Aren't most Americans from Europe and Africa (having displaced the original American Indians)? Aren't modern Americans now both scattered across the US and, yet, in cities?
It's not exactly the same thing, I know, but it does demonstrate that people multiply and scatter (but in clumps, if you will).
Hope that helps.
