Segregation Results from 2010

Segregation Results from Census 2010

Following the release of redistricting data from the 2010 Census, we at SSDAN calculated scores for several different measures of residential racial segregation and posted some of these on a website at the University of Michigan's Population Studies Center.  The interest in these measures was substantial and resulted in considerable attention to one article in particular.  Dan Denvir of wrote a piece titled "The 10 Most Segregated Urban Areas in America," which aimed to give some historical context behind the metropolitan areas with the highest dissimilarity scores.  The article included a slideshow with maps SSDAN created showing the racial composition of individual neighborhoods within each of the 10 most segregated metro areas. 

Below, you can find the maps we created for the article as well as additional segregation scores we hadn't previously released.

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.

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