“Most sex work takes place on highways, railways, construction sites, bus stations, farmlands, lodges, and residential homes, and sex workers frequently migrate between these settings. Major red-light areas now only exist in three states in India: Delhi, West Bengal, and Maharashtra. Even in these states, brothel-based sex work has sharply declined since the 1990s, with the rise of abolitionist anti-trafficking movements, police crackdowns, and real-estate redevelopment interests. Much sex work has migrated to streets or become internet- and phone-based,” it said.
