Dharavi is a locality in Mumbai, Maharashtra, India, considered to be one of Asia’s largest slums. Dharavi has an area of just over 2.1 square kilometres (0.81 sq mi; 520 acres) and a population of about 1,000,000. Dharavi is one of the most densely populated areas in the world.
The Dharavi slum was founded in 1884 during the British colonial era, and grew because the expulsion of factories and residents from the peninsular city center by the colonial government and from the migration of rural Indians into urban Mumbai. For this reason, Dharavi is currently a highly diverse settlement religiously and ethnically. Dharavi is considered one of the largest slums in the world. The low-rise building style and narrow street structure of the area make Dharavi very cramped and confined. Like most slums, it is overpopulated.
