Population growth in v1.11

Clearly the manual is now wholly wrong about population growth. So, with version 1.11, how does population growth actually get calculated?

Is it exponential? Does surplus food affect it? Does approval affect it?

I was curious about that as well since moving people between colonies in order to maximize population and therefore taxes is dependant on how this works.

Approval does affect it, but food does not. 100% approval gives you a doubling of population growth.

The primary factor is the number of people on-planet.

Hi!

Check wiki https://www.galciv.wikia.com/wiki/Population , there it's explained in whole, with all numbers.

So I go to wiki and still don't have all the information I need for population. From wiki:

Maximum Population (in billions) = 0.02 * ( ( PQ + 1 ) ^ 3 ) w/ PQ = Planet Quality

PQ = 8 -> Max Pop = 14.58 B

OK, thats not a problem. Unless you move people to the colony, this is the max population.


Population Growth = CurrentMorale X Government Level X PlanetQuality Factor X GrowthFactor.

Current Morale in what units? (% ?)
Government Level (Where do you get this?)
Planet Quality Fact (Obvious)
Growth Factor (again, where do you get this?)


if(lPopulationChange > 100)

lPopulationChange = 100;
if(lMorale >75)

lPopulationChange *=1.25;
if(lMorale == 100)

lPopulationChange *=2;
fPopulationBonus = 1.0 + ((float) pCiv->GetAbility(ABILITY_POPULATIONGROWTH)/ 100.0f);

lPopulationChange = lPopulationChange * fPopulationBonus;

OK, what is the initial value of lPopulationChange? (Is this from Population Growth from above?)

I understand the code but ABILITY_POPULATIONGROWTH - is this the inherent population growth of the species in question?

Those formulas could easily be outdated. You better check the small section "Game version 1.1" below "Initial Population Growth//Illustrative Numbers" title.

I saw that but I thought the point here was how does the population formula work, not what are the approximate increases based on morale. I want to know how it works to see if my strategy needs changing.
