Key results
The number of undernourished persons has risen sharply over the past two years, with up to 828 million people in the world facing hunger in 2021.
After remaining virtually unchanged for five years, FAO estimates of the prevalence of undernourishment in the world increased from 8 percent in 2019 to around 9.3 percent in 2020, and then further to 9.8 percent in 2021. Given current estimates of the world population, this implies that up to 828 million people may have faced hunger in 2021 globally.
Across world regions, hunger numbers continue to depict significant disparities. Compared to 2015, the situation has worsened significantly everywhere; in addition to Africa, increases were also seen in Asia (+ 1.1 percentage points) and, of particular concern, in Latin America and the Caribbean (+ 2.8 percentage points).
