Citizens are the people that live in your town. Together they form your population. You can see your town's current and maximum population by going into the Town hall view, as well as on the Main Menu of the User Interface. They work to produce goods and pay taxes to give you Gold — they are the heart of your town.
A "free" idle citizen increases your income by 3 per hour. A working citizen has no overall effect on your funds, but produces goods. However, a scientist decreases your income by 9 per hour ( −3 for the loss of a citizen and −6 for scientist ). A town with a growing population will therefore see rises in income if its citizens are not put to work immediately.
Establishing a new colony requires sending 40 to as its initial population.
Growth rate is determined by the happiness score of a town; generally, a higher happiness to citizen ratio gives a higher population growth rate. Without increasing the happiness score, each additional citizen slightly decreases the population growth rate until a growth rate of zero is reached.
A local Tavern or Museum can raise the happiness of the town it is built in. A high growth rate leads to the maximum number of citizens quicker, allowing you to gather more resources per hour at a faster pace, which is highly desirable. However, this can be quite costly.
The maximum number of citizens at any one time is limited by the number of Housing Spaces which increases with each level of the Town hall. It can be calculated using formula
