About 10 percent of U.S. households were food insecure in 2021, meaning they had difficulty providing enough food for all their members at times because of a lack of resources. Though this number was relatively unchanged from the previous year, food insecurity for households with children declined to 12.5 percent from 14.8 in 2020. Households with no children accounted for two-thirds of food-insecure households, with single adults at the greatest risk. For rural areas, the prevalence is slightly lower than in urban areas, 10.8 percent versus 12.2 percent. The data is provided every year by the Economic Research Service at the U.S. Department of Agriculture.
