A research project on the rise of supercities:


"While some say the world is flat, supercities are rising -- vast, intensely urban hubs will radically redefine the world's future macroeconomic and cultural landscape. Most of the world's population right now lives and works in cities. Many more will. It's critical to gain a truer understanding of what's happening: the rise of supercities is the defining megatrend of the 21st Century."
