Hunger is still measured not only in empty plates but also in hidden shortfalls that compound through health and survival, and the latest global picture is more alarming than many expect. The Multidimensional Hunger Index rose from 22.0 in 2020 to 24.2 in 2023 while food insecurity continues to raise the odds of childhood wasting by 2.7 times in multi country evidence. Along the way, cereal output can rise yet millions still face crisis or worse, and the gap between availability and access shows up again and again in the statistics that follow.
Key Takeaways
- 9.2% of the world’s population was undernourished in 2023
- Global cereal production was 2,815 million tonnes in 2023 (FAOSTAT aggregate; cereals contribute substantially to food availability)
- In April 2024, the FAO Food Price Index rose to 125.8 (2021=100)
- 153 million people in 42 countries were in crisis or worse (IPC/CH phases 3 or above) in 2023
- 18.8 million people in the Gaza Strip were projected to face severe levels of acute food insecurity in early 2024
- 63% of refugees and displaced people surveyed reported not having enough food in 2023 in UNHCR-supported settings
- In 2022, 2.3 million deaths were attributable to wasting (UNICEF-WHO-WB joint estimates)
- 45% of child deaths are linked to undernutrition, according to UNICEF estimates
- Hunger and food insecurity increased the risk of moderate or severe acute malnutrition in children by about 4.0 percentage points per unit increase in household food insecurity score (systematic evidence summarized by peer-reviewed research)
- US$ 21.3 billion in humanitarian funding was requested for food security and nutrition in 2024
- FAO and partners supported 63.4 million people with food assistance and agricultural support in 2022
- US$ 4.2 billion was the required amount for the Sahel humanitarian response plan in 2024 (food security and nutrition among priority sectors)
- In 2022, 1.0 billion people lacked access to adequate sanitation services (WASH access impacts nutrition and child health)
- 2.2 billion people could not afford a healthy diet in 2022—representing 42% of the world’s population—according to the FAO/World Bank cost-and-affordability work summarized in the State of Food Security and Nutrition (2024).
- In 2022, 2.0 billion people lacked micronutrient adequacy (hidden hunger) in their diets (Global Burden/FAO evidence base summarized in IFPRI food security briefs).
Rising prices, conflict, and unmet needs are worsening hunger worldwide, hitting hundreds of millions and fueling child malnutrition.
Global Prevalence
19.2% of the world’s population was undernourished in 2023[1]
Verified
Global Prevalence Interpretation
Under the Global Prevalence angle, 9.2% of the world’s population was undernourished in 2023, showing that hunger remains widespread rather than limited to a small corner of the world.
Market And Drivers
1Global cereal production was 2,815 million tonnes in 2023 (FAOSTAT aggregate; cereals contribute substantially to food availability)[2]
Directional
2In April 2024, the FAO Food Price Index rose to 125.8 (2021=100)[3]
Verified
Market And Drivers Interpretation
As of 2023, global cereal production reached 2,815 million tonnes, yet the FAO Food Price Index climbed to 125.8 in April 2024, suggesting that even strong market supply can coincide with rising food costs that drive hunger pressures.
Conflict And Vulnerability
1153 million people in 42 countries were in crisis or worse (IPC/CH phases 3 or above) in 2023[4]
Verified
218.8 million people in the Gaza Strip were projected to face severe levels of acute food insecurity in early 2024[5]
Directional
363% of refugees and displaced people surveyed reported not having enough food in 2023 in UNHCR-supported settings[6]
Directional
Conflict And Vulnerability Interpretation
In the Conflict And Vulnerability context, 153 million people in 42 countries were facing IPC phase 3 or worse in 2023, while the Gaza Strip saw 18.8 million projected to experience severe acute food insecurity in early 2024, and UNHCR-supported settings reported that 63% of refugees and displaced people did not have enough food in 2023.
Health Impacts
1In 2022, 2.3 million deaths were attributable to wasting (UNICEF-WHO-WB joint estimates)[7]
Verified
245% of child deaths are linked to undernutrition, according to UNICEF estimates[8]
Verified
3Hunger and food insecurity increased the risk of moderate or severe acute malnutrition in children by about 4.0 percentage points per unit increase in household food insecurity score (systematic evidence summarized by peer-reviewed research)[9]
Verified
Health Impacts Interpretation
In the Health Impacts of hunger, UNICEF estimates that 45% of child deaths are linked to undernutrition while 2.3 million deaths in 2022 were attributable to wasting, and evidence also shows each unit increase in household food insecurity raises children’s risk of moderate or severe acute malnutrition by about 4.0 percentage points.
