The level of hunger in developing countries as a group has fallen by 27 percent since 2000. While the world has made progress in reducing hunger in recent decades, the state of hunger is still serious or alarming in 52 countries. These findings come from the 2015 Global Hunger Index (GHI) report, the tenth in an annual series that tracks the state of hunger worldwide, regionally, and by country, turning a spotlight on those regions and countries where action is needed most to address hunger. This report's GHI scores are based on a new, improved formula that reflects the multidimensional nature of hunger by combining four indicators related to undernourishment, wasting, stunting, and child mortality.
