Google “elephant graph” or go to ourworldindata and you should find it. Population growth has been dominated by income increases. The average person in China in particular got much richer.
Interesting that 0% growth at the 80th percentile and minimal growth at 90% is exactly the stagnation I was expecting.
Though, sub 50% growth from 1980-2016 for the 60th to 95th percentile is more interesting. With the top 1% capturing 26% of all growth and the top 0.01% having 200+% growth. It’s clear arbitrary starting and end points can shift these graphs around dramatically. Ending now is probably going to make a graph like this look really bad.
