Under 1 billion is unrealistic but some contraction will happen. The main factor dictating how many children people will have is infant mortality of the previous one or two generations as well as the existence of pension systems.
…which is the reason why developed countries have birth rates below replacement level and with increased wealth elsewhere it’s also going to happen there, which would mean contraction everywhere. I don’t expect that to keep up forever, however, states will get their shit together and set incentive structures (in particular making having kids affordable) long before we’re contracting to one billion.
Yes. The likely turning point, according to the UN, is around 11bn in 2100, then declining. Plus or minus a billion or two and a couple of decades.
Which is btw nowhere close to the earth’ carrying capacity though that’s highly variable in the first place. It’s probably not a good idea to pine for a population increase past that point and leave some room for other species. And no matter how many we are it’s a good idea to minimise ecological impact. Why do people want fresh strawberries in winter anyway those transportation-stable strains taste like water. If you want strawberries in winter eat jam.
Also note that this overshoot is happening precisely because developing countries are, well, developing: Their fertility rates still stick to the old child mortality rates but the actual rates are lower so you get a population spike. Keep that up a generation or two and they plateau, then fall as people don’t require kids to provide for them in old age and also are barely affording rent with dual income from three jobs each so they definitely can’t afford a kid. Oh wait that was the US in particular. But yes that’s exactly what you want to avoid to halt contraction.

Developing countries are not anywhere close to that happening. Their populations are still booming.

That’s great and all but it doesn’t help us with the much more immediate housing and climate crises.
