Single-Race Resident Population Estimates
United States, State and County
for the years 2010 - 2020

Single-Race Population Estimates Data Summary

Summary:   

The Census Bureau releases single-race population estimates of the July 1st resident population of the United States. These estimates are based on the April 1st 2010 Census counts, with six "single-race" race categories as specified in the 1997 Office of Management and Budget (OMB) standards for the collection of data on race and ethnicity: American Indian or Alaska Native, Asian, Black or African American, Native Hawaiian or Pacific Islander, White, More than one race. Beginning in 2016, all jurisdictions and the National Center for Health Statistics are reporting race consistent with the 1997 Office of Management and Budget standards ("single race"). Single race is defined as one race reported on the birth certificate.

About different "vintages" or series of population estimates:

  • The "Vintage 2020" series of postcensal estimates are July 1 resident population estimates for years 2010 - 2020. July 1, 2020 population estimates are the denominators for 2020 birth and death rates reported by the National Center for Health Statistics.
  • The "Vintage 2019" series of postcensal estimates are July 1 resident population estimates for years 2010 - 2019. July 1, 2019 population estimates are the denominators for 2019 birth and death rates reported by the National Center for Health Statistics.
  • The "Vintage 2018" series of postcensal estimates are July 1 resident population estimates for years 2010 - 2018. July 1, 2018 population estimates are the denominators for 2018 birth and death rates reported by the National Center for Health Statistics.
  • The "Vintage 2017" series of postcensal estimates are July 1 resident population estimates for years 2010 - 2017. July 1, 2017 population estimates are the denominators for 2017 birth and death rates reported by the National Center for Health Statistics.
  • The "Vintage 2016" series of postcensal estimates are July 1 resident population estimates for years 2010 - 2016. July 1, 2016 population estimates are the denominators for 2016 birth and death rates reported by the National Center for Health Statistics.

About postcensal and intercensal population estimates:

  • Postcensal estimates:
    Postcensal population estimates are estimates made for the years following a census, before the next census has been taken. Postcensal estimates are derived by updating the resident population enumerated in the decennial census using various measures of population change. Each year following the decennial census, the U.S. Census Bureau produces a series of postcensal estimates that includes estimates for the current data year and revised estimates for earlier years. Estimates for earlier years in a given series are revised to reflect 1) changes in the components of population change data sets (for example, a preliminary natality file is replaced with a final natality file), 2) challenges to the population estimates, and 3) changes in the estimation methodology. A series of estimates is referred to as a Vintage and the last year in a series is used to name it. For example, the Vintage 2019 postcensal series has estimates for July 1, 2010, July 1, 2011, July 1, 2012, July 1, 2013, July 1, 2014, July 1,2015 July 1, 2016, July 1, 2017, July 1, 2018, July 1, 2019, and July 1, 2020. Because of the revisions made to the estimates in each series, estimates for a given year from different series will differ.
  • Intercensal estimates:
    Intercensal population estimates are estimates made for the years between two completed censuses which take into account both censuses. Intercensal estimates are derived by adjusting the final postcensal series of estimates for the decade to account for differences between the enumerated April 1, census counts (from the census at the end of the decade) and the postcensal estimates of the April 1 population (from the final postcensal series). For example, after completion of the 2020 census, the postcensal estimates for the period between April 1, 2010 and April 1, 2020 were modified to account for differences between the April 1, 2020 census count and April 1 postcensal estimate (based on the 2010 census). The patterns of population change observed over the decade are preserved. Intercensal estimates supersede the postcensal estimates previously made for the time period. The 2010-2019 intercensal estimates are based on both the 2010 and 2020 census counts.

  2. You cannot make charts when your data has more than two By-Variables.
  3. You cannot make charts for data grouped by State and also by County.
  4. When grouping by more than one geographic variable, select them in order of size. For example, group by region, and by state, and by county.


Step 2. Select location:

Limit your data request to specific locations here. The default settings are national data, the United States.


Location

Use this field to specify the location or locations to be included in the data request. You may select a single county or a group of counties, a single state or a group of states, one or more regions, or the total U.S. Be sure the button for the geographic list you want to use is checked when selecting location values.

Step 4. Other options:
Export Results:    If checked, then query results are exported to a local file. More information on how to import this file into other applications can be found here.
How?   See Check Box.
Show Totals:    If checked, then totals and sub-totals display in the results table.
How?   See Check Box.
Show Zero Values:    If checked, then rows containing zero counts display in the results table. If unchecked, then zero count rows are not displayed.
How?   See Check Box.
Precision:    Precision is not available for this dataset because population counts are whole numbers.
Data Access Timeout:    This value specifies the maximum time to wait for the data access for a query to complete.

Notes:   
  • The potential for error is greatest for the smallest population groups, particularly the smaller race groups and county level estimates. Although efforts are made to use the best available data and methods to produce estimates, the modeling process introduces error into the estimates.
  • Postcensal population estimates are estimates made for the years following a census, before the next census has been taken. Postcensal estimates are derived by updating the population enumerated in the decennial census using various measures of population change.
  • Intercensal population estimates are made for the period of time between decennial census years after the second census is completed, and such estimates replace the previous population projections for the time period. For example, the 1990-1999 intercensal estimates, which represent a revision of the annual time series of July 1 county postcensal population estimates by age, sex, race and Hispanic origin, were produced by the Population Estimates Program of the U.S. Bureau of the Census. These intercensal population estimates are based on the estimates of the April 1, 2000 resident population developed by the Bureau of the Census.
  • County Geography
    Location changes at the county level include:
    • Bedford City, Virginia (FIPS code 51515), formerly an independent city, merged with Bedford County (FIPS code 51019) on July 1, 2013.
    • Shannon County, South Dakota (FIPS code 46113) was renamed to Oglala Lakota County, South Dakota (FIPS code 46102) effective July 1, 2015.
    • Wade Hampton Census Area, Alaska (FIPS code 02270) was renamed to Kusilvak Census Area, Alaska (FIPS code 02158) effective July 1, 2015.
