Indicator 2.1.1 - Prevalence of undernourishment

The prevalence of undernourishment (PoU) is an estimate of the proportion of the population whose habitual food consumption is insufficient to provide the dietary energy levels that are required to maintain a normal active and healthy life. It is expressed as a percentage. This indicator will measure progress towards SDG Target 2.1.

Target 2.1

By 2030, end hunger and ensure access by all people, in particular the poor and people in vulnerable situations, including infants, to safe, nutritious and sufficient food all year round.

Impact

The PoU offers countries a measure to track progress made in stamping out hunger in a way consistent with the past. Together with indicator 2.1.2, this is ideal for evidence-based policymaking to ensure no one and no area is left behind and to bring the global hunger figure down to zero.

Undernourishment means that a person is not able to acquire enough food to meet the daily minimum dietary energy requirements, over a period of one year. FAO defines hunger as being synonymous with chronic undernourishment.

Key results

The 2030 zero hunger target will not be achieved unless the recent trend is reversed.

According to the latest estimates, 9.2 percent of the world population (or slightly more than 700 million people) were exposed to severe levels of food insecurity in 2018, implying reductions in the quantity of food consumed to the extent that they have possibly experienced hunger. A broader look at the extent of food insecurity beyond severe levels and hunger reveals that an additional 17.2 percent of the world population, or 1.3 billion people, have experienced food insecurity at moderate levels, meaning they did not have regular access to nutritious and sufficient food. The combination of moderate and severe levels of food insecurity brings the estimated total to 26.4 percent of the world population, amounting to about 2 billion people.
