We still won't reach peak population until 2060 at the earliest, and more likely around 2100. [1] has a good graph by region on page 4, and a graph for world population near the end. Most regions haven't reached their population peak yet and subsaharan Africa is still growing strongly.

Of course a lot of this is just delayed by higher life expectancies. Aging populations will require major social reforms in our lifetime, and I don't think society is really prepared
