Sub-Saharan Africa’s opportunities are vast, and its challenges are persistent. Home to the world’s largest free trade area and a 1.2 billion-person market, the continent is creating an entirely new development path, harnessing the potential of its resources and people.
The region is composed of low, lower-middle, upper-middle, and high-income countries, 18 of which are fragile or conflict-affected. Africa also has 13 small states, characterized by a small population, limited human capital, and a confined land area.
