Over half of Mumbai's population lives in slums, with different types including chawls (small rooms with shared facilities), zopadpattis (squatter settlements), and pavement dwellings. Dharavi is one of the largest slums in the world, founded in 1880, and now home to many pottery and textile industries as well as large recycling operations. Slums in Mumbai generally lack adequate sanitation, water supply, and waste management, leading to frequent epidemics, though the government has initiated some redevelopment plans to address issues.
