Manpower

A nations' manpower is its men eligible for military service that are used to create and reinforce armies.

Maximum Manpower
Maximum manpower is a sum of your provinces' manpower pools, where that pool is derived from class manpower of each classes in each province. Manpower tax determines how much of each class are extracted as manpower. All nations have a base of 3000 maximum manpower.
 * $${\text{maximum manpower} = (3000 + \sum\text{province manpower} + \text{HRE adjustment}) \cdot \text{national manpower modifiers}}$$

Provincial Manpower
Provinces gather manpower from eligible men in their population.
 * $${\text{province manpower} = \sum\text{class eligible manpower} \cdot \text{provincial manpower modifiers}}$$

Class Manpower

 * $${\text{class eligible manpower} = \text{class population} \cdot \text{class eligibility}}$$

Manpower Recovery
State manpower recovery can be seen as actually flexing your administrative muscle to keep track of people who should be raised as levies by right. Class manpower, on the other hand, can be seen as demographic recovery where new people are born to fill up the place of the deceased. When class manpower is below its maximum amount, it will automatically regenerate.


 * $${\text{monthly manpower recovery} = \frac{\text{maximum manpower} \cdot (1+\text{manpower recovery speed})}{120}}$$

Class Manpower Recovery Speed
Class manpower values are calculated using the classes' respective manpower percentages. These percentages are modified by the game whenever the classes' actual manpower values need changing. The percentages change over time according to the following formula:


 * $${\text{class manpower recovery} = 1 - (\frac{\text{class manpower percentage}} {\text{class maximum manpower percentage}})^2 \cdot {\text{class recovery speed}}}$$


 * $${\text{class manpower percentage(t1)} = {\text{class manpower percentage (t1)} + {\text{class recovered manpower percentage (t1)}}}}$$
