The Census: Mapping 90 years of shifting population and power

Everyone knows population–and political power–has shifted from the Northeast and Midwest to the West and South, but an interactive map by The New York Times offers a vivid visual demonstration. It’s based on Census figures from 1920 to the numbers just released Tuesday. The map details changes in Congressional apportionment, but that’s a good stand-in for population change as well.

Meanwhile, Politico looks at the impending redistricting fights with a particular emphasis on those states where the infighting could be the nastiest: the nine states that are losing seats, prompting possible incumbent-vs-incumbent battles. Two are next door–Massachusetts and New York.
