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.

Morale Building Specifics

Morale buildings use special volume types in the building blueprint to satisfy citizens. In the Construction menu they are quantified as "Professional Jobs".

The need for cantina and retail store professional jobs is special, in that it can be fulfilled by any building types as long as the building blueprint has lounge or store volume allocated.
