Africa's growing middle class drives prosperity

Sub-Saharan Africa's rising population and economies have led to a growing middle class and, in turn, more spending power which provides "a vast source of potential for prosperity," per experts at the African Development Bank.

The big picture: Since 2000, the wealth of sub-Saharan African nations has been growing much faster than the global average and than that of the more prosperous Northern African nations. And in the next five years, analysts at the International Monetary Fund expect the region's GDP to expand even faster.
