There was an interesting new post on the subject written by Greg Giroux and published at Bloomberg Government. Take a look at this excerpt:

A months-long delay in the release of state-by-state congressional reapportionment and census data is complicating how political candidates and party organizations prepare for the 2022 House elections.

Beset by holdups, the U.S. Census Bureau won’t release the once-per-decade state population totals and how many House districts each state will have for the coming decade until April 30. That’s four months after the statutory deadline, and even that date is fluid.

Meanwhile, the detailed, block-by-block population data that state legislatures and redistricting commissions need to redraw congressional lines won’t arrive from the bureau before July 30, months later than at a comparable point in 2011.
