@James Ong, please have a look at the following link:https://www.governing.com/gov-data/census/state-mi...Loser States:IllinoisOhioNew YorkNew MexicoMississippiVermontWisconsinAlaskaMichiganALL of the above states had net LOSSES in migration over the period studied, which was 5 years.  

Have seen Wilmington permit requirements migrate through the years and get, in my opinion, a little crazy, almost to the point that some investors avoid doing projects there.Towns like Elsmere, DE and some small towns & townships in Delaware County, PA seem to almost count on permitting fees to help them survive.

Despite all the headwinds the city faces, I really believe Chicago is a big winner in 15-20 years to climate migration.
