Many major cities have started seeing growth again. But it's usually still below the nationwide growth, and the growth seen in the suburbs, so they'll generally lose CDs again. You mention how DC grew 5%, the first time it's seen growth in a long time. Notable, but the nation grew 10%. If it were part of Maryland or Virginia, a DC-based district would have had to expand into the suburbs.
Yes, but it's usually worse than this.
D.C. has pretty much a fixed boundary and was already pretty well built-up, but what about other big cities?
Somebody said that Louisville and Lexington together now make up a much larger proportion of Kentucky's population (even if you adjust Louisville for merging with the county). I'm wondering how close it'll be to bringing Kentucky back into the Democratic column.
Even if the cities were to grow faster than the suburbs that wouldn't necessarily make more democratic. people probably won't vote for a different party just because they moved, it could be that people that moved to the city were predisposed to vote for the democrats even before they moved to the cities. Conversely, it could be Republicans moving from the suburbs but they will just keep voting republican which would simply make the cities more republican.
