This Table had a profound influence on my thinking - a case of scales dropping from eyes...
Of course, since the book was written 18 years ago, the precise estimates for 2025 have changed - but the direction, speed and severity of changes in the size and composition of the world population over the past century are stunning - and presumably unprecedented in world history.
But, naturally, nobody talks about this stuff.
