I couldn’t find a simple graph showing which countries are rich (high GDP per capita) and big (large population). I wanted to double check a claim by Noah Smith saying that Germany and the US were the only two large (more than 50M inhabitants) and very rich (more than $50k GDP per capita) countries. It’s indeed the case!
If we lower the GDP threshold to $40k, we can welcome the UK, France, South Korea, Italy and Japan to the big-and-rich quadrant. And there are 15 countries with more than 25M inhabitants and GDP per capita higher than $25,000.
