Fertility rates are declining rapidly across the entire world, especially so in most developed countries.
If you take e.g. Germany or Hungary, the level of support they provide to families with children, silly low cost of childcare, taxation exemption, the list goes on, still their fertility rates are about 1.58.
Even in Africa it's declined from 4.7 to 4.1 in the same 12 years which is 13%.
Probably not a bad thing given planet's resources
