Definitions:

• Dissimilarity Index: The dissimilarity index measures, on a scale of 0 to 100, the degree to which two groups are evenly spread among census tracts in a given metropolitan area. A high value indicates that the two groups tend to live in different tracts. A value of 60 or above is considered a very high level of residential segregation. It means that 60% of the members of one group would need to move to a different tract in order for the two groups to be equally distributed. Values of 40 or 50 are usually considered a moderate level of segregation, and values of 30 or below are considered to be fairly low.
