Instead, the “experts” are now saying the global population will likely peak and then begin to decline around the middle of this century, and that some countries. Some countries, like Italy, Japan, and China, will lose half their population or more by 2100, while the population of sub-Saharan Africa will triple. Populations in the developed world will have aged dramatically, and countries will be competing for immigrants to replace their vanishing workforce.
They’re probably wrong about most of this as well.
One reason the “experts” always get it wrong is that people change and adapt.
Countries that are rapidly losing population could easily create policies that rewarded families with children and punished single unmarried folks, for example.
