What do you do when the industrial production outgrowth the population? I started outsourcing research to Luna and Mars, while the fuel refineries and ammo factories are on Venus. I might send the fighter factories there as well. The banks are placed on the Jovian moons while mines are wherever they are useful. The problem is that I am still lacking wage slaves.
There are no idle shipyard either that could free more people.
It looks like you are being crippled by the lack of population growth. If colonies grow exponentially at the beginning, they tend to stabilize to a few % later. Also one day you may hit the planetary cap, which means there isn't much more you can do.
My advice? It's time to find a "new" Earth and expand there. It will take time but, if you are still playing Aurora, that should be a commodity you sure aren't lacking.
Maybe putting 25% of my ground construction capabilities into construction factories is not sustainable anymore. I switched away from making mines to automated mines so that the colonies can supply resources and wealth.
Yup - With a standard start, pop seems to always be one of the 2-3 tight resources for me in early game. You can easily overbuild Const Factories and start the domino effect. It can be a problem with overbuilding (per your pop level) any Installations that requires workers, but for me Const Factories are usually the trigger. More Factories = more workers needed and your other installations are getting built faster, unless you keep a close eye. Which will need even more workers. Moving Installations as you are is a big help.
What I do:
1) Colony creation for eventual pop growth. It's a 'first steps' priority for me to get the three, 2CC colonies up asap. I sacrifice some early Installation builds to make sure I have spare pop for colonies.
2) Watch your spare pop levels. If I ever drop below 10M spare workers on Earth, I assume trouble is coming and start taking steps. If I get to -workers, I waited too long.
3) Mostly I juggle the Industry Orders to keep installation construction throttled when it becomes an issue.
4) Research and Financial are the easiest to move off Earth. I try to move anything that doesn't require micro first. Shipyards, Refineries etc use minerals and will require an additional supply chain if not on Earth.
5) Avoid overbuilding shipyards early. Having a 25k ton military shipyard with 5 slipways is awesome, until you don't need any ships for a year. Those workers are used up but idle. IceRangers Bridging Function has saved me millions of workers by helping me learn and utilize 'sister' classes of ships. Being able to pump out all 6-8 of my DD designs from a single yard saves a few pop.
