Food Security Measurement

Food security measurement comprises a family of survey-based instruments that capture households' or individuals' access to adequate food, distinct from the U.S. USDA Household Food Security Survey Module. The dominant tools — the FAO Food Insecurity Experience Scale (FIES), the Household Food Insecurity Access Scale (HFIAS), the World Food Programme's Food Consumption Score (FCS), and dietary-diversity scores such as the Household Dietary Diversity Score (HDDS) — measure either the lived experience of food insecurity or the quantity and quality of the diet, providing the indicators used for global hunger monitoring and humanitarian targeting.
