When putting together some of the cities and towns in Dragon Heresy, I used an article by S. John Ross called Medieval Demographics Made Easy.
It’s pretty much what it says on the tin: a tightly-presented metasystem and consolidated research finding on the population of medieval towns, villages, and cities. It provides die rolls, tables, and other necessities to quickly understand how many of what profession are going to be in a given place, as well as talking about castles, agriculture, and more.
When S. John restructured his website, The Blue Room, it became convenient for him to offer this file to host on other blogs, and I asked if Gaming Ballistic could be one of them.
I intend to keep using this for Dragon Heresy, and I recommend it strongly, if for nothing else to avoid the trope of medieval villages that feel like 21st century suburbs and strip malls.
