This report analyses and assesses efficient approaches to discourage demand for the services provided by victims of human trafficking for sexual exploitation, based on a greater understanding of experiences, attitudes and motivations of the people who purchase sex. We wanted to gather sufficient knowledge to inform interventions linked with the decision to purchase sex and, in particular, to purchase sex from a vulnerable individual who could be a victim of human trafficking. The research will inform strategies to reduce demand for the services of trafficked women and girls in the five participating countries (Cyprus, Finland, Ireland, Bulgaria and Lithuania).
