Such a crap list. The bigger the city, the worse it is. Suburbs to big cities are not good. Cities on the border are not good.
I’ll just take one, Texarkana, TX. No a problem, decent place to live, much better than any of the top 50 cities.
These lists are like a shotgun shooting shells of bs.
Also the reasons why the author thinks they are miserable cannot be found in Census data. Back in the day, claims like these were called academic fraud.
