title: Archival Version

description: Summary File 3 contains sample data, which is the information
 compiled from the questions asked of a sample of all people and housing
 units in the United States. Population items include basic population
 totals as well as counts for the following characteristics: 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 and counts for 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, and monthly rent and shelter costs. The
 Summary File 3 population tables are identified with a "P" prefix and
 the housing tables are identified with an "H," followed by a sequential
 number. The "P" and "H" tables are shown for the block group and higher
 level geography, while the "PCT" and "HCT" tables are shown for the
 census tract and higher level geography. There are 16 "P" tables, 15
 "PCT" tables, and 20 "HCT" tables that bear an alphabetic suffix on the
 table number, indicating that they are repeated for nine major race and
 Hispanic or Latino groups. There are 484 population tables and 329
housing tables for a total of 813 unique tables.
