The 2020 Census figures will come out in a few months, and will affect multiple states in Congressional representation in 2022 and beyond, as well as the Electoral College.
A number of the larger populated states will continue to lose representation and electoral votes, as they have faced for several decades.
This includes New York, Pennsylvania, Ohio, Illinois, and Michigan, but also California is likely to lose a Congressional seat and an electoral vote for the first time ever in America history. Also, West Virginia, Rhode Island and Minnesota are likely to lose a seat and an electoral vote.
The states which will gain include Texas, Florida, North Carolina, Arizona, Colorado, Oregon, and Montana, with Texas and Florida gaining the most.
Montana will move from one statewide House seat to two, while Rhode Island will move from two seats to one, so Rhode Island will join Vermont, Delaware, Alaska, North Dakota, South Dakota and Wyoming as the seven states that have only one House member for each state.
