Download US Population Data - 1969-2011

Note: The 1969-2012 US Populations are now available. The 1969-2011 data files will continue to be available through for download May 15, 2014.

Files containing US population data are provided for analysis using your own statistical software or using SEER*Stat (you must use the SEER*Prep software to create a database for use in SEER*Stat).


  • The U.S. Census Bureau annually releases unbridged population estimates for five-year age groups and race at the county levelExternal Web Site Policy. The Census Bureau does not release bridged race estimates by single year of age at the county level due to concerns about the reliability of these estimates. However, these estimates are provided to the National Cancer Institute to meet programmatic needs such as the creation of age groupings that differ from the standard groupings used by the Census Bureau. Users of the single-year-of-age county-level bridged race population estimates should carefully consider the limited reliability of these estimates.
  • All of the populations change annually going back to the last decennial census (see Population Estimates Used in NCI's SEER*Stat Software).

Available Files

Populations are available for the following time periods and "races":

  • 1969-2011 County-level: White, Black, Other;
  • 1990-2011 County-level: Expanded Races (White, Black, American Indian/Alaska Native, Asian/Pacific Islander) by Origin (Hispanic, Non-Hispanic);
  • 1981-2011 State-level: Expanded Races (White, Black, American Indian/Alaska Native, Asian/Pacific Islander). See State-Level Race and Hispanic Origin Population Estimates for the methodology.
  • 1981-2011 State-level: White and Non-White by Hispanic Origin

County- and state-level population files with 19 age groups (<1, 1-4, ..., 80-84, 85+) and with 86 single-year age groups (<1, 1, 2, ..., 84, 85+) are provided below.

For the All States Combined and four states (Alabama, Louisiana, Mississippi, and Texas), two sets of population estimates are available for 2005: the standard set based on July 1 populations and a set that has been adjusted for the population shifts due to hurricanes Katrina (August 29) and Rita (September 24). For more information, see Adjusted Populations for the Counties/Parishes Affected by Hurricanes Katrina and Rita.
