Yes, demographics. How many buildings are needed for a total community population. A subject I find very fascinating. And not just the number of buildings, but types of buildings and services.
Been working on some numbers for figuring this out and will be making maps according to those numbers. Hope to have these percentages finished up this evening.
The most complex one I'll be doing is of Carnd a city-state. Has 135,000 adults living there and is a port city as well. Several occupied islands are also part of the city. There's even a sea elf colony living near the harbor. I'll be mapping that as well.
