The "fertility crash" is only impacting the developed world.

As the article directly states, global population projections are set to grow by another 3 billion. I would call that a fertility explosion, not a crash, but most of that population growth will be happening in the undeveloped and developing world rather than the developed world.

think calculus for this one, growth continuing in the positive will mislead when that growth is losing steam. Watch the animation near x=1 https://en.wikipedia.org/wiki/Second_derivative#Relation_to_.... The slope must decrease and reach flatline before it goes negative. It's all a matter of rates not absolute figures. Like a ball thrown up in the air, it goes up, and eventually reaches its peak, then begins its descent. We're nearing the peak population wise which is what a lot of these articles are getting at.
