>> I'd say that the human desire for reproduction might work in the same way, only instead of prey, maybe real-estate prices and quality of life is the cyclical variable to note.

>This is likely true on the extremes to some degree, but I haven’t seen much evidence that this is a driving force of population dynamics.

In South Korea, young people are struggling to find affordable places to live, to the extent that many people live with their parents well into their 30ies. Coincidently, they also have one of the lowest birth rates in the world.

In my city, I see a lot of people who first build a house or buy an appartement, and then have kids, in their 30ies, because they can't afford a big enough place before that.

As housing prices rise everywhere, it takes longer and longer for people to be able to afford a place big enough for a family. Of course people then delay having kids, and many end up not having kids at all.
