ERS plays a leading role in Federal research on food security—access by all people at all times to enough food for an active, healthy life—in U.S. households and communities; its impact on the well-being of children, adults, families, and communities; and its relationship to public policies, public assistance programs, and the economy.
In 2010, 85.5 percent of U.S. households were food
secure throughout the entire year, and 14.5 percent
of households were food insecure at least some time
during that year. The difference in the percentage of food insecure households from the 2009 estimate (14.7 percent) was not statistically significant.
In 2010, 5.4 percent of households experienced food insecurity in the more severe range, described as very low food security, down from 5.7 percent in 2009.
ERS provides data access and technical support to social science scholars to facilitate their research on food security and food security measurement in U.S. households and communities.
