Note:
(a) Fig 1 shows that an American with wealth in 5th percentile (first percentile is the poorest) increased his wealth by around minus 50%, whereas a Chinese in the 5th percentile increased his wealth by 200% in the same duration. In the same period, the richest American and Chinese (100th percentile -- that is, at the extreme right of this figure) increased his wealth by !230% and ~2,000%, respectively.
(b) Fig 3 shows: the left margin is "World's Poorest" (1 percentile) and the right margin is "World's Richest" (100 percentile). In 1990, China had ~40% of world' poorest, but in 2016 China had about half: ~20%.
(c) Regarding Fig 4 (now the same in both Chinese and English versions). The Chinese version says, "但从某些方面看，中国社会比美国更平等。以下是世界主要国家不平等和收入流动性的名次：&oq="但从某些方面看，中国社会比美国更平等。以下是世界主要国家不平等和收入流动性的名次:"
This introduction to Fig 4 does not appear in the English version (in other words, the English version does not have an introduction to Fig 4), which instead says, "But by some measures Chinese society has about the same level of inequality as the United States. Here are the world’s major countries ordered by inequality and income mobility."
At the end of the English version is a notice that does not appear in the Chinese version: "An earlier version of a chart on economic inequality used an older estimate of inequality in China. Based on the most recent World Bank data, economic inequality in China is roughly the same as in the United States, not slightly less."
(d) Fig 5 in English version has, on the x-axis: "Number of years since each country reached China’s per-capita GDP in 1993. In 2011 US dollars. Source: Maddison Project."
