This is a list of countries by prostitution statistics.
Prostitution is illegal in the majority of African countries. HIV/AIDS infection rates are particularly high among African sex workers.
Nevertheless, it is common, driven by the widespread poverty in many sub-Saharan African countries, and is one of the drivers for the prevalence of HIV/AIDS in Africa. Social breakdown and poverty caused by civil war in several African countries has caused further increases in the rate of prostitution in those countries. For these reasons, some African countries have also become destinations for sex tourism.
Long distance truck drivers have been identified as a group with the high-risk behaviour of sleeping with prostitutes and a tendency to spread the infection along trade routes in the region. Infection rates of up to 33% were observed in this group in the late 1980s in Uganda, Kenya and Tanzania.
In Gambia, prostitution is illegal. The majority of female sex workers are foreigners.
In Asia, the main characteristic of the region is the very big discrepancy between the laws which exist on the books and what occurs in practice. For example, in Thailand prostitution is illegal, but in practice it is tolerated and partly regulated, and the country is a destination for sex tourism. Such situations are common in many Asian countries.
In Japan, prostitution is legal with the exception of heterosexual, vaginal intercourse. Advertisements that detail what each individual prostitute will do (oral sex, anal sex, etc.) are a common sight in the country, although many prostitutes disregard the law.
Child prostitution is a serious problem in this region. Past surveys indicate that 30 to 35 percent of all prostitutes in the Mekong sub-region of Southeast Asia are between 12 and 17 years of age.
