The United Nations Children’s Fund (UNICEF), World Health Organisation (WHO) and the World Bank jointly compiled this report from global and national data on child nutrition. The joint analysis dataset includes 639 nationally representative surveys from 142 countries/territories. The report covers levels and trends of malnutrition globally, including stunting, wasting, under and overweight. The report is linked to the WHO global database on child growth and malnutrition (www.who.int/nutgrowthdb), where UNICEF and WHO review survey data from the published and grey literature as well as reports from national authorities on a continual basis. This report outlines key facts and figures on the levels of child undernutrition by country and region and tracks progress towards Millennium Development Goal (MDG) indicators.
