Acute food insecurity affected 258 million people in 2022. The crisis is geographically concentrated, with millions more in emergency phases across Yemen and Somalia. These statistics detail the scale, regional impact, and drivers of global starvation.
Key Takeaways
- 22.3% of people in Africa were undernourished in 2021 (FAO regional estimate), pointing to regional concentration of hunger and starvation risk
- 30% of people were unable to afford a healthy diet in 2020 (global average estimate), highlighting purchasing constraints that drive starvation risk
- 5.7 million children died in 2020 (UNICEF), and about half of child deaths are linked to undernutrition, implying starvation’s role in mortality
- 1.0% of the population in North America and Europe were undernourished in 2021 — share of people lacking sufficient dietary energy.
- 74% of acute food insecurity caseload in 2022 was in just 10 countries — geographic concentration of severe hunger.
- 47 million people in Yemen were estimated to be acutely food insecure in 2023 — number of people facing acute hunger conditions.
- 2.4 million people in Ethiopia were estimated to be in 'Emergency' (IPC/CH phase 4) in 2023 — acute starvation risk tier.
- 17.7 million people in Somalia were projected to be in Crisis or worse (IPC/CH phase 3+) during 2023 — acute hunger risk in the Horn of Africa.
- 2.3 million deaths were estimated to be attributable to undernutrition among children under 5 in 2020 — mortality outcome related to insufficient intake and nutrition.
- Prevalence of food insecurity in conflict-affected settings was 40% in 2022 (median estimate) — higher baseline risk from instability.
- 45% of child deaths are associated with undernutrition (global, 2020) — portion of mortality linked to insufficient nutrition and starvation risk.
- 1.0 billion people were affected by water scarcity (physical water scarcity) in 2020 — water constraint affecting food production and nutritional outcomes.
- Approximately 8% of all food produced is wasted at the retail and consumer levels worldwide — reduction in available calories that contributes to hunger risk.
- In 2022, conflict was a key driver of hunger in at least 25 countries — major cause linked to severe food insecurity and famine risk.
- FAO estimated that US$60–100 billion per year is needed to end hunger by 2030 — investment requirement for hunger reduction systems.
In 2022, 258 million people faced acute hunger, with hunger driven by conflict, rising costs, and climate impacts.

Nutrition & Health Outcomes9 stats
01
2.3 million deaths were estimated to be attributable to undernutrition among children under 5 in 2020 — mortality outcome related to insufficient intake and nutrition.
02
Prevalence of food insecurity in conflict-affected settings was 40% in 2022 (median estimate) — higher baseline risk from instability.
03
45% of child deaths are associated with undernutrition (global, 2020) — portion of mortality linked to insufficient nutrition and starvation risk.
04
2.6 million children died from causes related to diarrhea in 2019 — diarrhea can be worsened by undernutrition and is associated with starvation vulnerability.
05
Wasting increases the risk of death in children by about 9 times — clinical outcome linked to acute starvation.
06
Stunting is associated with reduced lifetime earnings by about 10% — long-term human capital impact of chronic undernutrition.
07
Vitamin A deficiency affected an estimated 19.0 million preschool children in 2022 — micronutrient deficiency contributing to malnutrition and vulnerability.
08
In 2019, 49% of under-5 deaths were linked to stunting, wasting, and micronutrient deficiencies — portion of mortality attributable to undernutrition.

Chronic hunger is projected to increase by 1–3% globally due to climate change impacts on agriculture by 2050 (depending on scenario) — future risk driver for starvation.
Interpretation
Nutrition & Health Outcomes Interpretation
In the Nutrition and Health Outcomes category, undernutrition is linked to massive child mortality and long-term harm, including 2.3 million deaths in 2020 among under 5s and 49% of under 5 deaths in 2019 tied to stunting, wasting, and micronutrient deficiencies, with the risk likely rising as chronic hunger is projected to increase by 1 to 3% globally by 2050 due to climate change.

02
33.0% of children under 5 in Afghanistan were stunted (2018–2021 estimate), indicating chronic malnutrition consistent with long-term hunger risk
03
95% of stunting occurs in low- and middle-income countries (share of global stunting burden, UNICEF/WHO/WB framing in multiple nutrition advocacy datasets)
Interpretation
Chronic Undernutrition Interpretation

Acute Hunger Burden2 stats
01
19.7 million people in 2022 were classified as experiencing acute hunger (IPC Phase 5) or famine-like conditions, per IPC’s global food insecurity estimates synthesis
02
1.0% of the global population is projected to face famine-level conditions in 2024–2025 (about 10.5 million people) per IPC’s 2024 global update
Interpretation
Acute Hunger Burden Interpretation
Under the acute hunger burden, 19.7 million people were facing IPC Phase 5 or famine like conditions in 2022, and projections suggest this could shrink but still remain severe with about 10.5 million people, or 1.0% of the global population, expected to face famine level conditions in 2024 to 2025.

Food Access Constraints2 stats

30.7% of the global population in 2022 experienced moderate or severe food insecurity (FIES-based estimate)
02
$124 billion annual global food-system losses and waste (retail and consumer levels plus other points in the value chain), highlighting resource loss that worsens hunger risk
Interpretation
Food Access Constraints Interpretation
In 2022, 30.7% of people globally faced moderate or severe food insecurity, showing how major food access constraints persist even as $124 billion in annual global food-system losses and waste further undermine the availability of food needed to reduce hunger risk.
