Summary File 3 (SF 3) 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, and year of entry; migration; place of work; journey to work (commuting); school enrollment and educational attainment; veteran status; disability; employment status; industry, occupation, and 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 3, population tables are identified with a "P" and housing tables are identified with an "H" prefix, followed by a sequential number. The "P" and "H" tables are shown for the block group and higher levels of geography, while the "PCT" and "HCT" tables are shown for the census tract and higher levels of 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.1
Summary File 3 contains a total of 813 unique tables-484 population tables and 329 housing tables. The chart below summarizes the geographic coverage available for the tables and the tables that are repeated by race and Hispanic or Latino.
1These selected tables are repeated by the following: White alone; Black or African American alone; American Indian and Alaska Native alone; Asian alone; Native Hawaiian and Other Pacific Islander alone; Some other race alone; Two or more races; Hispanic or Latino; and White alone, not Hispanic or Latino.
SF 3 includes population and housing characteristics for the total population and for a limited list of race and Hispanic or Latino groups. Population and housing items may be cross tabulated. Selected aggregates and medians also are provided. A complete listing of subjects in this file is found in the section, "Subject Locator."

Summary File 3 (SF 3) is released as individual files for each of the 50 states, the District of Columbia, Puerto Rico, and the United States. The tables (matrices) are identical for all files, but the geographic coverage differs.
This abstract lists the most frequently accessed geographic levels. The "Summary Level Sequence Chart" section outlines the hierarchical and inventory geographic summaries in their entirety. Two summary level sequence charts are provided: one for the state files and one for the final national file.
