Echoing antiurbanites throughout the ages, Mahatma Gandhi said that "the true India is to be found not in its few cities, but in its 700,000 villages" and "the growth of the nation depends not on cities, but [on] its villages." The great man was wrong. India's growth depends almost entirely on its cities. There is a near-perfect correlation between urbanization and prosperity across nations. On average, as the share of a country's population that is urban rises by 10 percent, the country's per capita output increases by 30 percent. Per capita incomes are allmost four times higher in those countries where a majority of people live in cities than in those countries where a majority of people live in rural areas.
