The amazing, surprising, Africa-driven demographic future of the Earth, in 9 charts: Right now, with a couple of exceptions, Africa’s population density is relatively low; it’s a very big continent more sparsely populated than, say, Europe or East Asia. That’s changing very quickly. The continent’s overall population is expected to more than quadruple over just 90 years, an astonishingly rapid growth that will make Africa more important than ever. And it’s not just that there will four times the workforce, four times the resource burden, four times as many voters. The rapid growth itself will likely transform political and social dynamics within African countries and thus their relationship with the rest of the world. (More on this further down.)
Asia will continue to grow but its population growth, already slowing, is expected to peak about 50 years from now then start declining. As has happened in the West, rising economies will lead to declining birth rates. And that downturned curve could represent some problematic demographic issues; more also on this further down.
