Cairo is one of the world’s megacities

Cairo is one of the world’s megacities with at least 10 mn people, with an estimated population of 19 mn, according to a list compiled by Axios. The list notes that “518 mn people (7% of the global population) now live in megacities of 10 mn or more people. That's a tenfold increase from four decades ago, and it's radically changing the way people live, work and view the world… Now there are 31 megacities … and most of them are in the developing world. The UN projects 10 more will join the list by 2030, and all but one (Bogotá) is in Africa or Asia.”
