Farms or Factories

How does population effect improvements

from GalCiv2 Forums
I know population increases taxpayers (and in turn revenue), give more people to send on colony ship and make excellent cannon fodder... I mean soilders for troop transports. But how do they figure in production and stuff like that.

What generates more money 10B people with 2 Markets, or 20B people with 1 Market (not neccessarily those numbers but you get the image). And more so, how does research on production play out (again, the x people to y factory/lab or 2x people 1/2y factory/lab example).

I ask because I had planets with only 5B people being Manufacture or Scientific paradises, while planets with 10s of Billions fairing worst than fledging colony. I have feeling while I am stabbing in the dark I loosing alot of efficiency in my colonial management.

Population does not affect production, only taxes. It does provide the bodies for colony ships, transports, and fighting off invasions, so leaving all your planets at 5B might not be a good idea.

A given population of X will generate Y tax income, and a population of 2X will generate 2Y. You then add up all your applicable econ bonuses, and that provides the final tax amount you will get from that colony. Econ bonuses come from economy technology, economy tile improvements, racial ability picks, and mining starbases on economy resources (the green one). Of these, the tile improvements will vary from colony to colony, the rest are fixed.

So, if a colony is bringing in 20BC a turn with no bonuses, a different colony with twice the population will bring in 40BC a turn, if it has no bonuses. Once bonuses are figured in, things get more complicated. Assume a "global" econ bonus of 20%, from techs or whatever. The two colonies now bring in 24BC and 48BC respectively. Advanced market centers add 10% to the econ bonus, so you'd think that adding 10 of them (100%) to the smaller colony would catch it up to the larger colony, but you'd be just a little bit wrong. The 100% adds to the 20%, so you're now adding a 120% bonus to a 20BC income, giving you a bonus of 24BC, for a total of 44BC, lagging 4BC behind the larger colony.

So in short market centers arent worth it unless you've got more than 10 farms down on that world?

If I've got 1 farm for 5b people, I can add either another farm (10b people, doubling income), or say an advanced market center (+10%).

Slight disparity there...

Market Centers eventually become stock markets, which also give morale bonuses.

That's not exactly how it works. Remember that a) it gets harder to manage population as it increases and b) you just can't increase population above a certain level dependant on the planet class.

don't forget you can research better farms to increase output from the original farm. More than 2 farms on a planets sounds like trouble to me.

Farms have morale requirements, which generally means locking up other tiles with morale buildings.

Stock markets provide morale, influence and economic bonuses. However, the economic bonus is less then the previous version on the tech tree and the other bonuses are far less then a building focused on that area. I don't upgrade it as I don't like the less efficient jack of all trade idea, but I can see where it would be useful on small planets that don’t have space for everything.

course you could turn around and spend that extra money in research/social/military which i believe increses your manufacturing.

Thanks for the responses, now I know what I am building on my colonies and why.
