Population is the lifeblood of your empire, used to grow your cities to collect powerful rewards and create more units.
Underneath each city is a segmented bar. It's the surplus that indicates how much population your cities require in order to level them up. The dots within the segments indicate how many units that city is currently supporting. You cannot have more units than the segments.
Increasing the total population of cities is essential in establishing a strong economic backbone for your empire and to sustain a proper army for both offensive and defensive operations.
To gain more population for a city a number of things can be done:
|Action||Population Growth||Stars spent||Growth to Stars ratio||Technology needed|
|Temple (All except Forest)||1||20||0.05||Aquatism/ Free Spirit/ Meditation|
|Roads||1 when connecting a city to the capital||2 per road||varies||Roads|
|Sawmill||1 per adjacent Lumber Hut||5||varies||Mathematics|
|Windmill||1 per adjacent Farm||5||varies||Construction|
|Forge||2 per adjacent Mine||5||varies||Smithery|
Here are all the rewards for upgrading a city:
- Level 2 City: Workshop or Explorer
- Level 3 City: City Wall or Resources
- Level 4 City: Population Growth or Border Growth
- Level 5+: Park or Super Unit
Once a city in your empire reaches level 5 for the first time, you will unlock the Park of Fortune monument.
Negative Population (Anti-Food)
If a city ever loses population (i.e. a city disconnected from the capital, a Nature Bunny crushing a building, destroying a building) and your population bar is empty, a red-colored segment will appear in the population bar. Each red segment removes 1 star from your production. It is not possible to make less than 0 stars per turn. You can still support Units with red segments.
If your bar fills up with red dots, your production for that city will stop completely. Should you continue to lose population, the bar will begin to shrink, and you will no longer be able to support as many units.
If you were to regain the population, you would have to first remove the red segments before creating blue segments again.
NOTE: This is likely a bug, but if you make the bar disappear entirely, it will become impossible to make it reappear.
