According to a study conducted by the Westminster Council, there are between 80 to 100 known brothels operating in the city, although city officials estimate that the actual number is much higher.
As of 2013, the prices charged by sex workers in Westminster had fallen by roughly 50 percent from previous years due to an increase in prostitutes and more competition. Officials believe that the lack of money is causing the workers to accept more dangerous customers in order to make money and increasing their risks.
Between 1990 and 2006, there were at least 26 murders of sex workers that took place in London.
