The Demographic Transition and the Relationship Between Income and Fertility

The first demographic transition I think we can agree is quite straightforwardly material in terms of its causation. Education, urbanization and rising incomes are the three kind that's the trinity which drives down fertility rate. The second demographics transition seems to be much more fuzzy and cultural. religion for instance is an enormous predictor of fertility in otherwise low fertility countries. It gives us a little bit of hope every group has a more educated they are the lower their fertility rate until you compare master students to PhDs.
