The 2013 Global Hunger Index (GHI), which reflects data from the period 2008–2012, shows that global hunger has improved since 1990, falling by one-third. Despite the progress made, the level of hunger in the world remains “serious,” with 870 million people going hungry, according to estimates by the Food and Agriculture Organization of the United Nations. The policy recommendations in this report offer a path forward for the international development, humanitarian, and donor communities; for country-level policymakers in food-insecure countries; and for development and humanitarian practitioners.

The developing world has made progress in reducing hunger since 2000. The 2015 Global Hunger Index (GHI) shows that the level of hunger in developing countries as a group has fallen by 27 percent. Yet the state of hunger in the world remains serious. This marks the tenth year that IFPRI has assessed global hunger using this multidimensional measure. This report’s GHI scores are based on a new, improved formula that replaces the child underweight indicator of previous years with child stunting and child wasting. This change reflects the latest thinking on the most suitable indicators for child undernutrition, one of three dimensions of hunger reflected in the GHI formula. Across regions and countries, GHI scores vary considerably. Regionally, the highest GHI scores, and therefore the highest hunger levels, are still found in Africa south of the Sahara and South Asia. Despite achieving the largest absolute improvements since 2000, these two regions still suffer from serious levels of hunger. Levels of hunger are alarming or serious in 52 countries. Most of the eight countries with alarming GHI scores are in Africa south of the Sahara. While no countries are classified in the extremely alarming category this year, this high level of hunger could still exist. Due to insufficient data, 2015 GHI scores could not be calculated for places that recently suffered from high levels of hunger, including Burundi, Comoros, Democratic Republic of the Congo, Eritrea, Somalia, South Sudan, and Sudan. 2015 Global Hunger Index Interactive App: http://ghi.ifpri.org

The 2017 Global Hunger Index (GHI) shows long-term progress in reducing hunger in the world. The advances have been uneven, however, with millions of people still experiencing chronic hunger and many places suffering acute food crises and even famine. According to 2017 GHI scores, the level of hunger in the world has decreased by 27 percent from the 2000 level. Of the 119 countries assessed in this year’s report, one falls in the extremely alarming range on the GHI Severity Scale; 7 fall in the alarming range; 44 in the serious range; and 24 in the moderate range. Only 43 countries have scores in the low range. In addition, 9 of the 13 countries that lack sufficient data for calculating 2017 GHI scores still raise significant concern, including Somalia, South Sudan, and Syria. To capture the multidimensional nature of hunger, GHI scores are based on four component indicators—undernourishment, child wasting, child stunting, and child mortality. The 27 percent improvement noted above reflects progress in each of these indicators according to the latest data from 2012–2016 for countries in the GHI.

The 2016 Global Hunger Index (GHI) presents a multidimensional measure of national, regional, and global hunger, focusing on how the world can get to Zero Hunger by 2030. The developing world has made substantial progress in reducing hunger since 2000. The 2016 GHI shows that the level of hunger in developing countries as a group has fallen by 29 percent. Yet this progress has been uneven, and great disparities in hunger continue to exist at the regional, national, and subnational levels. Levels of hunger are still serious or alarming in 50 countries. The highest hunger levels are still found in Africa south of the Sahara and South Asia. Although GHI scores for these two regions have declined over time, the current levels remain close to the alarming category. Africa south of the Sahara has achieved the largest absolute improvement since 2000 and South Asia has also seen a sizable reduction—but the decline in hunger must accelerate in these regions if the world is to achieve Zero Hunger by 2030. The 2016 report, with an essay from United Nations Special Adviser David Nabarro, hails the new paradigm of international development proposed in the United Nations’ 2030 Agenda for Sustainable Development, which envisages Zero Hunger by 2030, as one goal among 17, in a holistic, integrated, and transformative plan for the world. To get to Zero Hunger while leaving no one behind, the 2016 GHI highlights the importance of identifying the regions, countries, and populations that are most vulnerable to hunger and undernutrition so progress can be accelerated there.

As the world approaches the 2015 deadline for achieving the Millennium Development Goals (MDGs), which include a goal of reducing the proportion of hungry people by half, the 2010 Global Hunger Index (GHI) offers a useful multidimensional overview of global hunger. The 2010 GHI is the fifth in an annual series that records the state of global, regional, and national hunger. The 2010 GHI shows some improvement over the 1990 GHI, falling by almost one-quarter, but overall the index for hunger in the world remains at a level characterized as serious. The GHI captures three dimensions of hunger: insufficient availability of calories, shortfalls in the nutritional status of children, and child mortality. Accordingly, the Index includes the following three equally weighted indicators: the proportion of people who are undernourished, as estimated by the Food and Agriculture Organization of the United Nations (FAO); the prevalence of underweight in children under the age of five, as compiled by the World Health Organization (WHO); and the under-five mortality rate, as reported by the United Nations Children's Fund (UNICEF). The 2010 Index reflects data from 2003 to 2008, the most recent global data available on the three GHI components.
