What Is Apportionment?

It's the process of determining how many seats each state gets in the U.S. House of Representatives.

There are 435 seats in the U.S. House of Representatives, and every 10 years, census results are used to calculate how many seats each state gets.

On April 26, 2021, the Census Bureau delivered 2020 Census state population counts that will be used for apportionment.
