Texas gained two congressional seats while seven states lost a seat following the 2020 census. In all, seven seats shifted between 13 states.
The Census Bureau made the official 2020 state population numbers public on April 26. With that release came reapportionment, which uses a formula to redistribute each state's share of the 435 House of Representative seats starting in the 2022 midterm election. That formula takes state population into account. The changes in apportionment will have a political effect, notably in the Electoral College, where states are allotted electoral votes based on the number of members in Congress.
State redistricting comes next. By September 30, the Census Bureau will have provided each state with more granular population data separated into geographies like counties, cities, American Indian areas, census blocks, and voting districts. Any state allotted more than one representative will have to draw new maps splitting their states into geographic areas with equal populations. Each state's process and rules are different, with some of the maps drawn entirely in the legislature and others developed by independent commissions.
Which states gained and lost seats
In addition to Texas gaining two seats, five states gained one seat: Colorado, Florida, Oregon, Montana, and North Carolina. Seven states lost seats: California, Illinois, Michigan, New York, Ohio, Pennsylvania, and West Virginia.
