Recent trends in high-income fertility

Today's issue of Nature includes an article showing a reversal in trend fertility for high-development countries around something like 1990. A Times commentary is here. And my advisor/collaborator Shripad Tuljapurkar has a commentary piece in the same issue of Nature.

The latter points out that the effect on the world total fertility rate is circumscribed. One of the concerns is whether human population growth may not be in fact heading toward a stable 9 billion. "Stable" and "9 billion" sound like conflicting concepts, don't they!
