How many people are poor, and how fast are they leaving poverty? The data, if it exists at all, can be conflicting. The World Bank estimates that 25 percent of the people in the developing world live on an income of less than $1.25 a day (that's the threshold of absolute poverty defined by the lowest poverty lines in developing countries), down from about 40 percent in 1992. However, some other economists argue that absolute poverty is much lower (under 5 percent in 2010), and has declined much faster.
