title: Census of Population and Housing, 2000 [United States]: Summary File 4, National
title: Version 2

description: Summary File 4 (SF 4) from the United States 2000 Census
contains the sample data, which is the information compiled from the
questions asked of a sample of all people and housing units. Population
items include basic population totals: urban and rural, households and
families, marital status, grandparents as caregivers, language and
ability to speak English, ancestry, place of birth, citizenship status,
year of entry, migration, place of work, journey to work (commuting),
school enrollment and educational attainment, veteran status,
disability, employment status, industry, occupation, class of worker,
income, and poverty status. Housing items include basic housing totals:
urban and rural, number of rooms, number of bedrooms, year moved into
unit, household size and occupants per room, units in structure, year
structure built, heating fuel, telephone service, plumbing and kitchen
facilities, vehicles available, value of home, monthly rent, and shelter
costs. In Summary File 4, the sample data are presented in 213
population tables (matrices) and 110 housing tables, identified with
"PCT" and "HCT" respectively. Each table is iterated for 336 population
groups: the total population, 132 race groups, 78 American Indian and
Alaska Native tribe categories (reflecting 39 individual tribes), 39
Hispanic or Latino groups, and 86 ancestry groups. The presentation of
SF4 tables for any of the 336 population groups is subject to a
population threshold. That is, if there are fewer than 100 people
(100-percent count) in a specific population group in a specific
geographic area, and there are fewer than 50 unweighted cases, their
population and housing characteristics data are not available for that
geographic area in SF4. For the ancestry iterations, only the 50
unweighted cases test can be performed. See Appendix H: Characteristic
Iterations, for a complete list of characteristic iterations.

description: Because of the number of files per state in Summary
File 4, ICPSR has given each state its own ICPSR study number in the
range ICPSR 13512-13563. The study number for the national file is
13570. Data for each state are being released as they become available.The data are provided in 38 segments (files) per iteration. These
segments are PCT1-PCT4, PCT5-PCT16, PCT17-PCT34, PCT35-PCT37,
PCT38-PCT45, PCT46-PCT49, PCT50-PCT61, PCT62-PCT67, PCT68-PCT71,

The iterations are Parts 1-336, the Geographic Header File is Part 337.
The Geographic Header File is in fixed-format ASCII and the table files
are in comma-delimited ASCII format. A merged iteration will have 7,963
variables.For Parts 251-336, the part names contain numbers within
parentheses that refer to the Ancestry Code List (page G1 of the
codebook).
