The graph above comes from an updated version of Shorrocks, Davies and Lluberas’s “Global Wealth Report 2012.” The presentation is available here. The rich, the top decile, are basically in Europe, US and Canada, and Japan (that is the relevant Asia-Pacific at the high end), while the poor are in Africa, India and Asia-Pacific excluding China, India, and Japan. China essentially dominates the middle deciles.

PS: I had commented on the original report here.
