The chart show trends in malnutrition in 41 countries, in 4 regions covering one half of children under five years old in the developing world. Countries with under five population below one million are not included, even where trend data were available.

Note: Malnutrition is measured as the percentage of under-five children below -2 standard deviations of the median value for the National Center for Health Statistics (NCHS) reference population for weight-for-age. Rates have been adjusted for age; data for some countries reflect rates for the under-three population.
