The city population of Memphis is larger than Nashville, but the metropolitan area population of Nashville is much larger than Memphis. Nashville is quickly catching up with Memphis in city population and will probably will overtake Memphis in a few years. The urban area of Nashville is also much larger than Memphis. Having lived in both cities, Nashville has more diversity. I could go to Boricua Cafe or La Casita to get some real Puerto Rican food...couldn't find that kind of stuff in Memphis.
