Brothel Complexes, Jakarta, Indonesia

UNICEF estimates that 30 percent of the female prostitutes in Indonesia are below 18 years of age. The ILO puts the total number of child prostitutes in Jakarta at 5,000; according to the Jakarta city government, this is concentrated in Prumpung (North Jakarta), Grogol (West Jakarta) Tanah Abang (Central Jakarta), Block M (South Jakarta), as well as Jatinegara and Ciracas (both East Jakarta). Child sex tourism is a problem, especially on the resort islands of Bali and Batam.
History
Little is known about precolonial Indonesia's prostitution, although the purchase of sex slaves and "quasi-contractual" sexual relations are thought to have occurred. Following the spread of Islam in Indonesia, prostitution is thought to have increased due to Islam's disapproval of contractual weddings. Javanese kings kept large stables of concubines, while Balinese widows without familial support could be prostituted by their king.
