I think not.
Birth rate in humans is not related to fertility. Humans get hundreds or thousand chances to reproduce over their lifetime. Sperm counts number in the millions even if they are less viable. The chances that fertilisation happen and a successful pregnancy follows are super super high anywhere.
The way I see it: Richer people have better access to contraception, higher child survival rate, higher costs of education and have children at an older age. So they have fewer kids and fovus more resources per kid.
The trend is the same as poor countries turn into developed countries everywhere on earth.
The better predictor for number of kids per woman is whether the woman attended primary school. It shapes how she views family and contraception.
