Each of the dozens of commanderies available in Total War: Three Kingdoms is described by a number of attributes - the amount of gold obtained through taxes, generated and consumed food, the garrison protecting it, as well as the population factor. One of the key problems connected with population and development is population overgrowth known as overpopulation. In this section we have explained the overpopulation issue, where it comes from and how to deal with it.
Overpopulation - what is it and where does it come from?
First, it is necessary to explain to yourself what is the population in Total War: Three Kingdoms. It's just the population inhabiting a specified commandery. This value depends, among other things, on the amount of gold mined and the rate of renewal of nearby armies - the higher the population, the more gold will affect the commandery. Also, resources of the army (stationed there) may replenish much faster. If the economy of faction or commanderies is not fluctuated, the population will grow with each turn.
However, each Commandery has its own upper limit of population that it can reach. This is closely related to the level of the main building in Commandery, that is, the Settlement Administration - higher it is, (in addition to other benefits) higher the population level may become. If don't develop this structure enough in advance and the population level is going to be equal with the limit, the commandery will be overpopulated. Commandery will receive that excruciating penalty to the level of public order that will last until the main building gets upgraded and the maximum value of population gets increased.
How to deal with overpopulation?
To cope with overpopulation, you need to remember two things: raising the level of the main building within the commandery, as well as reducing the fast population growth. The expansion of the building is behind us, we need to focus on reducing the rate of population growth. The growth gets increased by the construction of appropriate buildings within the commandery - if you are not planning to expand the main building too quickly, or there are problems within the commandery with maintaining the population, refrain from building this type of structures, and if so, think about demolishing them. It is also worth considering the construction of structures that reduce the level of population growth - this will let you save other buildings, which often give other tangible benefits, while maintaining the level of population growth at the stable level.
The main thing, however, is to constantly monitor the level of population in each available commandery and plan the stock, as updating the main building to increase its maximum level just takes a few turns. It is also worth to see the level of population growth for this commandery - it is enough to choose a commandery and look at the lower left corner of the screen, where there is information about the current population and the change in the next turn.
