Prostitution, though illegal by law, is conspicuously present in the emirate because of an economy that is largely based on tourism and trade. There is a high demand for women from Europe and Asia. According to the "World Sex Guide", a website catering to sex tourists, Eastern European and Ethiopian women are the most common prostitutes, while Eastern European prostitutes are part of a well-organised trans-Oceanic prostitution network. The government has been trying to curb prostitution. In March 2007, it was reported that the UAE has deported over 4,300 sex workers mainly from Dubai.
