You don't mention the outlier - Israel stands out in the OECD fertility rate race - 2.89 in 2023 (if I'm reading https://www.oecd.org/en/data/indicators/fertility-rates.html correctly) while the next highest is France at 1.91.

A click-bait article I read mentioned that Israel's culture is more child-rearing friendly than others, like the United States, where kid-friendly gathering places are not encouraged.

the article at https://www.taubcenter.org.il/en/research/why-are-there-so-m... mentions several possible reasons for the increased fertility, at least compared to OECD countries - Israel's birth rate is similar to its neighbours, Egypt and Syria, according to the article.
