Profile of Selected Social CharacteristicsTable DP-3. Profile of Selected Economic CharacteristicsTable DP-4. Profile of Selected Housing CharacteristicsThe 100-percent data were obtained from the questions asked of every person and housing unit enumerated in Census 2000, while the sample data were taken from the questions asked of a sample of persons and housing units. Tabulated from the 100- percent data, Table DP-1 shows population counts by sex, age, race, Hispanic origin, and relationship to householder, plus the group-quarters population, households by type, housing occupancy and tenure, and average household size. Tables P-2, DP-3, and DP-4 were derived from the sample data. Table DP-2 covers school enrollment, educational attainment, marital status, grandparents as caregivers, veteran status, disability status, residence in 1995, nativity and place of birth, language spoken at home, and ancestry. Next, Table DP-3 covers employment status, commuting to work, occupation, industry, class of worker, and income and poverty status in 1999. The last table, DP-4, shows the number of housing units by type of structure and number of rooms in unit, year structure was built, year householder moved into unit, number of vehicles available, type of house heating fuel, occupants per room, value of owner-occupied units, gross rent, and mortgage status and selected monthly owner costs, as well as the number of homes without complete plumbing facilities, complete kitchen facilities, or telephone service.Supplied in a national file and separate state files including the District of Columbia and Puerto Rico, the data cover more than a dozen geographic levels of observation known as "summary levels" in the Census Bureau's nomenclature. The national file comprises eight summary levels: United States, regions, divisions, Metropolitan Statistical Areas/Consolidated Metropolitan Statistical Areas, Primary Metropolitan Statistical Areas, American Indian Areas/Alaska Native Areas/Hawaiian Home Lands, states, and the 106th Congressional Districts. Ten summary levels are reported in the state files: state, counties, county subdivisions, places, consolidated cities, Metropolitan Statistical Areas/Consolidated Metropolitan Statistical Areas, Primary Metropolitan Statistical Areas, American Indian Areas/Alaska Native Areas/Hawaiian Home Lands, Alaska Native Regional Corporations, and the 106th Congressional Districts.The data are provided in 53 ZIP archives: one for each state and one with the national file. Each of these archives comprises four comma-delimited ASCII data files (one per table) and a ZIP archive with the tables in PDF format. The embedded ZIP archive contains a separate PDF file for each iteration of every summary level, an HTML file with an index and links to the PDF files, and a folder with Graphic Interchange Format (GIF) image files which are used by the HTML document.
