Just in case anyone is thinking about statehood, I've decided I should make some hypothetical maps for Washington, D.C. and Puerto Rico. (Someday, in September, when we have data.)
NPR reports that the US Census Bureau might not release redistricting data until September 30, long after the usual dates in February through April, or the previous delayed estimate of July. BDistricting's fully automated approach should be just fine though. In a crunch we can rent a bunch of cloud servers and have good results for any state as little as a day after the data is available.
The 2020 Census data for redistricting is immanent starting around 2021-01-19, but we don't have official reapportionment yet! The last report from the Census bureau was "early 2021, as close to the statutory deadline as possible". If they don't have proper apportionment out by the 19th, I guess I'll start my redistricting engine based on estimates (or this estimate, or others, or some consensus I put together).
