FRED Adds County Racial Dissimilarity Data

These 3,143 county-level series measure the percentage of a racial group’s population in a county who would have to move Census tracts for each tract in that county to have the same percentage of that group as the whole county. Jahn, Schmid and Schra originally developed this process of measuring racial equalization in 1947. The U.S. Census Bureau’s American Community Survey provides the composite county- and tract-level data.
