UNICEF-WHO-The World Bank: Joint child malnutrition estimates - Levels and trends

Since 2012 UNICEF, WHO and the World Bank have been reporting joint global and regional estimates of child malnutrition. The inter-agency team regularly revises the joint data sets and updates the global and regional trend estimates, from 1990 to the present. The estimates of prevalence and numbers for child stunting, underweight, overweight, wasting and severe wasting are derived by United Nations (UN), Millennium Development Goal (MDG), UNICEF, WHO regional and World Bank income group classifications.

In 2012 the inter-agency group derived estimates up to 2011, in 2013 up to 2012 and in 2014 up to 2013. The rationale being that country data are at maximum available from surveys conducted in the year previous to when the modelling exercise takes place.
