Almost all - 98% - live in developing countries. Asia remains the continent most affected, but Africa is the only place where hunger is increasing, around 20 million in the last four years alone.
Despite this worrying trend, the UN Food and Agriculture Organization - FAO - is optimistic because compared to the 90s, there are 132 million fewer people who are going hungry. If the average annual reduction in numbers continues, one of the Millennium Development Goals could be achieved.
The Millennium Development Goals consist of eight objectives on human development that the 189 UN member nations agreed to arrive at by 2015. Among those proposed is reducing by half the number of malnourished people.
