Eighty-nine percent of American households were food secure throughout the entire year in 2003, meaning that they had access, at all times, to enough food for an active, healthy life for all household members. The remaining households were food insecure at least some time during that year. The prevalence of food insecurity, 11.2 percent of households, was not statistically different from the 11.1 percent observed in 2002. The prevalence of food insecurity with hunger was unchanged at 3.5 percent. This report, based on data from the December 2003 food security survey, provides the most recent statistics on the food security of U.S. households, as well as on how much they spent for food and the extent to which food-insecure households participated in Federal and community food assistance programs. Survey responses indicate that the typical food-secure household in the U.S. spent 34 percent more on food than the typical food-insecure household of the same size and household composition. Just over one-half of all food-insecure households participated in one or more of the three largest Federal food assistance programs during the month prior to the survey.
