Are you saying the process that creates risk is ending or that we are simply hitting a boundary condition (i.e. The edge of the Petri dish)?

TFR is synthetic based on population behavior (I.e. Not solely intrinsic, such as genetic).

My point is that there is a feedback-loop at work here. Educated women self-select against reproduction because the consequences are more obvious. But under-educated women still have high TFR-- they will need to hit hard boundaries (starvation, dieback).

I don't think the process of overpopulation is ending, just clamped.
