This isn’t even correct, the highest birth rate in the world is currently 7 in Niger. The birth rate is intact falling massively everywhere.
Considering some of those die, it’s hardly an immense number, in fact if the level of inhospitable areas on the planet rise, then the birth rate will also likely rise to counter.
I thought it was considerably more.
But either way, you can see the top 30 in the list are all third-world countries, so my point still stands, poorer countries are still breeding significantly more than developed countries.
