Prostitution in Spain is not addressed by any specific law, but a number of activities related to it, such as pimping, are illegal. In 2016, UNAIDS estimated there to be 70,268 prostitutes in the country,[1] although other estimates put the number higher. Most prostitutes in the country are immigrants.[2][3][4][dubious – discuss] The sex industry in Spain is estimated to be worth €3.7 billion.[5]
