IIRC advances in women's education and healthcare have historically correlated with sharp declines in birth rates in developing countries.

Tried and true birth rate reduction method

Women do not need a bachelor’s degree to learn how to not get pregnant.

The whole society needs to accept that women should have rights to birth control, and should have control of when and who they have sex with. And, of course, educated women become able to sell services/goods that allow them to be financially independent, so as to not be coercible.

This happens to correlate with a society where women are more educated, but due to differences in physical power, “educated” men have to be part of the equation.

With no evidence to offer I strongly suspect this is the biggest piece of it

>And, of course, educated women become able to sell services/goods that allow them to be financially independent, so as to not be coercible.

I do not see a reason to rank the causal factors, but I can point to a few societies where the women and men are “educated”, but the women lack the rights they have elsewhere (either legally or practically).

> Women do not need a bachelor’s degree to learn how to not get pregnant.

That is because educated women might choose to pursue a career or have fewer kids, not because birth control is hard to understand.

Besides, empower women to do what they want with their life instead of being walking incubators.

This must be the most superficial comment I have ever read on HN.

Have there been any societies in the past where women were allowed an education but men were not, because the reverse was common.

Probably not, but there are countries where women are allowed an education and still do not have the rights they should have. Which is alluded to by the fact that they are “allowed” an education in the first place.
