Each decade, the Population Estimates Program has the opportunity to make comparisons between the final series of estimates for the decade and the latest decennial census to assess the accuracy of the estimates. Differences between the estimates and Census counts are typically interpreted as error in the estimates and are used to inform research and methodological improvements over the decade.

Vintage 2010 Population Estimates and 2010 Census Counts for the United States, States, Counties, Puerto Rico, and Subcounty Areas

The Vintage 2010 estimates were compared against the 2010 Census to evaluate the accuracy of the estimates. They are based on Census 2000 and were created without incorporation or consideration of the 2010 Census results. For background on how the estimates were produced, see the Release Notes for Vintage 2010 Estimates. For full methodological detail on the production of population estimates, please refer to Vintage 2009 methodology statements.

United States Demographic Characteristics - Released March 2012

Note: The file "NC-EST2010-ALLDATA.csv" that was previously available was incorrectly aggregated. The sum of the five race groups (each OMB race alone or in combination with other races) equaled the total population, even though people of more than one race should have been represented multiple times. The file was replaced with a corrected version on September 10, 2012.

Alternative Vintage 2010 Total Population Estimates and 2010 Census Counts for the United States, States, Counties, and Subcounty Areas

The U.S., state, and county estimates described above were produced with the Administrative Records Method, which incorporate special censuses and local challenges. The following estimates were produced with the same method, but without incorporating special censuses and local challenges. The subcounty estimates described above were produced using the methodology in place as of 2009. The following subcounty estimates were produced with the same method, but without incorporating official adjustments made during processing. These adjustments account for special censuses, local challenges, and other data accepted as part of our formal review process.
