The migration spotlight is on the 25-34 cohort, the after college relocation and the war for talent. Riverside, Phoenix, Atlanta, and Charlotte drop off the map post-Great Reset. Their top gainers replacements are the usual suspects (i.e. DC, Denver, Seattle, and Austin). No surprise there. The migration boom towns are yielding to brain magnets.
The young and well educated were able to move during the economic downturn. They clustered in the cities already awash in the young and well educated. Talent attracts more talent. As the economy improves, other migrants should become hungrier for risk. I doubt Riverside, Phoenix, Atlanta, and Charlotte get back on the map.
I predict Pittsburgh will absorb a good chunk of that slack. We'll see more Buffalo-to-Steel City instead of Buffalo-to-Charlotte. Detroit-to-Pittsburgh is a flow to watch. As for return migration, Charlotte-to-Pittsburgh is already a trend (anecdotally speaking).
Thanks in part to the shale gas revolution, the stars have aligned for Pittsburgh. The positive press is now credible. Forget eds and meds. Pittsburgh is town and gown. Town and gown means plenty of tech and talent. There's no longer a black hole between NYC and Chicago.
