Base Production

Assuming no buildings that affect production are in a province and ignoring production debuffs due to occupied/annexed statuses, its production is calculated by two fomulae.

If $\text{population}<5$:

$\text{floor}(\text{baseProduction}\times (\text{morale}\times 0.8+0.25)\times \text{resourceProductionFactor}\times (\text{population}\times 0.2))$

else if $\text{population}>5$:

$\text{floor}(\text{baseProduction}\times (\text{morale}\times 0.8+0.25)\times \text{resourceProductionFactor}\times (\text{population}\times 0.05+0.75))$

resourceProductionFactor is given in the table below:

resourceProductionFactor

Money	0.375
Rare Materials	0.3
Electronics	0.375
Components	0.45
Fuel	0.525
Supplies	0.525

Note that Manpower is not calculated using this formula and is instead given fixed values based solely on population. Also note that the level 1 Air Base that spawns by default in the HQ contributes a +5% production bonus.
