خلاصه	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.	A household livelihood survey is an instrument designed to capture the full portfolio of activities, income sources, assets, and expenditures through which a household secures its living. Rooted in the rural-livelihoods literature associated with Frank Ellis and in global comparative income studies such as the CIFOR Poverty Environment Network, it measures welfare and resilience by mapping the diversity of a household's economic activities — farming, wage labour, self-employment, environmental harvesting, transfers, and remittances — rather than reducing the household to a single income or consumption figure.
