Few big surprises here, although Detroit is pretty jarring in its loss of residents each morning. As a rule, cities that import workers, and/or have local jobs for most of their residents, are generally better off economically — with the notable exception of Washington, DC, since it gains little tax revenue off the jobs it hosts.

Since that list turned out to be 35 cities, here are the top 35 cities (with daytime population over 30,000, the size of a good-sized Edge City) ranked by the percentage increase in their daytime population:

*Bold* cities are the few on this list that qualify as (small) central cities. _Italicized_ cities are Edge Cities whose “host” cities don’t appear on the first list. Note the presence of multiple Detroit and St. Louis suburbs here — the super-winners in their bloody metropolitan games, with plenty of jobs to profit from and few residents to take care of — and the number of LA suburbs also listed, relative to other metros of its size. Upon first glance, many of these importing cities are Edge Cities, tourist meccas, or industrial hubs (the original Edge Cities).
