Peak population will be a huge paradigm shift for the world economy. For the entire history of the world we have relied on growth, and the main deiver of economic growth has been population growth. No more!

Peak population isn't coming in the next few centuries. The 2008 UN data these charts are based on had mistaken data on African growth. African fertility is much higher than expected then and continues not to fall. The later 2100s in these charts now look to add several more billion and growing, almost all in Africa. Or from Africa; migration from poorer and overcrowded countries means Europe will probably be majorit…

I really don't think earth is going to be able to support 9 billion people without some sort of dramatic paradigm shift in the way, as a species, we consume things

If somebody does not have imagination about what will happen then I would recommend to study the art of wine making. It has some quite valuable lessons to teach.

Just a note, in the first figure, the annual population growth rate is shown as the percentage of the population size at that time, not as absolute growth rate in number or humans added. Neither is more correct than other, but they are different ways to present things.

Sourdough breadmaking and all the culture you have to constantly throw away to keep it from metastasizing or getting infected is very informative also.

We're well on our way to 15+ billion without pause on the current UN projections, so hang on for a scary ride.

All I can say is, if you want to maintain that standard of living in western democracies, you'd better get used to immigration.

Just curious if anyone has recent examples where a region's standard of living has shifted to trend downward for any reason?

You are expected to live 40.1 years as a citizen of India Well that is depressing.

Not really. You're expected to die in childhood. Survive that, you'll likely live about as long as anybody anywhere else.

Close, but not quite. Ie at age 30, the site gives me 53.4 more years in Germany, and 42.1 in India.

If there are heritable traits that lead to people having more kids in a developed world environment then at some point evolution will take over and we'll start to see exponential growth again.

This assumes that biological evolution is the only systematic effect on population growth rate. I would argue that the fact that we have decreased infant mortality at the same time as decreased population growth is evidence that there are other systematic pressures limiting population growth.
