Nutrition-based poverty line "(...) is usually determined with reference to a nutritional norm converted into a minimum food basket and income needed to ensure access to such a basket (and, of course, other items of basic needs). People (or households) having incomes below the level thus determined are identified as poor − according to this measure.”
