experts: overpopulation morale effects, are there #s?

An easier method is to just look at the planet menu and look at the morale number. If you drop below 52% your population will start to decrease.

Simple, no?

And don't forget... you can sort (order) by morale. Default is class a.k.a. PQ

i dont think you ever need to dump population. Just build the moral boosting buildings on your worlds, along with the PQ bonuses. Sure the moral might dip to 60 or so once in a while, but once it finishes the next Teleporter/Entertainment Network/Stadium/Multimedia center, its back up to 100%. Once you build all of the moral boosters that you can save Virtual Reality/News Network/Medical Center, you should be permantly at 100% moral, even on starting 14 PQ planets, even without a moral galactic resource. If your on a smaller map size, a good way to keep the moral up is keep taxes very low (like 20%) and base your income solely on trade (a minor civ in a corner gaurded by you works good, or a weak major).

Black Shade...

Pop size is limited by PQ is is not? So... depending on how long the games goes...

It is posible to hit the pop limit and then morale starts to drop. As morale drops so does income. Even if you are trading.

It that case I use transport/combat transport to off load the excess pop... And of course use them as troops.

Amazing how many different ways there are to achive the same ends with this game.

I always find with morale resources, terraforming and so on that I can keep up with my population growth in the late game - maybe this would be less true if I wanted to hang around and research Final Frontier.
The only time I find population a major problem is when I've culture-flipped an alien world, and he's stripped it of all improvements to annoy me. In that case, I have to build a colony ship and take away almost all of the population, usually transporting them to a high PQ world.

I think that population limit is 100B regardless of PQ. I have played several games that went on long enough for all planets to max out on population at 100B each. There may be other lower limits imposed because of the lack of population sustaining buildings, but I had built everything on the planets, so at least under those conditions, I think that 100B is the limit.

See the "morale tips" sticky thread at the top of this forum.

yeah, the moral tips thing is very helpful, but ive found that ive never had moral trouble late game even on PQ 13/14 worlds. They never drop below 100% once i reach a certain point in the game (around teleporters/stadiums for me).

Interesting. I always have morale problems, sometimes dropping down to around 50% before I get into a true social phase of building. And I build everything, and morale always drops off again. Destabilization?

There is a pop limit of 100B no matter what the PQ. However the limit can only be reached once you have sufficent PQ improvements, social improvement, techs and morale resources.

As mention by Black Shade and Matt, mid to late game is when you probably have sufficent modifiers to achive 100B.

Until then you can always get an over population problem on a world. And taking them off increses your tax revenue. Take off the pop then click on the planet in the planet list. You'll see the change in revenue happen immediately. As mentioned by others in this forum, taxes of course are limited to 4xPQ on any world.

This I did not know. I thought it just effected elections and population growth. I read the whole morale thread and never pick up on this fact. What is the relationship between morale and tax revenue. Less people paying tax can actually increases revenue? :notsure:

No, as your morale increases (by removing people, for example), more people will start paying taxes (being reported) and show as population growth.

When you have a planet with enough PQ and morale boosters to handle the extra population, you can dump them back on the planet. Population in ships do not pay taxes.

Convoluted? Yes.

If you want to see the drastic effect of morale on taxes, try move the taxes sliders until your planet reach 25% morale. There is a huge drop in taxes at this point. It is also the point where the little red icon appers next to the planet.

I think there's more to it than that, as Phoenix says. It's not just population growth, it's an immediate effect that occurs at certain morale levels - I'm not sure which.
And there's a further point that hasn't been mentioned. Say you take off half the population from all your planets. Morale will go up immediately, and you can then afford to raise tax levels without it risking growth or elections or rebellions. This can mean more money from less people.
(But don't take my word for it - I never do this.)

Here is a post I have made on population growth in the public forum on the Senate Halls. The post can be found here http://diplomats.galciv.org/forum/viewtopic.php?t=385

Here are some informations about the population growth calculation.
The population growth of a planet if 3% if morale is more than 54%. If the morale is equal to 100%, the population growth is doubled. The empire growth bonus is applied on the base growth. And everything is capped at 200 Millions.

An example will be cleared, with a 2000 Millions planet and 50% empire wide pop growth bonus:
morale >= 54% --> base growth = 2000*0.03 = 60 population
50% pop growth bonus --> growth = 60 + 60*0.5 = 60*(1.5) = 90.
So if morale is between 54% and 99% we have next month 2090 million people on the planet.
But if morale is 100%, we have 2180 millions population next month.

The minimum population on a planet giving the cap limitation with 3% base growth is given by the formula:
Pop = 200/(0.03*(1+growth bonus/100). And this give the following table:
0 6667
10 6061
20 5556
30 5128
40 4762
50 4444
60 4167
70 3922
80 3704
90 3509
100 3333
110 3175
120 3030
130 2899
140 2778
150 2667

Which means that if you have the aphrodisiac (50% growth bonus) and basic enviromment tech (10% growth bonus and habitat imporvement), as soon as the planet reach with 4167 millions persons, you no longer have to worry about having a 100% morale on this planet for a maximal growth. Having 54% is sufficient. Which is great for taxes.
