Chil pornography refers to pornographic material depicting children in a pornographic context. Children are sexually abused in the production of child pornography when sexual acts are photographed. The effects of abuse in child pornography are compounded by the wide distribution of the photographs of the abuse. Legal definitions of child pornography generally refer to any pornography involving a minor, varying by jurisdiction and with regards to the age of consent and other laws. For research purposes, child pornography often refers to any recording (photograph, video, or audio) of sexual activity involving a prepubescent child.
