Projections indicate that the Caucasus and Central Asia, Northern Africa, South-Eastern Asia and Western Asia likely have met the target too. While Southern Asia has the highest underweight prevalence, with approximately one in three children still affected in 2015, the region has experienced the largest absolute decrease since 1990, a 22 percentage-point drop. In sub-Saharan Africa the underweight rate has fallen by only one third since 1990. However, due to the region's growing population, the number of underweight children has actually risen.
