The World Bank Data Blog post Where the extreme poor live by Marta Schoch, Christoph Lanker and Melina Fleury (10/12/2020) provides the graph copied here.
Although the number of poor people has fallen in many regions, most notably East Asia and Pacific, and more recently South Asia, there has been no reduction in Sub-Saharan Africa, where the regional poverty rate remains above 40% in 2017.
The Middle East and North Africa has also seen an increase in the number of poor in recent years, driven largely by the economies in the region that are affected by conflict.
