While all three are good policies to have, they aren't enough to make people want to have babies as demonstrated by birth rates in most countries that have them. It turns out that raising a human properly is a lot of work and a lot of responsibility, not to say that it requires women to go through pregnancy and childbirth, both exhausting and potentially traumatic events. If we are to raise birth rates, we need to offer way more than just this bare minimum.

Changing our societal structure to encourage communal child raising so that responsibility doesn't fall fully on young inexperienced parents would be one potential step. Developing tools to help women go through pregnancy and childbirth more easily would be another.

All three are offered in every developed nation, where do you live?
