Census of Population and Housing, 2000 [United States]: Selected Subsets From Summary File 1, States United States Department of Commerce. Bureau of the Census Inter-university Consortium for Political and Social Research census data demographic characteristics employment ethnicity families household composition housing housing conditions occupations population ICPSR.I.A.1.e Prepared by the Inter-university Consortium for Political and Social Research, this data collection consists of selected subsets extracted from the CENSUS OF POPULATION AND HOUSING, 2000 [UNITED STATES]: SUMMARY FILE 1, STATES (ICPSR 3194). Summary File 1 data contain information compiled from the questions asked of all people and of every housing unit enumerated in Census 2000: sex, age, race, Hispanic or Latino origin, type of living quarters (household/group quarters), household relationship, housing unit vacancy status, and housing unit tenure (owner/renter). The information is presented in 286 tables, one variable per table cell, plus additional variables with geographic information. Cases in the summary file data are classified by levels of observation, known as "summary levels" in the Census Bureau's nomenclature, which served as the selection criteria for the subsets. Each subset comprises all of the cases in one of two summary levels: whole census tracts (summary level 140) and census tracts in places (summary level 158). The latter covers whole tracts completely within places and portions of tracts that cross place boundaries. Five files are provided for each subset. There is a file for each of the four census regions (East, Midwest, South, and West) and a combined national file. Puerto Rico is included in the national and South files. 2006-01-18 census data 13395 10.3886/ICPSR13395.v1 self-enumerated questionnaires United States 2000 ICPSR metadata records are licensed under a Creative Commons Attribution-Noncommercial 3.0 United States License (http://creativecommons.org/licenses/by-nc/3.0/us/).
