City Morale

City Morale determines how citizens migrate to or from a city. Positive morale attracts new citizens and causes higher birthrates, while negative morale drives them away.

Morale modifiers have instant effects, with the sum of their effects being visible on city reports. This makes it possible to see immigration and emigration in the same report.
