Nice map, very clear.

For anyone wondering, one of the biggest reasons for changing fertility is the education of women. There's a provable trend that better educated women have fewer babies.

Globally observed data is that: Women with little or no formal education tend to have more children. Women with secondary education have fewer. Women with university level education have the fewest children on average. So if you compared this map with one of women's education, I suspect there'd be a fairly close match.

That education also comes at a general trend of improved living standards for the whole population, so improving countries have an overall lessening fertility and the improved education is a product of that.

(I'm not an expert by any means - I'm just someone who fell down a rabbithole some time ago and spent an evening trying to understand this correlation. )

This on a non-issue. The baby crisis has more to do with capitalists making everything unaffordable and therefore making family planning mostly impossible in most modern countries.

Why is replacement ratio for a stable population size 2.1 and not 2

Cause some people die before having kids or are infertile

Would be nice to have emigration/immigration data in the side.

The migration map would be more useful if it showed "flows" -- i.e. inflow to country vs outflow, then cross-correlated against birth-rates over time. Also, whether the migrants are temporary workers vs. permanent residents and citizens. Temporary workers usually don't set down roots and assimilate.

That way you could see which countries are heading toward population collapse.

Just looked at the linked migrants post and USA and Germany are in the top, but still has quite low birth rates.

[–] claimsou@lemmy.world 3 points 2 weeks ago

Yes. This is where China is very different. Not only low birth rates but also people leaving/low immigration.
