Population is increased by the number of cities and the number of zones each city has.

Zone Type                          Population Increase
City (Base) 100
Residential 10,000
Commercial 2,400
Industrial 2,600
Civic 4,000

1,000,000 (for every 1,000,000 sq km)

Because a new city has one of each zone, a new city starts with a population of 19,100.

The max number of zones a cities can have, with a max land area of 5,000,000 sq km provides each city with the opportunity of a maxed population of 195,000,100 people.

Certain events increase your population. This does not increase the number of citizens in your city, but does change your national population.
