As you all know humans as they develop tend to have less kids. What you might not know is that this has happened before. The case being that many societies once they reached their peak saw a phase where they all saw a decrease in their fertility rate. (Someone correct me if I am wrong)
My personal theory is that human civilization by design tends to encourage the spread of IQ rather than maxing it out at the top for multiple generations so those at the top naturally die out to rebalance the average IQ while uplifting it. Like hyperspecialized ant workers.
So taking that into account I think the US will decay in the 2100's followed by China in the 2200's and India peaking then.
The ideal population I believe would stabilize around 4 billion people globally after all predators and animals larger than humans have been eliminated and only humans with a desire to reproduce remain.
What do you all think would be the stable global population?

Because China is definitely capable of ordering its citizens to reproduce.
