BEA state per capita personal consumption expenditures statistics are calculated by dividing population into personal consumption expenditures. BEA used Census population figures to calculate annual per capita personal consumption expenditures statistics for 2020 and 2021. For 2010 through 2019, BEA produced intercensal annual state population statistics that are tied to the Census Bureau decennial counts for 2010 and 2020. BEA developed intercensal population statistics because this data was not published when Census released state population data for 2020 and 2021, which are based on the 2020 decennial counts. Census will release official intercensal population data in 2023.

BEA produced intercensal population figures to create consistent time series that are used to prepare per capita personal consumption expenditures statistics. BEA used the Census Bureau Das Gupta method, modified to account for an extra leap year day, to produce the intercensal population figures that will be used until Census releases its official intercensal population data.
