The actual data there is for all large metros and what it does indeed show is an estimated net migration of 'millennials' into the Pittsburgh region. Not the largest of flows, but comparatively not bad as per Frey's benchmarking. For certain not bad when compared to Pittsburgh past across most any past time period which saw persistent negative net out-migration. This supports my belief that we are now* into our 6th year at least of net in-migration of younger working age population. So young folks voting with their feet are landing in Pittsburgh. I'll append a little more later if I have time.