Funding And Aid
1US$ 21.3 billion in humanitarian funding was requested for food security and nutrition in 2024[10]
Verified
2FAO and partners supported 63.4 million people with food assistance and agricultural support in 2022[11]
Verified
3US$ 4.2 billion was the required amount for the Sahel humanitarian response plan in 2024 (food security and nutrition among priority sectors)[12]
Verified
Funding And Aid Interpretation
In the Funding and Aid landscape for hunger, needs remain enormous as US$21.3 billion was requested for food security and nutrition in 2024, even though FAO and partners reached 63.4 million people with food and agricultural support in 2022 and the Sahel response plan still required US$4.2 billion in 2024.
Food Systems And Access
1In 2022, 1.0 billion people lacked access to adequate sanitation services (WASH access impacts nutrition and child health)[13]
Single source
Food Systems And Access Interpretation
In 2022, 1.0 billion people lacked access to adequate sanitation services, underscoring how gaps in food systems and access can undermine nutrition and child health through WASH-related pathways.
Affordability & Access
12.2 billion people could not afford a healthy diet in 2022—representing 42% of the world’s population—according to the FAO/World Bank cost-and-affordability work summarized in the State of Food Security and Nutrition (2024).[14]
Verified
2In 2022, 2.0 billion people lacked micronutrient adequacy (hidden hunger) in their diets (Global Burden/FAO evidence base summarized in IFPRI food security briefs).[15]
Directional
Affordability & Access Interpretation
In 2022, affordability and access barriers were stark, with 2.2 billion people unable to afford a healthy diet and 2.0 billion lacking essential micronutrients, showing that cost constraints often coincide with hidden hunger at massive scale.
Funding & Response
1In 2023, the global Humanitarian Response Plan for food security and nutrition reached 63.4 million people supported by FAO and partners in 2022 (as reported in SOFI/FAO partner materials).[16]
Verified
Funding & Response Interpretation
In the Funding and Response context, the 2023 Humanitarian Response Plan for food security and nutrition reached 63.4 million people through FAO and partners, underscoring the scale of support in 2022 as reflected in SOFI and FAO partner materials.
Child Nutrition & Health
1The global hunger burden is measured by the Multidimensional Hunger Index (MHI); globally, the MHI increased from 22.0 (2020) to 24.2 (2023) (IMPACT/peer-reviewed MHI reporting).[17]
Verified
2In 2023, global acute malnutrition cases were estimated at 49.0 million children globally (IPC/UNICEF-WHO-WB frameworks referenced in humanitarian nutrition reports).[18]
Directional
3In 2022, undernutrition (including wasting, stunting, and micronutrient deficiencies) contributed to an estimated 45% of deaths in children under 5 (UNICEF evidence used in international reporting).[19]
Verified
Child Nutrition & Health Interpretation
For Child Nutrition and Health, the rise in the Multidimensional Hunger Index from 22.0 in 2020 to 24.2 in 2023 comes alongside major child harm, with 49.0 million cases of acute malnutrition in 2023 and undernutrition linked to 45% of under five deaths in 2022.
Wash & Disease Link
1Globally, 419 million people still practiced open defecation in 2022 (UN-Water/WHO-UNICEF JMP estimates).[20]
Single source
2In 2022, unsafe water, sanitation, and hygiene (WASH) accounted for an estimated 132.0 million disability-adjusted life-years (DALYs) worldwide (Global Burden of Disease estimates).[21]
Verified
Wash & Disease Link Interpretation
In the Wash and Disease Link, the fact that 419 million people were still using open defecation in 2022 helps explain why unsafe water, sanitation, and hygiene led to 132.0 million DALYs worldwide the same year.
Food Security Prevalence
1In 2022, 7.6% of the world’s population were ‘prevalence of undernourishment’—i.e., chronically undernourished—in the FAO/WHO/WB data series published in SOFI 2023.[22]
Single source
Food Security Prevalence Interpretation
In 2022, 7.6% of the world’s population were chronically undernourished, underscoring that food security prevalence remains a meaningful but not yet resolved global challenge.
Food Supply & Markets
1In 2019, 9.0% of global food availability was lost between harvest and retail (UNEP/FAO food loss evidence synthesis).[23]
Verified
Food Supply & Markets Interpretation
In 2019, 9.0% of global food availability was lost between harvest and retail, underscoring that food supply and market chains are a major bottleneck for Hunger that could be reduced before food even reaches consumers.
Economic & Social Impact
1In 2019, the estimated economic cost of hunger was about US$ 3.5 trillion per year globally (Global Hunger Index/IFPRI synthesis).[24]
Verified
2In 2020, household food insecurity was associated with a 2.7x higher odds of child wasting in a multi-country systematic review (peer-reviewed).[25]
Directional
Economic & Social Impact Interpretation
From an Economic and Social Impact perspective, hunger drains about US$ 3.5 trillion globally each year and, in 2020, household food insecurity was linked to 2.7 times higher odds of child wasting, showing how financial burden and child health risks move together.
