I was trying to come up with numbers and such for my campaign in terms of populations and city sizes. I ran across this link - its fascinating!

Figured I would pass it along as it directly relates to folks trying to create fanciful maps, and it might help to have a bit of perspective on populations, city sizes, number of cities, and amount of land devoted to farming to support each city.
