Morale decides whether a city gains or loses citizens. It ranges from -20 to +20. Every city cycle, all the morale bonuses and penalties are added together, and the total morale is increased and decreased by this amount. Every morale point above 0 causes 1 citizen to immigrate to the city. Conversely, every morale point under 0 causes 1 citizen to emigrate from the city. Cities in harsh environments immigrate and emigrate only at half the normal rate.
