Dharavi is a slum and administrative ward, over parts of Sion, Bandra(E), Kurla and Kalina suburbs of Mumbai. Sandwiched between Mahim in the west and Sion in the east, is Dharavi. Spread over an area of 175 hectares, Dharavi has a population of more than 600,000 people according to the Time Magazine. BBC suggests it is home to over 1 million people. Dharavi is "Asia's largest slum", but is now rivalled within Mumbai itself by several other slum pockets in terms of size and squalor. In the expensive Mumbai, Dharavi provides a cheap alternative where rents can be as low as 4 US dollars per month. Dharavi exports goods around the world. The total turnover is estimated to be more than 650 million US dollars.
