The Economist has a fun toy where you can compare Chinese provinces to various foreign countries. Some of the comparisons don’t help much, given that some of these places don’t mean a lot to me. Yunnan has the GDP per person of Vanuatu and Guangxi of Swaziland? O.K. On the other hand, Sichuan having the population of Germany is a helpful comparison.
The only thing I would have liked to see them add would be a comparison of income distributions. It’s nice to know how much wealth the people of Beijing would have if the money was all shared out equally, but of course it is not. Not sure if they have the data for that, though.
