Eighty-nine percent of American households were food secure throughout the entire year 2001. The rest were food insecure at least some time during the year, meaning they did not always have access to enough food for active, healthy lives for all household members because they lacked sufficient money or other resources for food. The prevalence of food insecurity rose from 10.1 percent in 1999 to 10.7 percent in 2001, and the prevalence of food insecurity with hunger rose from 3.0 percent to 3.3 percent during the same period. This report, based on data from the December 2001 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 United States spent 32 percent more than the typical food-insecure household of the same size and household composition. About 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. About 19 percent of food-insecure households 2.8 percent of all U.S. households obtained emergency food from a food pantry at some time during the year.
