Access Summary File 2 tables and maps visit American FactFinder.

Summary File 2 (SF 2) contains 100% data from the 2000 Census, meaning that, the information is compiled from questions asked of all people and about every housing unit. This file contains 47 detailed tables focusing on age, sex, households, families, and occupied housing units for the total population. These tables are repeated for 249 detailed population groups based on the following criteria:

• no tables are available for geographic areas having a population of less than 100
• tables are repeated only for the race group, American Indian and Alaska Native tribes, and Hispanic or Latino groups having a population of 100 or more within the geographic area.

For a complete list of the 249 population groups, see Appendix H of the SF 2 Technical Documentation (PDF).
