Summary File 1 (SF 1)

Summary File 1 (SF 1) contains 286 detailed tables focusing on age, sex, households, families, and housing

units. These tables provide in-depth figures by race and Hispanic origin; some tables are repeated for each of

nine race/Latino groups. Counts also are provided for over forty American Indian and Alaska Native tribes

and for groups within race categories. The race categories include eighteen Asian groups and twelve Native

Hawaiian and Other Pacific Islander groups. Counts of persons of Hispanic origin by country of origin

(twenty-eight groups) are also shown.

Summary File 1 presents data for the United States, the 50 states, and the District of Columbia in a

hierarchical sequence down to the block level for many tabulations, but only to the census tract level for

others. Summaries are included for other geographic areas such as ZIP Code Tabulation Areas (ZCTAs) and

Congressional districts.

sequence down the block level for many tabulations, but only to the census tract level for others. Geographic
