Census 2020 Count for Massachusetts
On April 26, 2021, the U.S. Census Bureau released the Census 2020 apportionment data, including the resident population, overseas population, and total population enumerated for each state in the 2020 decennial Census. State total population counts, including overseas population, are used to apportion congressional seats among the 50 U.S. States while resident population counts (excluding overseas) are used to determine the population in each sub-state legislative district. This state-level apportionment data represent the first official population numbers coming out of the 2020 Census count for Massachusetts.
