Several definitions have been proposed for prostitution of children. The United Nations defines it as "the act of engaging or offering the services of a child to perform sexual acts for money or other consideration with that person or any other person". The Convention on the Rights of the Child's Optional Protocol on the Sale of Children, Child Prostitution, and Child Pornography defines the practice as "the act of obtaining, procuring or offering the services of a child or inducing a child to perform sexual acts for any form of compensation or reward". Both emphasize that the child is a victim of exploitation, even if apparent consent is given. The Worst Forms of Child Labour Convention, 1999, (Convention No 182) of the International Labour Organization (ILO) describes it as the "use, procuring or offering of a child for prostitution".
