I thought I would point out a few cities that would dispel the theory that great cities have great statistics backing them up. In fact, in several instances, great cities have pretty average statistics backing them up. The following information is from CityData.com. I've compared back-to-back Portland, Charlotte, Austin, Omaha, OKC, and Tulsa. They're all pretty similar, in fact no city has a clear advantage over any other, except in population, where Portland is clearly a lot bigger than Omaha and the rest just fill in the spaces. I was especially surprised by how high crime is in Portland and Charlotte.
