Africa's Population Will Quadruple by 2100. What Does That Mean for its Cities?
New population figures paint a difficult picture for African cities. But there's more to the story than sheer numbers.
Numbers continue to stack up against the world’s poorest continent.
Global population levels are expected to increase from a current figure of 7.2 billion to nearly 11 billion by 2100, according to figures released Thursday by the U.N. Previously, it was believed the world’s population would peak at around 9.5 billion. Nearly all of this new growth, meanwhile, will occur in Africa, which is expected to quadruple in size.
