The 2021 report reported a sharp jump in hunger caused by the COVID-19 pandemic.

It warned that if nothing was done to counter the adverse trends of the past six years, the number of people suffering from chronic hunger could rise by over 150 million by 2030. The 2020 edition instead looked at the prospects of achieving the hunger related Sustainable Development Goal (SDG). The 2019 SOFI report found a strong correlation between increases in hunger and countries that had suffered an economic slowdown. The 2018 edition focused on extreme weather as a primary driver of the increase in hunger, finding rising rates to be especially severe in countries where agricultural systems were most sensitive to extreme weather variations. The FAO's 2017 report discussed three principal reasons for the recent increase in hunger: climate, conflict, and economic slowdowns. While most of the world's people continue to live in Asia, much of the increase in hunger since 2015 occurred in Africa and South America. In 2020, due to the COVID-19 pandemic, there was a massive increase, resulting in nearly 770 million people suffering from malnutrition.

According to the FAO's 2021 The State of Food Security and Nutrition in the World (SOFI) report, the number of people suffering from chronic hunger began to rise gradually between 20. While progress was uneven, by 2014, the threat of extreme hunger had receded for a large portion of the world's population. In the decades following World War II, technological progress and enhanced political cooperation suggested it might be possible to substantially reduce the number of people suffering from hunger.

In many cases, hunger resulted from food supply disruptions caused by war, plagues, or adverse weather. Throughout history, portions of the world's population have often suffered sustained periods of hunger. The Hunger March sculptures in Copenhagen
