America is going through an "extreme makeover"—at least in terms of diversity, according to WalletHub, which took a peek at which major metropolitan areas rank highest in this regard. The site looked at more than 500 of the nation's biggest cities, scanning more than a dozen metrics in five diversity categories: socioeconomic, cultural, economic, household, and religious. Maryland claims the top three diverse cities on WalletHub's list, with Gaithersburg coming in at No. 1. The least diverse city in the rankings: Brattleboro, Vermont.
