Naming the Zones of Sexual Commerce

This article examines the historical origins of the term red-light district. It argues that red lights became associated with prostitution in the United States not only because of red’s popularity in the decor of nighttime businesses but also because of color symbolism popularized by the transportation revolution. As red signal lights on railroads came to indicate “stop—danger,” people accustomed to viewing prostitution as a moral and physical threat read that symbolism onto nighttime businesses’ existing practices of display. Meanwhile, places of prostitution that were located near railroad tracks in the American West embraced the red light as a form of advertising. The red light’s simultaneous status as a lure and warning captured ambivalent responses to prostitution. As a result, it became a potent symbol of late nineteenth-century efforts to keep the sex trade at arm’s length while also treating it as ineradicable. When city officials tried to control the harms of prostitution by segregating it, the products of their efforts came to be known as “red-light districts.” Although the term has in some ways transcended its roots, scholars should be conscientious about their use of it given its implicit moralization of both the sex trade and urban space.
