You started with fertility rate and switched to birth rate. The world fertility rate is 2.4 so just a bit above the maintenance 2.1 level.

But in pretty much all developed countries the fertility rate is well below replacement rates and no signs of it levelling off.

In developed countries, more and more the norm is to not have children, or fewer of them later and later in live.

Personally I don't think it's a good thing when we start closing schools cause there's not enough children to attend them but that's just me.
