The year of the latest published estimates vary by country so you may have to use the time scrollbar to find the most up-to-date figure for a given country. A child is classified as wasted if his or her weight-for-height is more than two standard deviations below the median for the international reference population ages months. The factors which contribute to this weight loss are associated with measures related to both diet and nutrition, and infection.
As a result, wasting is often compounded by conditions of poor nutrition, feeding practices as well as inadequate sanitary conditions. Unlike stunting, wasting can be treated through improved nutritional intakes, healthcare interventions and treatment of infection. The global map of the prevalence of childhood wasting is shown as the share of the under-5 population. In , South Sudan experienced the highest prevalence of wasting, with The prevalence of wasting is typically highest across Sub-Saharan Africa and South Asia, with countries such as India, Sri Lanka, Djibouti, Sudan and Niger recording some of the highest levels greater than 15 percent.
The share of children suffering from wasting has been declining. If we compare our global map in the early s to a decade later, we see the number of countries with a prevalence greater than 15 percent has fallen. However, the nature of wasting- exemplified often by rapid weight loss- means that particular short-term events which impact food supplies can disrupt long-term trends. This is particularly prevalent in countries with poor political stability; for example, we see a large spike in childhood wasting in the Democratic Republic of Congo during the late s-early s during the Second Congo War.
Undernourishment, or the incidence of being underweight for age, can include children who are stunted, wasted or suffering from insufficient energy intake over a longer period of time. In the chart we see the share of children under-5 who are defined as underweight for their age across world regions since Overall, we see a steady decline at the global level, falling from around 25 percent in to 15 percent in South Asia- despite having the highest regional prevalence- has made significant progress over the last few decades, reducing undernourishment by 20 percentage points from The rate of undernourishment in Sub-Saharan Africa has also fallen notably, from 30 percent in to below 20 percent in Rates in East Asia, Latin America, North Africa and the Middle East are notably lower than South Asia and Sub-Saharan Africa, but have also seen significant declines, each more than halving the prevalence of undernourishment since As we have explored above, there are a number of indicators by which we can measure and track progress related to malnutrition.
The Global Hunger Index attempts to assess the multidimensional nature of hunger, by combining four key indicators of malnutrition into a single index score. The index reflects scoring by country on a point scale where 0 is the best score no hunger and the worst. In the map we see the global map of GHI scores, with a time range of , , and , and Geographically we see that GHI scores are highest i.
However, if we track progress in GHI scores through time, we see definitive improvements across all regions. In other regions, countries have typically shifted from moderate-to-serious in down to low-to-moderate in recent years. Although it would be vital for our understanding of global development we are lacking historical data on hunger and malnourishment.
The history of famines as the most extreme episodes of hunger gives some indication and is dealt with in a separate entry on Our World in Data. Our most concrete and well-established sources of data on hunger and undernourishment begin in This is strongly related to the fact that our global progress indicators on hunger reduction are tracked based on the Millennium Development Goals MDGs , and the subsequent Sustainable Development Goals SDGs , which have a baseline year of During this period, the standard FAO methodology for the estimation of malnourishment has been revised for improved accuracy for the correction see here.
To our best knowledge, estimates of prevalence prior to have not been updated and published based on the revised methodology. However, to provide some sense of how malnutrition has changed over a longer timeframe, we have extended the latest data on undernourishment backwards with FAO estimates, using previous methodologies, for and Estimates of the prevalence of undernourishment differ between these two reports.
The report estimates a prevalence of 37 percent in , reducing to 28 percent in ; 8 the report instead estimates a reduction from This reflects a considerable uncertainty of these estimates and this aspect has to be taken into account as indicated in the subtitle of this chart. Given the uncertainty in these earlier estimates, what can we say about how undernourishment has changed through time?
Whilst specific figures for the level of undernourishment differ between sources, they do agree on the direction of change. Both sources report a consistent downward trend, with similar rates of reduction. The share of undernourished people in the developing world has been declining over this longer timeframe, but there are no confident figures on how many people were undernourished at each point in time.
This gives us estimated trends dating back to for undernourishment in developing countries; but do we have even earlier estimates? FAO figures of undernourishment date back to , the year of its first international summit. Box Washington, D. How many people are there in the world? What is the number of hungry people in the world?

Action Against Hunger is the only international non-government organization solely focused on reducing and eliminating hunger and undernutrition. We treat more children suffering from severe acute malnutrition than any other NGO. We also work to prevent hunger, targeting its root causes and enabling communities to build long-term resiliency. Action Against Hunger works not only to treat acutely malnourished children through a community-based approach, but also to improve child survival and prevent undernutrition by addressing its underlying causes.
Our technical expertise is internationally renowned, due to our 40 years of operational experience in countries with the highest burdens of hunger and to our contributions to developing revolutionary nutrition products and field testing treatment protocols that have become international best practice. We aim to increase the number of children worldwide who are screened and treated for undernutrition and to build the capacity of local health systems to treat undernutrition.
We are committed to research, partnerships, and learning that will allow us to continually improve policy and practice to help achieve the global goal of ending undernutrition in all its forms by Action Against Hunger is leading a global movement to end hunger in our lifetimes. It innovates solutions, advocates for change, and reaches 25 million people every year with proven hunger prevention and treatment programs. As a nonprofit that works across 50 countries, its 8, dedicated staff members partner with communities to address the root causes of hunger, including climate change, conflict, inequity, and emergencies.
It strives to create a world free from hunger, for everyone, for good. With the generous support of people like you, our emergency teams are helping save lives, providing lifesaving treatment to malnourished children and delivering urgent food and water.
Together, we can take urgent action to prevent children from sliding even deeper into tragedy. The consequences are borne by others: Expansion of deserts, soil erosion, water scarcity and extreme weather phenomena as a result of climate change are becoming particularly apparent in countries that already suffer from hunger and poverty.
Undernourishment is not only a consequence of poverty, it also causes poverty, by being passed on from generation to generation — a vicious circle. If a child already suffers from malnutrition in the womb, it has little chance of catching up on its underdevelopment. It often has a weakened immune system and is thus more susceptible to infectious diseases.
The physical and mental development of the child is restricted, it has more difficulty concentrating and produces poorer school results. In addition, a malnourished child is also more prone to developing chronic diseases in adulthood. Both tend to lead to reduced physical and mental capacity in adulthood.
And so earning opportunities decrease and the risk of poverty increases — the cycle continues. Welthungerhilfe presents the Global Hunger Index. Aquatic animals are a renewable resource that can feed people indefinitely if they are managed sustainably.
