Starvation Statistics

Half the battle is fought long before hunger looks dramatic. From 258 million people facing acute food insecurity in 2022 and 320 million peaking in 2022 to 2023 to 95% of stunting concentrated in low and middle income countries and water scarcity affecting 1.0 billion people, this page maps how deprivation, conflict, and chronic malnutrition translate into child deaths and fast rising risk.

About 258 million people were facing acute food insecurity in 2022, but the most alarming part is how concentrated the risk becomes as conditions worsen. From 5.7 million child deaths in 2020 linked to undernutrition to millions more in IPC emergency and crisis phases across countries like Yemen and Somalia, the data makes hunger feel less like a background problem and more like an escalating emergency. We gathered the key starvation and nutrition indicators to show exactly where it hits, who is most at risk, and why the causes keep multiplying.
