Iowa is a great state. The college towns and Des Moines (the capital) are as fun and forward-thinking as any other state's college towns I've been to, and cost of living is hard to beat.

Not sure if that has anything to do with it but I don’t think it helps.

Heck, the two cities are only a half million between them; the "metropolitan area" constitutes over EIGHT THOUSAND square miles for a grand total of a little over three million people. Traffic- cars, busses, and light rail- are all here to stay, and that means walking city streets is only as nice as you enjoy breathing exhaust fumes and the noise of tires.
