The dissimilarity index measures the relative separation or integration of groups across all neighborhoods of a city or metropolitan area. If a city's white-black dissimilarity index were 65, that would mean that 65% of white people would need to move to another neighborhood to make whites and blacks evenly distributed across all neighborhoods.

* When a group's population is small, its dissimilarity index may be high even if the group's members are evenly distributed throughout the area. Thus, when a group's population is less than 1,000, exercise caution in interpreting its dissimilarity indices.
