The estimated percentage of U.S. households that were food insecure in 2015 declined significantly from 2014, to 12.7 percent, continuing a downward trend in food insecurity from a high of 14.9 percent in 2011. The 2015 prevalence of food insecurity was still above the 2007 prerecessionary level of 11.1 percent. In 2015, the percentage of households with food insecurity in the severe range—very low food security—also declined significantly. • In 2015, 87.3 percent of U.S. households were food secure throughout the year. The remaining 12.7 percent (15.8 million households) were food insecure. Food-insecure households (those with low and very low food security) had difficulty at some time during the year providing enough food for all their members due to a lack of resources. The decline from 2014 (14.0 percent) was statistically significant. • In 2015, 5.0 percent of U.S. households (6.3 million households) had very low food security, down from 5.6 percent in 2014. In this more severe range of food insecurity, the food intake of some household members was reduced and normal eating patterns were disrupted at times during the year due to limited resources. This decline was also statistically significant. • Children were food insecure at times during the year in 7.8 percent of U.S. households with children (3.0 million households), down significantly from 9.4 percent in 2014. These households were unable at times during the year to provide adequate, nutritious food for their children.
