title: Census of Population and Housing, 2000 [United States]: Demographic Profile: 100-percent and Sample Data
title: Version 1

description: This data collection contains four tables derived from the
Census 2000 100-percent and sample data:

Table DP-1. Profile of General Demographic Characteristics
Table DP-2. Profile of Selected Social Characteristics
Table DP-3. Profile of Selected Economic Characteristics
Table DP-4. Profile of Selected Housing Characteristics
The 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.
description: Every person and housing unit in the United States was
 asked basic demographic and housing questions (for example, sex, age,
 race, and relationship to householder). A sample of the persons and
 housing units was asked more detailed questions. The sampling unit for
 Census 2000 was the housing unit, including all occupants. There were
 four different housing unit sampling rates, 1-in-8, 1-in-6, 1-in-4,
and 1-in-2, designed to yield an overall average of about 1-in-6.
