Urbanisation

A Goldman Sachs report says that half of the world's population now lives in cities. The largest at 35m people is greater Tokyo, followed by Mexico City, New York-Newark, San Paolo (home to nearly 10% of the population of Brazil) and Mumbai all between 15-20m. They predict that Mumbai will overtake San Paolo by 2020 and also that Delhi will expand from 15m to 25m. Let's hope the quality of the call centres improves exponentially.
