DEMOGRAPHIC THEME GROUP

This theme group contained data sets describing the human population of the Basin, by geographical units such as counties, towns (named places), U.S. Census Bureau defined blockgroups, tracts or places. Data consisted of demographic statistics from the 1990 U.S. census, and other social, economic and lifestyle data. Census geographies and 1990 U.S. census information were extracted from Wessex Corp. "Profiler" and "Tiger 92" datasets. The census data provided information regarding: population, gender balance, age, racial composition, employment, income, poverty level, education level, etc. Lifestyle information was contained in the PRIZM dataset purchased from Claritas Corp. This dataset provided proportions of households within each census tract belonging to each of 62 lifestyle clusters. The clusters are determined by cluster analysis of standard Census demographic information plus a wealth of consumer behavior data. These demographic datasets were valuable to the social scientists for describing the human population of the Basin.
