All right. Here's what I've come up with. I've separated things into two sets of numbers -- one set covers thorps, hamlets and villages; the other covers towns, cities and metropolises.

57% of adult population = Number of total buildings found in community.

Thorp, Hamlet, Village
Residences -- 59%
Farms -- 32%
Shops -- 3%
Industrial -- 2%
Entertainment -- 2%
Administrative -- 1%
Nobility -- 1%

Town, City, Metropolis
Residences -- 27%
Residence/Business -- 13%
Shops -- 11%
Slums -- 10%
Industrial -- 9%
Services -- 9%
Entertainment -- 6%
Administrative -- 5%
Nobility -- 5%
Farms -- 2%

Support Values for Businesses and Services according to population numbers are still being worked on. Not liking how some of the figures are coming out for thorps and hamlets. Particularly thorps.
