Territorial division: the least-time constraint behind the formation of subnational boundaries
Abstract:
Nations usually locate their smaller administrative subdivisions in regions of highest population density. This report derives a precise form of the size-density relationship from the general assumption that social structures evolve in such a way as to minimize the total time expended by society in their operation. The result is confirmed empirically.
