Population is the amount of people that live in your settlement. The population creates most of the gold in an Empire in form of taxes. More population means there are more people to pay taxes and thus you'll get more gold off your citizens. As you advance in the game you can research different types of taxes to get more gold from your citizens.
Population of a settlement can be increased by building/upgrading structures in your settlement. However, some buildings such as Trading Post do not add population. Storehouse is one of the best options for population boosting, adding 20 per level and also allowing you to store extra resources. The Great Aqueduct also adds 25% more population to your capital.
The population bonus of various buildings are given below:
