Key Evidence
The Census Bureau reported a resident population of 331,449,281 for the 50 states and District of Columbia as of April 1, 2020.
The Bureau’s official apportionment materials identify April 1, 2020 as the measurement date and distinguish the 50-state-and-District-of-Columbia total from Puerto Rico’s count.
Later population estimates treated 331,449,281 as the April 1, 2020 census baseline, rather than as a current population estimate.
