Lights, camera ... income!: Estimating poverty using national accounts, survey means, and lights

Maxim Pinkovskiy, Xavier Sala-i-Martin, 27 February 2014



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.

More to do on measuring hunger

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%.
