Population growth: How exactly does it work?

[dogscoff]

OK, so I'm trying to take all the scraps of information piled together on the 'population' wiki page ( http://wiki.spaceempires.net/index.p...ion_%28SEIV%29 ) and turn it into a nice, easy-to read, pretty-to-look-at, fully marked up wiki page. However I want to get the facts right, and something isn't clear:

There is a table on the wiki with happiness on one axis and plantary conditions on the other. It isn't clear, though, how the numbers in that table are applied to the "population growth" figue. For example, if the table yields 13 for my particular combination of happiness/ conditions, and I have a +2 racial population growth modifier, and then a further +1 from taking environmental resistance up to 105%, would my pop growth rate for that planet be

10% base rate +2% modifier + 1% modifier +13% happiness/condition modifier = 26%? Or would it be
something else entirely?

Anyone any wiser than me?

All of the factors combine linearly to get the final growth rate.

[dogscoff]

So what does that mean? That my example (26%) in the original post is correct?

[Fyron]

They add together. Your example is correct.

[dogscoff]

Cool, thanks. I'll go wiki it.

It's a bit scrappy, but it's an improvement on what was there before. Feel free to tidy it up, people.

[Q]

Has increased environmental resistance an effect if the planet condition is optimal?? If so that would be a little odd in my opinion.
And if the planet condition is deadly does increased environmental resistance rise the population growth over zero or has it no effect?

[Fyron]

ER has no relation to planetary conditions; it is just a 1/5th reproduction and happiness effect.

Optimal planets get the same benefit/penalty from ER as any other.

Deadly planets can have positive growth rates either from high levels of ER or from high levels of reproduction (or a combination). In a quick test, 130% reproduction and 100% ER netted 22% growth rate on a deadly planet. Deadly just means the base rate is very low, some negative value.

How does that "Reproduction Check Frequency" factor in?

[Fyron]

Population is increased by 1/10th of the reproduction rate every X turns, where X is that frequency. Thus, in stock, you sort of get the reproduction rate being growth in a year. It is yearly growth, compounded monthly.

If you set Repr. Freq. to 2, it means no pop will grow after one turn, and you will get 1/10th repro rate growth on the second turn. Set it to 3, you get the 1/10th growth every 3 turns, and so on.
