US Census Summary File 1 (2010)

These Summary File 1 tables provide the most detailed counts available so far from the 2010 Census, including cross-tabulations of age, sex, households, families, relationship to householder, housing units, detailed race and Hispanic or Latino origin groups, and group quarters at the census tract level.

Census Bureau Releases New Local-Level Demographic Information from 2010 Census for California.

What’s Unique in Summary File 1 ?

Summary File 1 provides new layers of detail about the topics covered in the 2010 Census and cross-tabulates many of these topics to provide a more nuanced picture. Beyond just providing counts of families, for example, the summary file also shows the number of families by type, by the age of the children present and by race and Hispanic origin of the householder.

Many of the tables are repeated for nine race and Hispanic or Latino origin groups: 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, two or more races, Hispanic or Latino, and white alone not Hispanic or Latino.

New topics include:

  • Single year of age by sex
  • More detail on children, including adopted, stepchildren and grandchildren
  • Race and Hispanic origin of householder
  • More detail on household relationships
  • Group quarters population by sex, age and group quarters type
  • Housing tenure (rented or owned) by age, household type, race and Hispanic origin of householder
  • Mortgage status of owned housing units

Counts about previously unreleased race and Hispanic or Latino origin groups are also available, including:

  • American Indian and Alaska Native tribal groupings, such as Cheyenne, Navajo and Yup’ik
  • Asian groups, such as Bangladeshi, Hmong and Pakistani
  • Hispanic origin groups, such as Argentinean, Colombian and Guatemalan
  • Native Hawaiian and Other Pacific Islander groups, such as Fijian, Marshallese and Tongan

Geographies Available

With today’s release, tables are available for states, counties, county subdivisions, places, census tracts, ZIP code tabulation areas, congressional districts for the 111th Congress and, where applicable, American Indian and Alaska Native areas and Hawaiian home lands. For most subjects, statistics for census block groups and blocks are also shown.
