Particularly check out the change over the last year. Note that the manufacturing filter and the housing boom, generally, do not coincide. Also, areas of no change seem to be predominantly rural. Exception is Wyoming, but the cities in Wyoming are so far isolated from anywhere else, they might as well be rural! I think the rural areas that have seen little change would likely be generally more self-sufficient, and be net exporters of human capital. Some, like West Virginia, might even get a boost, as tourism might increase from neighboring states, as people in those states stick closer to home.
