American Community Survey (ACS): Public Use Microdata Sample (PUMS), 2005

The American Community Survey (ACS) is a part of the
Decennial Census Program, and is designed to produce critical
information about the characteristics of local communities. The ACS
publishes social, housing, and economic characteristics for
demographic groups covering a broad spectrum of geographic areas in
the United States and Puerto Rico. Every year the ACS supports the
release of single-year estimates for geographic areas with populations
of 65,000 or more. Demographic variables include sex, age,
relationship, households by type, race, and Hispanic origin. Social
characteristics variables include school enrollment, educational
attainment, marital status, fertility, grandparents caring for
children, veteran status, disability status, residence one year ago,
place of birth, U.S. citizenship status, year of entry, world region
of birth of foreign born, language spoken at home, and ancestry.
Variables focusing on economic characteristics include employment
status, commuting to work, occupation, industry, class of worker,
income and benefits, and poverty status. Variables focusing on housing
characteristics include occupancy, units in structure, year structure
built, number of rooms, number of bedrooms, housing tenure, year
householder moved into unit, vehicles available, house heating fuel,
utility costs, occupants per room, housing value, and mortgage status.
The American Community Survey is conducted under the authority of
Title 13, United States Code, Sections 141 and 193, and response is
