If only I had time.. I really need to do this for Pittsburgh. See this detailed interactive map graphic Forbes has just put up of migration data
for major metros in the nation. Most have seen it, but our latest report based on the same data that underlies that graphic is online here
just fyi. Same stuff, just not as neat a presentation.
oh... half nevermind.. It isn't just for those major metros listed.. You can do it for all counties if you poke at it.. But I guess it's only compiled by metro for a few areas.
