In these papers, ECPAT International critically evaluates terms related to the sexual exploitation of children. For more commentary on such terms, see the forthcoming publication Semantics or substance? Towards a shared understanding of terminology referring to the sexual abuse and exploitation of children. This booklet, published in January 2005, is a collaboration among members of the Sub-group against Sexual Abuse and Exploitation of Children, including ECPAT International. The sub-group is part of the NGO Group for the Convention on the Rights of the Child.
