Current TFR in China is around 1.7 according to https://www.statista.com/statistics/1033738/fertility-rate-c... it _has_ been climbing very slowly recently, but I'm not sure I would characterize that as "healthy".

"Asia" is pretty broad, but India was at 2.2 in 2020 and dropping pretty rapidly; as of earlier this spring it hit 2.0. Note that the Statista numbers are moving 5-year averages, so the "spot" number for India is lower than the number you see on that graph.

https://www.statista.com/statistics/1034075/fertility-rate-w... puts "Asia" as a whole at 2.15, which is indeed "healthy", but the slope is very much down.

Africa does have higher fertility, but from what I can tell the main reason is lack of access to birth control, not "community" or "big homes"...

China had a literal one child policy to combat exponential growth in population. India incentivised small families.

Population grows exponentially and it is also a function of time. I don’t think we should look at it in decades but rather as through lenses that capture time in centuries.

The operative word being "had". It hasn't had one in a while.

> Population grows exponentially

It really depends. It does if you assume TFR is a constant, but it tends to not be constant.

In the "centuries" timeframe, technological change (much reduced infant mortality, availability of contraception, career opportunities, etc) pretty much dominates the TFR situation.
