CSA is the second most urbanised region in the world after North America, with 81% of its population being urban. In addition, 129 secondary cities with 500,000 inhabitants are home to half of the region's urban population . Another 65 million people live in megacities of over 10 million each. The population migrates among cities, resulting in more secondary cities and creating mega regions and urban corridors.
