To rank countries and illustrate trends in hunger worldwide, IFPRI, Concern Worldwide, and Welthungerhilfe developed the Global Hunger Index (GHI), which captures four indicators of hunger: undernourishment, child wasting, child stunting, and child mortality. Using data from the Food and Agriculture Organization of the United Nations (FAO), the World Health Organization (WHO), and UNICEF, the index ranks countries on a 100-point scale, with 0 being the best score (no hunger) and 100 being the worst. The GHI is updated annually to track progress. By highlighting this information, the index serves as a tool for mobilizing political will and promoting effective policies to combat hunger. For more than a decade, the GHI has helped to increase country accountability in order to reduce hunger and undernutrition.
