The World Bank used to think that 634 million Chinese were in extreme poverty in 1981 and 128 million in 2004. In a new paper that The Economist brings attention to, numbers are revised for the new PPP-data and the new numbers are 839 million and 287 million respectively, and a year later, in 2005, it was 204 million. We thought that 506 million Chinese had escaped poverty, but it seems like 635 million did.
