Under most systems of government, the corruption and waste experienced by a city increase with distance from the capital. The formula:
Corruption = ((Trade x Distance) x 3 / (20 x (4 + Government))Where:
|0||Communism and Democracy|
Distancethe city's distance from the capital (diagonal squares count as 1.5 squares). The maximum value of Distance = 36.
GovernmentGovernment + 1, if the city is celebrating "We Love The * Day".
Distance(Distance x 2) + Difficulty Level (possible values = 0 through to 5), if the government is Despotism.
Corruption = Trade x DistanceFactor * TenTenFactor / 100
Waste = ShieldSurplus x DistanceFactor * TenTenFactor / 100The results are rounded down. TenTen factor depends on the government and represents the corruption/waste in a city with trade=10 at distance 10 from the capital:
|Despotism||3= 15/5||3= 5/5|
Communism may be changed in rules.txt file; by default the file contains the following line: 0 ; Empire is equivalent of this palace distance.There is no tax and beaker output under anarchy and so the corruption is irrelevant.

|Road to capital||-||2/3|
Any city with a Palace in it (the "capital" ) will have no corruption or waste whatsoever.
