The blended base is the estimate of the national, state, and county populations by age, sex, race, and Hispanic origin as of April 1st, 2020, that the Census Bureau has used in their population estimates since the 2020 Decennial Census. The blended base uses population totals from the 2020 Decennial Census, but the distribution of the population by age, sex, race, and Hispanic origin comes from other data sources.
