RAND Center for Population Health and Health Disparities (CPHHD) Data Core Series: Segregation Indices, 1990-2000 [United States]

The RAND Center for Population Health and Health Disparities (CPHHD) Data Core Series is composed of a wide selection of analytical measures, encompassing a variety of domains, all derived from a number of disparate data sources. The CPHHD Data Core's central focus is on geographic measures for census tracts, counties, and Metropolitan Statistical Areas (MSAs) from two distinct geo-reference points, 1990 and 2000. The current study, Segregation Indices, has cross-sectional and longitudinal data sets, containing a number of non-spatially sensitive segregation indices based on the main Decennial Census. These indices are considered non-spatial in that the indices did not take into account any spatial relationships of the geographical entities (i.e., distances apart, clustering within, spatial concentrations, etc.), only association of tracts with either County and/or MSA. In addition, the data are summarized at two different geographic levels: County (Geographic) and MSA (Geographic). The data consist of 11 different segregation indices, with several different binary indicators, and a 5-race indicator. Measures include: Normalized Simpson Interaction Diversity Index, Entropy Diversity Index, Dissimilarity Segregation Index, Gini Segregation Index, Information Theory Segregation Index, Squared Coefficient of Variation Segregation Index, Relative Diversity Segregation Index, N-group Normalized Exposure Segregation Index, Exposure Index, Isolation Index, and 2-group Normalized Exposure Index.
