Credit to S. John Ross. for all the calculations. See http://www.io.com/~sjohn/demog.htm for his article and credits.

People per square mile:

Width of the MC (Map Component):

Shape of the MC (Map Component):

Number of MCs (Map Components):

Urban Percentage:
( 1 - 8 )
Percentage of Wanderers / Itinerant Workers / Isolated Settlers:
( 2 - 5 )

CALCULATIONS ARE SHOWN BELOW:



Square Miles in MC
Square Miles of Kingdom / Region
Population of Kingdom
Urban Population of Kingdom
Wandering Population of Kingdom
Suggested Largest City (Semi-Random)

Notes: Each additional city is 10% to 20% smaller than the one before it, until the 8000-12000 size range of cities is hit. After that, there may be one or two small cities, with the rest of the urban population being towns. This model may break down with very small countries. Test to see.

Other Tasks: 1) Automate smaller city creation steps 2) Check for form entry errors 3) Give the page an actual look and feel
