Why do you think that this is true? Look at the countries by hours worked: https://en.wikipedia.org/wiki/List_of_countries_by_average_a... and there is basically no correlation between birth rates and hours worked. Countries with higher hours worked actually have higher birth rates!

[South Korea has a high birth rate for religious groups than non-religious](https://www.demographic-research.org/volumes/vol44/23/44-23....) no religion, 1.13; Buddhist, 1.33; Catholic, 1.16; Protestant, 1.28; and “other religion,” 1.20. This is the same country with the same problems for all groups.

That’s not it at all. The uncomfortable reality is if women work professional jobs you will have a low birth rate. That’s entirely what the data points at. Having kids is almost entirely cultural.

Had this assertion been true India wouldn't have been the most populous country on earth.

Average hours worked in Japan are comparable to the UK and significantly lower than the US, Canada, Czechia, and Israel [0], yet they all have significantly higher birth rates than Japan.

The issue in Japan and Asia in general is cultural. Women are still expected to both hold a career and do all household chores and have 2 kids. In a lot of cases, jobs will de facto fire women if they have kids because of the cultural expectation that they will leave to have kids and become a housewife.

Unsurprisingly, plenty of Japanese women have decided they don't want that life and have decided against marriage. On the other side of the coin, plenty of Japanese women hold off on marriage until they find a partner who can afford to be a primary earner. Unsurprisingly, this means higher educated households in Japan tend to have a higher birth rate than less educated ones [1] as they tend to be more economically stable.

The only developed country which has an above replacement TFR is Israel (even non-religious secular Israelis have a replacement TFR), and it's culturally one of the most pro-children societies I've ever been and much more gender egalitarian than other countries.

All conversations about TFR and birth rates on HN are from a male point of view and never actually as why women don't want kids or maybe don't want to date a number of HNers/Redditors. It's very incel-like in nature.

Except there is the awkward fact that it is the third world which has higher population growth rates and the nordics have are leaders in low birth rates.
