The release of Vintage 2010 estimates provides the opportunity to make comparisons with the 2010 Census and previously released estimates. The following sets of evaluation estimates are now available. 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 for National, State and County, Puerto Rico population estimates, State and County Population Estimates by Age, Sex, Race, and Hispanic Origin, and Incorporated Place and Minor Civil Division Population Estimates.
Additional annual Vintage 2010 estimates have been prepared for the components of population change (births, deaths, and migration), as well as for demographic characteristics of the population (age, sex, race, and Hispanic origin).
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.
This set of national, state, county, and subcounty population estimates were prepared as an evaluation set of 1990 based population estimates. These estimates were prepared using the methodology in place in the late 1990s, with the April 1, 1990 Census as the base, and the latest input data available in early 2000. The results of these 1990 based estimates for 2000 compared to the Census 2000 enumerated population provide the basis for evaluating the population estimates prepared by the Population Estimates and Projections Program during the 1990s.
