Is growth scale must in a long game?

[Argitoth]

I can tell you why a random event for an increase of population is plain unrealistic.

First of all, if there was an increase in population, it would mean there was more babies born this month than usual. That's completely unrealistic. More population = more population. There cannot be a random even for population growth. Even if there was a sudden increase of population, do you really think 1-month old babies can pay tax?

The only realistic event for population growth is immigration.

Immigration can be good or bad. Population increases or decreases in a province you own while decreasing or increasing in a province you do not own.
