This is affected by the following factors:
- type of planet
- Every planet provides other conditions of living. The better they are, the higher the population growth is.
- population
- The more people there are, the more can procreate, hence the higher the population growth is.
- infrastructure
- The better the infrastructure is, the happier your people are and hence the higher the growth of population.
- trade center
- The more important money gets, the less the growth of population is.
- living space
- Whether you're always in the other's way (too little living space) or you rarely see anyone around (too much living space) - it's not good for the growth of population.
