Instead, the improvement in living conditions for almost 700 million people has been a step forward from the desperate existence of USD 2 or less a day into a low-income world of living on USD 2 to USD 10 daily, the Pew Research Center says.
Its report, released today, looks at changes in income for more than 110 countries between 2001 and 2011, the latest that data for such a large range of countries was available.
More than half of the world's middle-class population was living in the Asia and South Pacific region by 2011. That's a jump from 31 per cent to 51 per cent in a decade. Largely because of Asia, the report says the world's middle-income population nearly doubled over that time, from 399 million to 784 million.
The Pew report calls its overall findings "the uneven geography of the emerging middle class."
The poverty rate for India, Asia's other population giant, fell from 35 per cent to 20 per cent over the report's period, but its middle class only grew from 1 percent to 3 per cent.
The report notes that India's economic reforms began in 1991, 13 years after China, though the scope and pace of the countries' reforms have varied.
Also worth noting: Europe and North America's global share of the upper-middle income population fell from 76 per cent to 63 per cent by 2011 as the Asia-South Pacific region got richer.
Africa remained the poorest region, with 92 per cent of its population either poor or low-income by 2011, and in Cote d'Ivoire, Kenya, Madagascar and Zambia, "poverty actually increased significantly." South America almost reached the point where half of its population is at or above middle-income, at 47 per cent.
