Mumbai, India’s premier city, and the nation’s financial and industrial capital is going through a crisis. The population of the city is growing at 4.5 percent per annum. Predictably, most growth is by migration from poor, rural areas. In 1960, squatters were estimated to be less than 4 lakhs in a population of 4.5 million. By 1980, their number rose to 4.5 million in a population of 9 million. Greater Mumbai is now the sixth largest mega city in the world, with 16.4 million population.
