Population growth increases the population of a city by three. It is one of the rewards for upgrading a city to level four (the other being border growth) and is also a ruin reward. As a ruin reward, population growth gives population to the capital city. Population growth cannot be granted by a ruin if the player does not own any capitals; however, if the player's own capital has been captured but the player owns other capitals, then the population will go to the highest level capital.
