# City Size - > Real Life Correlations

I was wondering if anyone has a list of what size city in Civ3 equals its real life population counterpart. I'm wanting to make a real-life based scenario, but I don't want to make the cities too big nor too small.

I believe that you multiply the number that you see as the city's size by 100,000 or something. Yes, 100,000 is what I think it is, although I could be mistaken.

100,000? O.o

I guess that makes some sense, especially modern-wise... although in the early ages, it seems a bit big.

I don't think that is right. I don't know the exact sizes, but I know that size 12 is about 800,000-820,000 people.

That puts it somewhere in the range of 68,000 people per number.

It would be far more realistic if it was more of an exponential thing, though.

Each population point is worth its number * 10,000, but the effects are cumulative, ie pop point 1 = 10,000, pop point 2 = 20,000 PLUS pop point 1, etc. And the additional population is calculated with the amount of food you have towards growth, so pop 2 with 9/20 food has 10,000 + 20,000 + 30,000 * 9/20 = 43,500 population.

Ahh, yes, that would make much more sense. The designers of Civ would not want to make it too easy, now would they? I mean really, they can use some big long complicated math equation, employ those math Geeks (only joking) Is there a list of what City sizes equal? Or a calculator?

I wouldn't worry too terribly much. Most cities in the city list for say, Rome, would be sizes 1-4 while Rome itself was size 12-14. Just do it in relation to the game scenario, not real life.

The population of a city in civ of size n is sigma n for i = 1 to n, multiplied by 10K.

A city size 3 would be 1+2+3=6, or 60K
A city size 10 would be 550K
A city size 15 would be 1.2M
A city size 20 would be 2.1M
A city size 30 would be 4.65M
