1/OK, data mystery time.
This New York Times feature shows China with a Gini Index of less than 30, which would make it more equal than Canada, France, or the Netherlands. https://t.co/g3Sv6DZTDE
That's weird. Income inequality in China is legendary.
Let's check this number.
The report is available here: https://t.co/mrvWz1IzIe
The graph cites the World Development Indicators as its source for the income inequality data.

Here's the Gini index: https://t.co/MvylQzpX6A
It looks as if the latest estimate for China's Gini is 42.2.
That estimate is from 2012.
I can't find the <30 number anywhere. The only other estimate in the tables for China is from 2008, when it was estimated at 42.8.
Everyone except the "Fair Progress?" report, and the New York Times feature, seems to agree that the World Bank's most recent estimate of China's Gini is 42.2.

But the GDIM doesn't have income GINIs. So that can't be where these weird numbers were from (unless the data was mislabeled).

Wow. China has higher income mobility and lower inequality than the United States https://t.co/29BHdzbAll

The Gini number the NYT used was from the 1980s. It was not labeled as such.
Hi Noah, Thanks for reaching out. The figure you refer to shows a Great Gatsby curve that plots income mobility against inequality for parents generation, i.e. inequality in 80s. Gini for China is around 0.3 at that time, and can be found in PovCalNet & @BrankoMilan All the Ginis
