Medieval Demographics Made Easy

This reference guide provides estimates for the populations, settlements, occupations, and social structures of medieval and fantasy realms. It helps determine how many people live in villages and cities, and how farmers, merchants, nobles, guards, and other ordinary inhabitants support an adventuring setting. The guidelines can be applied to grounded medieval worlds as well as more elaborate high-fantasy societies.
