How do I find out what to put as income for a city.

Alright so i'm looking for some kind of formula for this. The map is a default sized Europe map. I don't want the incomes too high or too low. I tried dividing the population of the province by the population of the city and vice versa but that didn't work. Any other ideas?

^ This. Doing the income like that makes for a fairly playable map. Now to get the 'GDP' for each individual city, you can do what the admins did. They looked on Wikipedia for the GDP for a whole country, then divided the population of the city by the population of the country and multiplied by the country's GDP. So for example:

GDP of USA= 15 Trillion
Population of USA= 311 Million
Population of New York = 8 Million
New York / USA = 2.57%
GDP of New York = 385.5 Billion

At which point you can scale as shown in Runway's topic. If you give me a list of all the cities you want 'GDP' for and what you want the highest income of a city to be, I could probably help you calculate the incomes. The highest income in the default map, Tokyo, is 559. New York is 365.

I'm looking for some help building the income for a massive star trek map, I have most of the major player cities set. I was hoping I could get a more experienced map builder to do the income and reinforcement for the map.
