sex worker organisations, labour unions, networks, support groups and programmes. The International Committee for Prostitutes' Rights (ICRP) was founded in Amsterdam in 1985, where the first of a series of World Whores Congresses was hosted the same year, at which the World Charter for Prostitutes' Rights was adopted. It was relaunched as the International Committee for the Rights of Sex Workers in Europe (ICRSE) in Amsterdam in 2005, and drew up another charter of rights for sex workers, with a focus on European countries. TAMPEP, founded in 1993, based in Amsterdam and hosted from Helsinki, calls itself the "European Network for HIV/STI Prevention and Health Promotion among Migrant Sex Workers". The Red Umbrella Fund (RUF) was founded in 2012 as an Amsterdam-based fund making grants to sex workers' rights groups worldwide. In addition, the La Strada International Association (LSI) is an Amsterdam-based anti-trafficking organisation which has the decriminalisation of sex work as a "strategic focus area". Sex trafficking NGOs and police estimated that the number of women and girls trafficked for the purpose of sexual exploitation ranged from 1,000 to 3,600. The Foundation Against Trafficking in Women (STV), an independent NGO that helped victims of trafficking, registered 579 victims in 2006, up from 424 in 2005.

Countries that are major sources of trafficked persons include Thailand, India, the Netherlands, Mexico, China, Nigeria, Albania, Bulgaria, Belarus, Moldova, Ukraine, Sierra Leone, and Romania.

However, an increase in identified presumed victims does not necessarily mean an increase in trafficking but can be caused by, for instance, better awareness and cooperation among the different agencies which come into contact with potential victims. Within the Netherlands, victims are often recruited by so-called "loverboys" – men who seduce young Dutch women and girls and later coerce them into prostitution. The phenomenon was highlighted in 2008 by Maria Mosterd, who published a book about her ordeal as the 12-year-old victim of a loverboy. The truthfulness of this book is disputed, and was the subject of an investigative journalism report. Many victims of human trafficking are led to believe by organized criminals that they
