Inter-university Consortium for Political and Social Research 1989 1989-03-03 2006-01-18 aggregate data 8870 1 This data collection was designed to test a priori theory on macrostructures and intergroup relations by examining theoretical predictions related to SMSA social structure and conditions, intermarriage, and crime in the United States. The collection utilizes a broad range of 1970 census data aggregated at the SMSA level. Part 1 presents intermarriage rates that take into account factors such as occupation, education, income, language, and age. Also included are structural and control measures calculated from the 1960 census. Part 2 provides 1970 structural variables including detailed information on marital status, occupation, ethnicity, language, education, age, race, income, and derived heterogeneity and inequality indices.
