What does the U.S. Census Bureau provide on ancestry?

The Census Bureau provides data on ancestry from the following sources:

  • The American Community Survey (ACS) 1-year estimates provide the most current ancestry data available for the U.S., states, and geographic areas of 65,000 or more population.  The ACS 3-year estimates provide data for all geographic areas of 20,000 or more population.
  • Decennial censuses:  2000, 1990, and 1980 ancestry data are avalable, including census briefs and tables for the U.S. and states.  You can also access 2000 ancestry tables for all geographic areas using American FactFinder.  Both 1990 and 1980 can be accessed from the historical decennial census reports.  Data on ancestry was first collected in the 1980 census.
