Yeah, what both you guys have said re cities being regional areas was going to be my comment; but also noting that districts had jarred that a little. I've read 'Why the West Rules...for now"; and he presents evidence that would agree to an extent with the OP. I think, from memory, it was a bigger factor though as cities exploded with the industrial revolution. At least to begin with. A city alone sustaining it's own population is very much a modern thing; but as cities in Civ have farms etc, they realistically represent a province of sorts rather than just the city itself. Egypt. Kinda It was Civ III as historix69 says.
