The Economic Output of the World's Major Metropolitan
Large metropolitan areas are the foci of
activity as well as of global economic output. The
world's 300 largest metropolitan areas account for 19% of
the global population but for 48% of the global GDP. They
tend to dominate national economies, particularly primate
cities such as London, Paris, Moscow, Mexico City, Bangkok,
Lima and Tokyo. Compared with their
population figures, the economic weight metropolitan
areas in developing economies is less prevalent. The global
economy is thus more a network of interacting cities than of
nations trading. A similar rationale applies at the national
level, which are composed of a system of cities.
