The population of your country in supreme ruler 2020 is very interesting, as it both effects how much money a country makes, and its military reserves. The fastest way to increase your population, is to engage in war with other countries, and conquer their territory. Wars can be costly however, and there is always the risk that you will not be able to make it. You should therefor make sure, that you are ready, before starting any wars.
A more peaceful way to increase your population, is to increase your social spending. This can directly effect birth and death rates, as well as the emigration and immigration values of your country.
There are some things you can do, to increase your population growth. These include increasing the following values:
- Health Care
- Family Subsidy
- Social assistance
The direct effect of making changes to social spending, may not be clear until several days after making the changes. Which makes it difficult to experiment. However, some "obvious" things that the different options controls, could be as follows.
The effect of social spending
Increasing health care should effect both birth rate and death rate, in a positive way. That is, the birth rate should increase slightly, and the death rate should decrease significantly.
Increasing family Subsidy should increase birth rates significantly, and perhaps have a minuscule effect on death rate.
Increasing social assistance should likely lower both the emigration and immigration of your country significantly.
