2020 Census Population Counts for Apportionment

submitted by Ottawa County

On April 26, 2021 the US Census Bureau released the 2020 Census Apportionment Results which include new figures for state resident population counts, apportionment population counts, and overseas population counts. This post contains a summary of the population count updates and apportionment updates. Apportionment population results are used to calculate the number of seats in the US House of Representatives to which each state is entitled.

According to the new population count data, Michigan has gained 193,691 residents since 2010 ā€” a 2.0% increase ā€” for a total population of 10,077,331 residents. Because of the population increases in Georgia and North Carolina, Michigan has dropped from the eight most populous state in 2010 to the tenth most populous state in 2020.

Despite a gain in resident population, the increase in other states’ populations will result in a decrease of 1 seat for Michigan in the House of Representatives for a total of 13 seats.
