Redistricting Projections

Leaving aside for a moment the political football that is gerrymandering, here is an updated projection on which states will need new districts. The source:

States Gaining Districts (7)
Arizona +1 (from 9 to 10)
Colorado +1 (from 7 to 8)
Florida +2 (from 27 to 29)
Montana +1 (from At-large to 2)
North Carolina +1 (from 13 to 14)
Oregon +1 (from 5 to 6)
Texas +3 (from 36 to 39)

States Losing Districts (8 or 10)
Alabama -1 (from 7 to 6)
California -1 or even (from 53 to 52 or no change)
Illinois -1 (from 18 to 17)
Michigan -1 (from 14 to 13)
Minnesota -1 or even (from 8 to 7 or no change)
New York -2 (from 27 to 25)
Ohio -1 (from 16 to 15)
Pennsylvania -1 (from 18 to 17)
Rhode Island -1 (from 2 to 1)
West Virginia -1 (from 3 to 2)

New York's long decline continues, while no income tax states gain big. Applied to the 2016 election results, Trump would gain either 5 or 7 electoral votes.

This is starting to shape up. UVa did an article on apportionment for the 2022 House elections. normally the results of the census would become final by the end of this month. Due to COVID, that date has been put off to end of September. Among other consequences , several states have court orders allowing additional time to prepare maps.

For the first time in history, California will lose a seat in Congress. As you can see, the 2019 estimates in OP were pretty close. The expected net effect is that five to seven seats swing from Democrat to Republican. That's more than enough to tip control of the House.

There is a nice map.
