E-5 Population and Housing Estimates for Cities, Counties, and the State, 2011-2020 with 2010 Census Benchmark

May 2021


This report provides the revised population and housing estimates for January 1, 2011-2020 for the state, counties, and cities. These population estimates incorporate 2010 census counts.

Note: Data in this report have not been adjusted for differences between the Demographic Research Unit’s estimates on April 1, 2020 and census counts of the same day. Further information is needed from the 2020 Census Detailed Demographic and Housing Characteristic file to be released in mid-2023.


For Methodology and Data Considerations, see the report E-4 Population Estimates for Cities, Counties, and the State, 2011-2020 with 2010 Census Benchmark.

Data Considerations

Sources. Data used in estimation models come from administrative records of several state and federal government departments and agencies, and from the local jurisdictions for which Finance produces population estimates. Because timeliness and coverage in these series vary, corrections, smoothing, and other adjustments may be applied. Changes to 2010 Summary File 1 data in the classification of student housing on or near campus was necessary to remain consistent with the census group quarters definition. In only a few instances, some student housing (residence hall and apartment units) counted as household population in the census was redefined as group quarters student housing population. College dorm group quarters population is defined as student population living in residence halls and apartment units located on or near college campuses.
