19 cities with over
20 million population in the
21 st Century.

Supercities are rising -- vast urban hubs that will radically define the world's future economic and cultural landscape. In 1800, less than 3% of the world's population lived in cities, in fact most people lived their entire lives without ever seeing one. By 1900, 150 million people lived in the world's cities; that number has now surged past three billion, and as of last year, more than half the people on earth live in cities. By 2050, it will be more than 2/3 of us. Humans are now predominantly an urban species, but our population, including the public and private sector, is not yet adequately prepared for life in these intensely urban hubs.
