A Partnership of UNICEF, WHO, and the World Bank Group has released new joint estimates for child stunting, overweight, underweight, wasting and severe wasting (May 2018 edition) using the same methodology as in previous years. These new estimates supersede former analyses results published by UNICEF, WHO and the World Bank Group. Note the entire time series is updated; for assessing changes over time, comparisons should be made based on the update time series.
Given that country data are at maximum available from surveys conducted in the year previous to when the modelling exercise takes place, in 2018 the joint estimates were derived up to 2017 with extrapolation for stunting until 2025.
The detailed estimates, including an interactive dashboard, are available here.
