Worldwide, roughly 1 in 8 people suffered from chronic hunger from 2011 to 2013, according to a new report from three U.N. food agencies.
They concluded that 842 million people didn't get enough food to lead healthy lives in that period, a slight drop from the 868 million in the previous report.
The modest change was attributed to several factors, from economic growth in developing countries to investments in agriculture. And in some countries, people have benefited from money sent home by migrant workers. But the gains were unevenly distributed, the report's authors say.
