A "red-light area," also commonly referred to as a "red-light district," is an urban area or neighborhood where prostitution and related activities are concentrated and often tolerated or regulated by local authorities. These areas are typically characterized by the presence of brothels, sex workers, and businesses that cater to the sex industry.
The term " red-light " is thought to have originated from the practice of placing a red light or lantern outside brothels or establishments where sex work was conducted in the past. This red light served as a signal to indicate the presence of such services.
