Global Database on Child Growth and Malnutrition

Joint child malnutrition estimates - Levels and trends (2015 edition)

UNICEF-WHO-The World Bank Group

In September 2015 the inter-agency team released new joint estimates of child malnutrition using available data up to 2014 and the revised UN population estimates (2015 revision). The same methodology as in previous years was applied with minor refinements. These new estimates supersede former analyses results published by UNICEF, WHO and the World Bank Group.

Given that country data are at maximum available from surveys conducted in the year previous to when the modelling exercise takes place, in 2015 the joint estimates were derived up to 2014 with extrapolation until 2015 for overweight and underweight; and for stunting a further extrapolation until 2025.

    This data set consists of 778 national survey data which were standardized for analysis purpose. Estimates are adjusted where necessary to be nationally representative and to cover the age range 0-5 years. The adjustments are specified in the Notes column. As a result of making these adjustments, prevalence might be slightly different from the survey results reported elsewhere.

Child wasting and severe wasting are very sensitive to change and thus only latest estimates are shown in the interactive dashboard.
