The 2020 Demographic Analysis (DA) tables feature national estimates of population and net coverage error. The estimates of population are available by age, sex, race, and Hispanic origin developed from administrative records, to be used to assess coverage in the decennial census.

Net coverage error is calculated as the percent difference between the census count and the DA estimate:

Net Coverage Error = 100 x [(Census Count - DA Estimate)/DA Estimate]

Please refer to the methodology statement for more detail on how the DA population estimates were produced.
