Starvation isn’t just about food running out—it’s also about whether people can reliably access nutritious diets. In conflict-affected settings, prevalence of food insecurity was 40% in 2022, while water scarcity affects 1.0 billion people in 2020 and undermines food production. When these pressures compound, they fuel acute hunger and long-term undernutrition that can leave children stunted and vulnerable.
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.
Acute hunger is worsening, with millions in IPC crisis and famine and widespread undernutrition driving child deaths.

Interpretation
Global Hunger Burden Interpretation
In 2021, 22.3% of people in Africa were undernourished, underscoring that the global hunger burden is concentrated in high need regions while the broader scale of deprivation is reflected in 30% of people unable to afford a healthy diet and major child nutrition tolls like 149 million under 5 being stunted in 2020.
