"Ability to buy a house or similar" and "affordable daycare" are probably enough to have a huge impact. We don't need a long list of possible answers.
- Reasonable maternity leave allowances.
- Good affordable (or free) healthcare.
- Good affordable (or free) child care until school age.
- Free education to university graduate level.
- Affordable housing.
The super-rich have no interest in allowing this to happen, so countries where having a child is a significant cost will continue to have low fertility rates.
I don't think you're necessarily wrong BTW but it's not that simple.
The two main hurdles to increasing birthrate are:
1. Convince couples with no kids to have one. 2. Convince couples with two/three kids to have one more.
The list might help but the question is how much for each.
Per this: https://en.wikipedia.org/wiki/List_of_sovereign_states_and_d...
* France, Denmark, Sweden, Ireland: 1.8
* Iceland, Czech Republic, UK, Latvia, Netherlands, Belgium, Lithuania, Norway: 1.7
* Romania, Slovenia, Estonia, Albania, Slovakia, Bulgaria, Germany, Switzerland, Austria: 1.6
Yes, there's some countries that have even lower levels (eg Italy and Greece), but that's a large chunk of Europe with a pretty similar fertility rate to the United States. I wouldn't give America a pass on any future sort of demographic discussion regarding this. Heck, China (which you list at "terminal") has a fertility rate of 1.7.
