The UNICEF, WHO and the World Bank inter-agency team update the joint global and regional estimates of malnutrition among children under 5 years of age each year. These estimates of prevalence and numbers affected for child stunting, overweight, wasting and severe wasting are derived for the global population as well as by regional groupings of United Nations (UN) regions and sub-regions, Sustainable Development Goals (SDG), UNICEF, WHO and World Bank regions, as well as World Bank country-income group classifications.
