Small-Scale Question Sunday for April 2, 2023

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

I think @Stefferi had some stats about how the global fertility rate is below replacement because of the mortality rates in poorer countries, despite technically being above 2 per female.

I think it's basically on the edge, might dip below replacement this year or somewhere in the close future. I discussed this on Twitter a while ago and it seems the mortality rates are a bit lower than I though. The point is, though, that while generally replacement rate is considered to be 2,1, it's a bit higher than this globally, maybe like 2,2 or 2,3, and the global fertility rate is pretty close to this already.
