Population happiness

The default population happiness level is 0. This number is affected by several factors:


 * Population desired religion vs actual national religion.

 * Population density – Citizens like room to stretch out.
 * Size and strength of military – Citizens like to feel protected.
 * Military casualties – Casualties increase war weariness.
 * Military deployed – Too many deployed troops also increases war weariness
 * Infrastructure level – Infrastructure helps increase happiness.
 * Government tax rate – Citizens prefer to pay lower taxes.
 * Nation age – Citizens prefer the stability of older nations.
 * And a couple of hidden factors as well

The most important effect of population happiness is a nation’s daily population income. The happier your citizens are, the harder they work and the harder they work, the more money you’ll have to improve your nation.
