Corruption Index

A nation's corruption index is the measure of the integrity of the government. Corrupt governments are inefficient and are less prosperous economically.

Default Rate of Increase
Corruption automatically increases at a base rate of 0.01 / day.

Corruption Cap
Every nation has a "corruption cap" based on its population. This prevents the corruption index from both increasing too quickly and getting too high for nations with smaller populations.

Anarchy
Nations without a constitution will have their base rate of corruption doubled, adding 0.02 / day.
