How many people are poor, and how fast are they leaving poverty? The World Bank (Chen and Ravallion 2001, 2010) says that a quarter of the people in the developing world lived on an income of less than $1.25 a day (the threshold of absolute poverty defined by the lowest poverty lines in developing countries), down from about 40% in 1992.

One of the first Millennium Development Goals is to reduce hunger by half between 1990 and 2015. To date, the global hunger count has fallen slightly, from 1 billion in 1990–1992 to 870 million in 2010–2012 (Food and Agriculture Organization 2013). As a proportion of the world’s population, this is just a one-third fall in the hunger rate, from 19% to 13%.
