I got a little bored today and decided to explore the civ 4 population demographics. When the mouse cursor places on top of the city number, it displays the real world pop. I do this for a city from size 1 to 80 and find an approximate model that converts civ 4 pop to real world pop. The model is:
Real World pop = 950.2*(Civ 4 pop)^2.8081
Using excel, the reduced chi-square is 1.000 to 4 sig fig. The error is largerest for the smaller city size, especially size 2 city w/ 10% error, and between 3 and 4% for city size 3 to 12, 2 and 3% for city size 13 to 45, and 1 and 2% for city size 46 to 80.
As an example, New York City has a population of 8,363,710 as of July 2008 according to the US Census Bureau. In terms of civ 4 pop, it has a city size of 25.39. If we round up the decimal, then the city size of New York City is 26. The Census Bureau only lists US city w/ population greater than 100,000, which is size 6 (rounded up). It is suprising that only 15 US cities are above city size 10, and only New York City above 20. Appearantly not enough people are available to work all 20 tiles in the city radius. However, one must also take into account the land area of those cities, but I wont be discussing here.
One interesting result from this is to find out the real life US representation in civ 4 UN election. In the simplest model if we only consider US as one city, then US would have a minimum of 92 votes (round up) in the UN (the current US estimated pop is 3.084e8). China and India, the two most populous countries have pop 1.335e9 and 1.175e9 would have a minimum of 155 and 148 votes in the game UN. Portugal, a country w/ pop 1.064e6 would have at least 26 votes. The game voting system definitely favors smaller cities than larger ones. Since I dont know the statistics for land area and how to set the boundries, I cannot give the most accurate UN votes for real world countries. I'll let the people in the forum to set the boundries.

It also got wall street so most great merchants are probably settled there for some extra food.
