Food security means access by all people at all times to enough food for an active, healthy life.
USDA’s Economic Research Service (ERS) plays a leading role in research on food security and food security measurement in U.S. households and communities. USDA, ERS provides data access and technical support to social science scholars to facilitate their research on food security. USDA, ERS research focuses on:
USDA, ERS has created several interactive charts and graphs about food security and food insecurity. Visit the Interactive Charts and Highlights page for more information.
Webinar: USDA, ERS economist Matthew P. Rabbitt provides an overview of USDA’s annual report on the prevalence and severity of food insecurity in U.S. households in 2023.
Food security research spotlight:
This report is an extension of information provided annually by USDA, ERS on food insecurity across four racial and ethnic groups: White, non-Hispanic; Black, non-Hispanic; Hispanic; and other, non-Hispanic. This study includes American Indian and Alaska Native, Asian, Hawaiian and Pacific Islander, and multiracial groups—including individuals identifying as both American Indian and White, individuals identifying as both Black and White, and other multiracial combinations.
Food security is associated with cognitive function, body mass index, and intentions to stay in the military. Therefore, monitoring food security is paramount to maintaining military readiness. No analyses have been conducted to date on the prevalence of food insecurity for a representative sample of the active duty U.S. military. Studies of individual military installations, however, have demonstrated food insecurity rates between 15 percent and 33 percent. The primary objective of this analysis was to compare a representative sample of active duty U.S. military service members (military population) to civilian adults (civilian adult population), adjusted by demographic variables associated with food insecurity that are available in both datasets.
All USDA, ERS publications related to food security in the United States can be found on the ERS Publications page.
All Household Food Security in the United States annual reports are also available on the History and Background page.
Selected USDA, ERS resources on numerous topics central to food and nutrition security are available on the Nutrition Security Research Resources page.
In 2015, USDA, ERS released the 20th year of statistics on household food security in the United States. USDA, ERS also sponsored a conference to provide an opportunity to reflect on the contributions and effects of the household food security measure. The opening session of the October 21, 2015, conference, titled "Reflecting on 20 Years of Measuring Household Food Security in the United States," is available on video.
A panel discussion followed the opening session. The panel included former staff from USDA, ERS and USDA’s Food and Nutrition Service (FNS) who were instrumental in developing the food security measure, along with outside researchers who also played key roles.
To mark 25 years of food security data collection, USDA, ERS funded a suite of competitive grants through a collaborative research program with Tufts University and the University of Missouri titled “25 Years of Food Security Measurement: Answered Questions and Further Research.” The purpose of the program was to foster research related to the past 25 years of U.S. household food security research and to explore future feasible evidence-based improvements.
Research papers resulting from funded projects were presented at a national conference on April 4, 2022—with a conference recording available here—and are compiled in a journal supplement published in October 2023.
