Sub-Saharan Africa consists of 46 countries and covers an area of 9.4 million square miles. One out of seven people on earth live in Africa, and the continent’s share of the world’s population is bound to increase because Africa’s fertility rate remains higher than elsewhere.
Nigeria will be bigger than the United States in a few decades.If current trends continue, there will be more people in Nigeria than in the United States by 2050. What happens in Africa, therefore, is important not only to the people who live on the continent but also to the rest of us.
