2013 Global Hunger Index

A APPENDIXES

Data Sources and Calculation of the 1990, 1995, 2000, 2005, and 2013 Global Hunger Index Scores All three index components are expressed in percentages and weighted equally. Higher GHI scores indicate more hunger. The index varies between a minimum of 0 and a maximum of 100, but these extremes do not occur in practice. The maximum value of 100 would be reached only if all chil- dren died before their fifth birthday, the whole population was undernour- ished, and all children under five were underweight. The minimum value of zero would mean that a country had no undernourished people in the population, no children under five who were underweight, and no children who died before their fifth birthday. The table below provides an overview of the data sources for the Global Hunger Index.

THE GLOBAL HUNGER INDEX IS CALCULATED AS FOLLOWS:

GHI = (PUN + CUW + CM)/3 with GHI: Global Hunger Index PUN: proportion of the population that is undernourished (in %)

CUW: prevalence of underweight in children younger than five (in %)

CM: proportion of children dying before the age of five (in %)

c Data collected from the year closest to 1990; where data for 1988 and 1992, or 1989 and 1991, were available, an average was used. The authors’ estimates are for 1990. d Data collected from the year closest to 1995; where data for 1993 and 1997, or 1994 and 1996, were available, an average was used. The authors’ estimates are for 1995. e WHO 2013 data are the primary data source, and UNICEF/WHO/World Bank 2012; UNICEF 2013a, b; UNICEF 2009; and MEASURE DHS 2013 are secondary data sources. f Data collected from the year closest to 2000; where data for 1998 and 2002, or 1999 and 2001, were available, an average was used. The authors’ estimates are for 2000. g Data collected from the year closest to 2005; where data for 2003 and 2007, or 2004 and 2006, were available, an average was used. The authors’ estimates are for 2005. h The latest data gathered in this period.
