خلاصه	The Demographic and Health Surveys (DHS) are nationally representative household surveys that provide standardised, internationally comparable data on population, health, and nutrition in low- and middle-income countries. Funded primarily by USAID and implemented through The DHS Program, they use model questionnaires, a complex multi-stage sample design, and a standardised wealth index to produce indicators of fertility, child and maternal mortality, family planning, child nutrition, and disease prevalence that drive health policy and programme monitoring worldwide.	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.
