Explanation:

Sub-Saharan Africa is the most underdeveloped part of the planet, but it is also one of the most populous. This situation creates serious challenges for the weak and often irresponsible governments of the region and makes development difficult.

The region performs poorly in virtually every area measured by the Human Development Index. Although there has been much progress in recent years, the economic development that has started to improve living conditions in Sub-Saharan Africa has been extremely unequal and not benefited all countries.
