I wasn't going off my own assessment or gut feeling. I'm just pointing out what demographers trace the decline in birthrates to.
> affordable family housing doesn't exist in many places.
Yes, our standards have gone up with our wealth, but faster than our wealth. In the US, new houses are much larger than houses built in previous generations. Plus construction safety code (wiring, etc) have gone up. Plus we've allowed homeowners to restrict the building of density to protect their equity value. We could throw up shacks, but people want proper housing. But our view of what constitutes proper housing has gotten a lot more expensive. That goes with being in a wealthier society.
> If the next generation is much smaller, that will free up a lot of housing
Unless people continue to migrate. The cities have been gaining population, and the losses in population have been in rural areas. Even for moves between countries, it's usually the poorer rural areas where people are fleeing to find better economic opportunity. That there are empty houses in Appalachia, or somewhere in rural Guatemala, doesn't help people who are moving to Houston.
>Population change may look exponential, either up or down, but it really isn't.
Fertility rates do have a cumulatively exponential impact on population size. You are assuming they'll bounce back, but demographers have seen no indication of this. I'm not dropping my own intuitions on you, just deferring to what people who study this professionally have found. Some countries have increased from their nadir, but still stabilized at around 1.4-1.7, i.e. still below the replacement rate.
>There are a lot of constraints people respond to that affect population growth, like availability of resources, pathogens, and biological desires that we affect this.
A lot of things do go into birthrates. The things demographers have found most track with birthrate declines are here:
Poverty correlates with higher birthrates, not lower. Universal healthcare or lower income inequality also don't correlate with higher birthrates. Even the Scandinavian countries have low birthrates.
- Fertility rate: children per woman for countries with the lowest income inequality.
- Fertility rate: children per woman (for the countries with some version of universal healthcare)
- Fertility rate: children per woman (For Scandinavia, France, and a few other W. European countries)

If they sold those house to people of childbearing age, preferably earlier childbearing age, they would drastically increase the birth rate, but they don't. They only sell such house to people later in their careers who are out of, or at the very end of their child bearing years.
Of the people I know who have kids many of them are raising them in one-bedroom apartments the way our grandparents grew up. Talk about ways to ensure one and done.

This is highly effective way to suppress the birth rate. Don't create new living space, and people won't reproduce.
