In the village where I was raised, all families had kids until the wife cannot have them anymore or dies because of that. And because of the rapid decline of religion over there, it was pretty much inbreeding as there are not many candidates that want a life like that outside these families, so always some of them have massive defects (my neighbour had a son born without a left arm, a blind daughter, a son with a disabling low iq, and more like that).
