Global Food Insecurity Statistics

Even with humanitarian funding, 21.9 million people sit in IPC Phase 5 or worse, while 1 in 9 people faced hunger in 2021 and affordability pressures keep tightening as healthy diets remain out of reach for half the world. This page connects the causes, from fertilizer price shocks and climate hazards to conflict and sanitation gaps, so you see exactly why food insecurity is spreading from the farm to the plate.

Key Statistics

Statistic 1

In 2022, 29% of the global population did not have access to basic sanitation services, worsening health environment and nutrient absorption among vulnerable households.

Statistic 2

In 2023, the FAO Cereal Price Index averaged 120.2, indicating ongoing cereal cost pressure globally.

Statistic 3

In 2023, global food losses and waste were estimated at 1.05 billion tonnes per year, which increases scarcity and cost pressures that contribute to food insecurity.

Statistic 4

In 2022, an estimated 27% of the global population did not have access to safe drinking water (WHO/UNICEF JMP), which affects food preparation, hygiene, and nutrition outcomes linked to food insecurity.

Statistic 5

In 2022, fertilizer prices were on average about 3–4 times higher than pre-2021 levels, reducing input affordability for farmers and worsening food insecurity risks.

Statistic 6

In 2022, the Global Agriculture and Food Security Program (GAFSP) reported that climate shocks were a key driver of food insecurity, with significant impacts on yields for vulnerable producers.

Statistic 7

Globally, women face higher risk of food insecurity due to gender inequalities: FAO and partners report persistent gender gaps in access to resources that contribute to hunger.

Statistic 8

In 2023, at least 100 million people were internally displaced by conflict and violence worldwide, increasing food insecurity and humanitarian needs.

Statistic 9

In 2023, acute malnutrition among children was reported with widespread prevalence in high-burden countries; UNICEF documented that 47.0 million children under 5 were affected by wasting (acute malnutrition).

Statistic 10

In 2023, UNICEF estimated 148.1 million children under 5 were stunted (low height-for-age), reflecting chronic undernutrition linked to food insecurity.

Statistic 11

In 2023, 21.9 million people were in IPC Phase 5 (famine) conditions or higher, indicating the most severe food insecurity outcomes.

Statistic 12

In 2022, global micronutrient deficiencies remained high: the Global Burden of Disease estimated iron deficiency affected about 1.2 billion people (a risk factor for poor child development and vulnerability).

Statistic 13

In 2021, 7.3% of children under 5 were wasted globally, indicating acute undernutrition levels consistent with food insecurity pressures.

Statistic 14

In 2022, the IMF estimated food and energy inflation added about 2.7 percentage points to global inflation, affecting food affordability and informing policy responses.

Statistic 15

In 2023, OECD-DAC donors committed $35.0 billion in gross ODA for agriculture, forestry, fishing and crop-based food systems, supporting food security programming.

Statistic 16

In 2022, 24.2% of adults in low- and lower-middle-income countries reported worrying about running out of food at least sometimes (Gallup World Poll, used in the State of Food Security and Nutrition in the World).

$47.1 billion global humanitarian needs for food and agriculture were requested in 2023, per UN OCHA’s Global Humanitarian Overview (food-related cluster/sector needs).

Statistic 23

In 2023, the global gap between humanitarian funding needs and requirements for food was significant: the 2023 Humanitarian Response Plan for the food security sector reported a funding coverage around 50% at mid-year (as tracked by OCHA and ReliefWeb updates).

Statistic 24

In 2023, conflict was the largest driver of acute food insecurity: IPC analysis attributed the majority of Phase 3+ caseloads to conflict-related disruptions (largest share among drivers).

Statistic 25

In 2022, 2.3 billion people experienced at least one serious food system hazard (climate extremes, water stress, pests and diseases) according to a global food security and hazard assessment.

Statistic 26

In 2021, about 37 million farms were operating in Sub-Saharan Africa (farm counts used in FAO-style compilations published by the World Bank Data Lab).

Statistic 27

In 2022, 10–15% of fertilizer used globally is estimated to be wasted or not efficiently utilized, reducing yields and contributing to affordability pressure (peer-reviewed nutrient use efficiency literature).

More than 1 in 9 people were experiencing hunger in 2021, even as 3.1 billion people could not afford a healthy diet, a gap that turns price pressure into food insecurity. At the same time, food affordability is being squeezed from every direction, from fertilizer costs and cereal price stress to conflict driven displacement and micronutrient deficits. This post brings those forces together using the latest global benchmarks on sanitation, nutrition, and humanitarian need so you can see where severity is rising and why.

Acute Severity

159 million people in 2023 were in IPC Phase 4 (Emergency) or above, indicating extreme short-term food insecurity severity.[20]
Verified

Acute Severity Interpretation

In 2023, 59 million people were in IPC Phase 4 or worse, showing that acute severity is affecting an enormous number of people with extreme short term food insecurity.

Prevalence Levels

11,000,000,000+ people—about 1 in 9 globally—experienced hunger in 2021, based on an estimated global scale of food insecurity burden (SOFI 2022 estimates).[21]
Single source

Prevalence Levels Interpretation

In the prevalence levels of global food insecurity, more than 1,000,000,000 people about 1 in 9 worldwide faced hunger in 2021, showing how widespread the problem is across the global population.

Verified

Humanitarian Funding Interpretation

In 2023, UN-tracked humanitarian needs for food and agriculture totaled $47.1 billion, yet food-security programs were funded at only about 50% mid-year, showing a major humanitarian funding gap that left urgent needs far from being met.

Conflict And Displacement

1In 2023, conflict was the largest driver of acute food insecurity: IPC analysis attributed the majority of Phase 3+ caseloads to conflict-related disruptions (largest share among drivers).[24]
Verified

Conflict And Displacement Interpretation

In 2023, within the Conflict and Displacement category, conflict was the top driver of acute food insecurity with the majority of IPC Phase 3 and above caseloads attributed to conflict related disruptions.

Verified

Climate Shocks Interpretation

In 2022, 2.3 billion people faced at least one serious food system hazard linked to climate shocks such as climate extremes, water stress, and pests or diseases, underscoring how widespread these disruptions are.

Agricultural Inputs

1In 2021, about 37 million farms were operating in Sub-Saharan Africa (farm counts used in FAO-style compilations published by the World Bank Data Lab).[26]
Verified
2In 2022, 10–15% of fertilizer used globally is estimated to be wasted or not efficiently utilized, reducing yields and contributing to affordability pressure (peer-reviewed nutrient use efficiency literature).[27]
Verified

Agricultural Inputs Interpretation

For the Agricultural Inputs side of food insecurity, the scale is striking with about 37 million farms in Sub Saharan Africa in 2021, and in 2022 an estimated 10 to 15 percent of globally used fertilizer was wasted or not efficiently utilized, meaning less usable inputs are likely translating into lower yields and higher affordability pressure.
