Kamathipura (also spelled Kamthipura) is Mumbai's oldest and Asia's second largest red-light district. It was first settled after 1795 with the construction of causeways that connected the erstwhile seven islands of Bombay. Initially known as Lal Bazaar, it got its name from the Kamathis (workers) of other areas of the country, who were labourers on construction sites. Due to tough police crackdown, in the late 1990s with the rise of AIDS and government's redevelopment policy that helped sex workers to move out of the profession and subsequently out of Kamathipura, the number of sex workers in the area has dwindled. In 1992, Bombay Municipal Corporation (BMC) recorded there were 50,000 sex workers here which was reduced to 1,600 in 2009, with many sex worker migrating to other areas in Maharashtra and real estate developer taking over the high-priced real estate.
