GLOBAL HUNGER INDEX Information
GHI and its Composition
The Global Hunger Index (GHI) is a multidimensional statistical tool used to describe the state of countries’ situation. The GHI measures progress and failures in the global fight against hunger. The GHI is updated once a year.
The Index ranks countries on a 100 point scale, with 0 being the best score ("no hunger") and 100 being the worst, though neither of these extremes is achieved in practice. The higher the score, the worse the food situation of a country. Values less than 4.9 reflect "low hunger", values between 5 and 9.9 reflect "moderate hunger", values between 10 and 19.9 indicate a "serious", values between 20 and 29.9 are "alarming", and values exceeding 30 are "extremely alarming" hunger problem.
The data used for the 2010 GHI are for the period from 2003 to 2008 – the most recent available global data for the three components of the GHI. The 2010 GHI and the recalculated base value of 1990 GHI are not directly comparable to previously calculated GHI values.
The GHI combines three equally weighted indicators:
- the proportion of the undernourished as a percentage of the population. The data on the proportion of undernourished come from the Food and Agriculture Organization of the UN (FAO) and are for 2004-2006.
- the prevalence of underweight children under the age of five. Data on underweight of children under 5 are based on data collected by the World Health Organization (WHO), UNICEF and MEASURE DHS.
- the mortality rate of children under the age of five. Data on child mortality are for 2008 from UNICEF.
