Megaregions -- rather than nations -- have become the natural units of the global economy. How is a megaregion defined? Tim Gulden at the University of Maryland's Center for International and Security Studies has used nighttime satellite images of the earth to identify "contiguous lighted areas" that include at least one major metropolitan area. Examples? The Boston-New York-Washington corridor and the Shanghai-Nanjing-Hangzhou triangle. Megaregions are the lit-up regions that produce more than $100 billion in goods and services. 1.2 billion people -- 18% of the global population -- live in the world's 40 megaregions. Combined, they produce 66% of the world's economic activity and 86% of new patents.
