About the indicator

The share of people aged 18 and over with a body mass index below 18.5 kg/m². The indicator moves in the direction opposite to obesity, and together they describe what is called the double burden of malnutrition: in many middle-income countries both shares are high at once — underweight persists in the countryside, obesity has already come to the city. The largest values are given by South Asia and the Horn of Africa.

Important: The aggregate by group is weighted by the whole population rather than the adult one. Underweight in adults and undernourishment are different indicators: the first measures the body, the second the intake of calories.
