While I don’t disagree that houses have become less affordable, that graph is rather misleading. A graph of the ratio, as posted in one of the comments [0], would be more informative.
Israel has arguably the worst income to house price ratio in the OECD at 160 monthly wages (~13 annual salaries) which is more than twice the US at 68 but they have also the highest TFR in the developed world even when you exclude the Orthodox Jews…
So it’s not as simple as housing is not affordable… it does feel like it’s very much cultural/social I can more than afford to have children but I’m at almost 40 and I don’t. And speaking from the pool of a rented villa in Greece I got on whim for 2 weeks because I got annoyed at work I can’t even begin to think about having them…
