As the 2007-09 Great Recession and its accompanying higher unemployment took its toll on U.S. families, food insecurity at the national level increased. In 2011, 14.9 percent of U.S. households were food insecure—up from 10.7 percent in 2001. Food-insecure households are those that were, at times, unable to provide adequate food for one or more household members due to insufficient money or other resources for food. States differed both in the percentage of households that were food insecure and in the change in that prevalence rate during the period. Changes in food security may signal worsening or improving economic conditions in a State or shifts in the composition of a State’s population.
