We were recently contacted by someone who has come across the well publicized figure of 1 billion people in a state of food insecurity. This researcher wanted to know if we could provide statistics on the figure from 2000.
I found the answer here, on FAO's hunger portal. This portal provides the current year's figure with historical figures back to 1971. It also displays FAO's interactive hunger map and a list of related links like the Millenium Development Goals.
