Decennial Census: Wisconsin Retains its Eight Congressional Seats & Gains 3.6% Population


The U.S. Census Bureau recently released the congressional apportionment population counts and number of representatives for each of the 50 states, along with the resident population counts for the nation, the 50 states, the District of Columbia and Puerto Rico.

Wisconsin’s 3.6% population increase (206,732 residents) was in line with rest of the Midwest. The population gain will not have an impact on our representation in Washington. Wisconsin will remain at eight U.S. Congressional seats.

“Ensuring an accurate population count in the decennial census is vital to the future success of a state because we need to be making decisions with accurate data, most noteworthy, the determination of a State’s representation in Washington,” said MadREP President and CEO Jason Fields. “I’d like to thank everyone in the Madison Region who filled out their census forms and encouraged others in their community to do so.”

Thirteen U.S. states will experience an adjustment in representation. Texas will gain two seats in the House of Representatives, five states will gain one seat each (Colorado, Florida, Montana, North Carolina, and Oregon), seven states will lose one seat each (California, Illinois, Michigan, New York, Ohio, Pennsylvania, and West Virginia), and the remaining states’ number of seats will not change based on the 2020 Census.

The constitutional basis for conducting a census of the population every 10 years is to reapportion the U.S. House of Representatives. Apportionment is the process of distributing the 435 memberships, or seats, in the U.S. House of Representatives among the 50 states based on the apportionment population counts from the 2020 Census. An apportionment has been made by the U.S. Congress based on each decennial census from 1790 to 2020 except for the 1920 Census.

The apportionment population consists of the resident population of the 50 states, plus the overseas federal employees (military and civilian) and their dependents living with them who could be allocated to their home states. The population of the District of Columbia is not included in the apportionment population because it does not have any voting seats in the U.S. House of Representatives.
