The number of people worldwide living in extreme poverty—defined as living on $1.25 a day or less—was cut in half between 1990 and 2010. Yet more than one billion people still subsist at this level, and about three billion live at under $2.50 a day.Laurence Chandy, a fellow at the Brookings Institution, discusses the possibility that by 2030 the world might eradicate the most extreme poverty. He explains how we measure the problem, what the private sector and aid agencies can do about it, whether or not current targeting approaches are effective, and talks about the poverty problem in the United States.
