Declining workforce

Lately I've been struggling with declining workforce. I've bought like 5 million people to my country to tackle this problem, yet it has been only a temporary solution as my population growth has come down from +20k to +8k per month. For instance, in the last 9 months my workforce has declined by 130k which means that if it goes on like this, I'll soon have to start shutting down companies.

Is this normal and is there anything I could do? I was thinking maybe I should try to lower the welfare index of my country, because in real world better life usually results lower birth rates.

...Or is it just that 90% social security payment is a bit too high. I'll lower it to 80%, let's see if it helps.

Nope, that wont help. Higher SS will increase welfare which will increase your migration index. A small addition to your pop growth.

You are probably seeing the lessening of free population gifts as your account becomes older. Also, quite important, is to get your health index to over 100. Keeping an eye on the birth and death rates, birth particularly, and increases in pop aged between 18 and 35. These are your baby makers.

How exactly do you increase a specific age group isn't that totally under the control of the game?

also how do you have 100% employment?

it seems that i always have unemployment regardless of how many corporations i built.

For Xiong, Overbuild corporations. Not all have to be at 100% hiring. That will also help when you hit down markets - you can shut down hiring in one corp, increase it in another.

For cassieconners,
Not sure exactly what you're asking. The factors that affect age are primarily in the game's control. You can mitigate with pop transfers (trade those getting ready to retire) - I'd recommend doing that with a computer controlled country, not a player. (to keep a bridge open if you need to do it again in the future). Or trade in baby boomers for the golden agers - but wouldn't recommend that either, unless you are doing index research, or helping a friend/Fed mate out of a retirement bubble.

Your health care system will also affect the absolute numbers of each age group - by keeping them alive.
