Census results show Iowa keeping all four congressional seats
Iowa will retain all four of its seats in the U.S. House after preliminary data from the 2020 Census show Iowa with modest population growth of 3.6 %.
As more detailed Census data is released, Iowa lawmakers will be required to vote on new congressional and legislative districts that become effective for the 2022 election. Iowa has an often-praised, nonpartisan process for drawing new political maps. Most of the work is left to computers, which will draw new district lines to create 50 Iowa Senate and 100 Iowa House seats, along with four districts for U.S. Congress.
The Des Moines and Iowa City metro areas had the fastest growth in population and are expected to gain new legislative seats, while most rural parts of the state continue to lose residents.
