The Census Bureau has delivered its annual Christmas gift to demographic junkies, its estimates of the populations of the 50 states and the District of Columbia for mid-2015.

They show where the nation has been growing since the April 2010 Census head-count, a period that follows the end of the 2007-09 recession and includes three-fourths of the Obama presidency. They show what states Americans have been moving in and out of, and what states have attracted the most immigrants.
