Alex Tabarrok reports,

Private cities are happening now for a reason. Africa, India, and China are urbanizing more rapidly than has ever occurred in human history. In Africa, the number of urban dwellers is projected to increase by nearly 400 million, in India at least 250 million will move to cities and in China more than 400 million will move to cities in just the next 20 years. Not all of these people will move to older cities, which are not always in the right places and which rarely possess anything like the right material let alone the right political infrastructure. The rising middle-class want to live in first-world cities and in many of these countries only the private sector can deliver those cities.
