Dynamic collection composed of a wide selection of analytical measures, encompassing a variety of domains, all derived from a number of disparate data sources. There are currently 7 studies derived for a variety of substantive areas including: Cost-of-Living, Disability, Pollution, Segregation Indices, Street Connectivity, an Index of Neighborhood Socioeconomic Status, and an Abridged Decennial Census. The 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 number and comprehensiveness of the measures derived within each data set vary according to the expansiveness of the substantive area. Generally speaking, the time periods for which these data are available is the 1990-2000 time period, though data are available for years before and after this time frame, depending upon the data set.
