial groups (whites, blacks, asians and other races) are non-Hispanic members of those races. Hispanics are shown as a separate category.
