World Hunger, Severe Food Insecurity Grew in 2021

by Sara Viviani and Julie Ray

Despite hopes that food security -- which suffered major setbacks in 2020 -- would start to recover in 2021, the latest State of Food Security and Nutrition in the World report (SOFI) shows that 2021 brought further setbacks.

World hunger and severe food insecurity grew, making the world's goal of achieving "zero hunger" by 2030 even more unlikely. In fact, according to current projections from the Food and Agriculture Organization of the United Nations (FAO), 8% of the world's population will still be undernourished in 2030 -- just as much as when these goals were first set in 2015.

The report released in July draws on data from many sources, including food security data collected for the FAO in the Gallup World Poll*, to provide the latest update on the world's progress toward ending hunger and ensuring food security in the second full year of the pandemic.

Key Findings

Although the pace slowed, the proportion of people facing hunger continued to rise in 2021.

After remaining basically unchanged for five years, the prevalence of undernourishment** -- the FAO's traditional indicator of the extent of hunger -- increased from 8.0% to 9.3% between 2019 and 2020. It kept rising in 2021, although at a slower pace than the year before, reaching 9.8%.

Two line graphs. First trend line indicates the prevalence of undernourishment globally, from 2005 to 2021. Between 7.8% and 9.3% of the world's population has been undernourished between 2005 and 2020, with the estimated % of undernourishment for 2021 between 8.9% and 10.5% of the global population. Second trend line indicates the raw number of people worldwide who have been undernourished, a value that has fluctuated between 571.6 million and 805.5 million people between 2005 and 2020. In 2021, the estimated number of undernourished is between 701.9 and 828.0 million people.

Hunger continued to increase in most regions of the world. As a share of its population, Africa continued to bear most of the burden, with one in five people -- or an estimated 278 million -- facing hunger in 2021. However, more than half of the people in the world affected by hunger in 2021 -- 425 million -- live in Asia.

The war in Ukraine could make hunger worse for millions.

The war in Ukraine, which involves two of the world's biggest producers in agriculture and staple cereals, could drive hunger numbers even higher in the short and medium term.

FAO simulations suggest that in a severe-shock scenario, 13 million more people could be undernourished in 2022 -- and reach as high as 19 million more in 2023. Populations already facing hunger and food crises -- in sub-Saharan Africa, the Near East and North Africa -- are most at risk of higher undernourishment.

Three bar graphs. These depict the estimated impact of the war in Ukraine on the global number of undernourished people in 2022. The "base" number, which does not take the war in Ukraine into account, is 733.9 million people worldwide. The moderate scenario is 741.5 million people, and the extreme scenario is 747.0 million people.

Overall food insecurity remained mostly unchanged, but severe food insecurity increased.

Moderate or severe food insecurity at the global level has slowly been rising since 2014, when the FAO first started collecting data annually using the Food Insecurity Experience Scale (FIES) informed by Gallup's World Poll and other sources. But in 2020, moderate or severe food insecurity rose nearly as much as it had in the previous five years -- combined.

The 2021 data show overall food insecurity remained stable, but severe food insecurity -- which means people had run out of food or, at worst, gone a day without eating -- rose. Severe food insecurity increased from 10.9% in 2020 to 11.7% in 2021. An estimated 923.7 million people faced severe food insecurity in 2021, up 73.6 million from just the year before.


Moderate and severe food insecurity increased most in Africa, where more than one-third of the total number of people facing severe food insecurity live. An estimated 322 million Africans in 2021 were facing severe food insecurity -- 21.5 million more than in 2020 and 58 million more than in 2019 before the COVID-19 pandemic.

Food insecurity also continued to worsen in Latin America and the Caribbean. Roughly 10 million more people were facing severe food insecurity in 2021 than the year before -- and almost 30 million more were facing severe food insecurity than in 2019. In the region, severe food insecurity has nearly doubled since 2014.

The gender gap in food security widened even further in 2021: 31.9% of women were moderately or severely food insecure, compared with 27.6% of men. In every region except Africa, food security among men improved, while it worsened among women in every region except Asia.

The increase in the gender gap globally from 2020 to 2021 was driven largely by the widening differences in Latin America and the Caribbean, where the gap between men and women increased from 9.4 percentage points in 2020 to 11.3 points in 2021. The gap also expanded in Asia, from 2.7 points in 2020 to 4.4 points in 2021.


Just eight years away from 2030, the latest SOFI report shows the world continues to be headed in the wrong direction in its fight to end world hunger, food insecurity and malnutrition. Although the pace in the increase in hunger slowed in 2021, it continued to rise, and hunger affected tens of millions more people than it did the year before.

The increase in global hunger in 2021 reflects the lingering effects of the COVID-19 pandemic and the unequal pattern of economic recovery that took place last year. Many of the people most affected by the pandemic did not recover the incomes that they lost, which exacerbated existing inequalities and made food security situations worse for populations that were already struggling before the pandemic.

Finding a path forward in these challenging and uncertain times -- as food prices rise and recession looms -- will require governments to start rethinking how they allocate their funding and use the resources they already have to fight hunger.
