What resident population did the 2020 United States census record?

The 2020 United States census recorded a resident population of 331,449,281.

This figure counts people living in the 50 states and the District of Columbia on April 1, 2020, the official Census Day. It excludes the separate overseas population used in some apportionment calculations. The count was the 24th decennial census in U.S. history and was conducted during the COVID-19 pandemic.

The total represented an increase of 22,703,743 people, or 7.4%, from the 2010 census figure of 308,745,538. That was the nation's slowest percentage growth in any decade since the 1790 census, when comparable historical records began.

A common mix-up is confusing the resident population with the apportionment population. The latter includes certain U.S. citizens and federal personnel overseas, while 331,449,281 is the standard resident count. The census results were used to redistribute seats in the House of Representatives and to guide redistricting.
