"Contemporary historians ... right now, have failed to find a single historical example of a society that became secularised and maintained its birth rate over subsequent centuries," the former UK chief Rabbi, Jonathan Sacks, recently argued.
"Falling fertility has coincided so closely with massive secularization that we must at least ask whether the two phenomena are related, even if not in a neat one-to-one relationship", the scholar Philip Jenkins also said.
This is also true apparently for Germany.
