Laws against child sexual abuse vary by country based on the local definition of who a child is and what constitutes child sexual abuse. Most countries in the world employ some form of age of consent, with sexual contact with an underage person being criminally penalized. As the age of consent to sexual behaviour varies from country to country, so too do definitions of child sexual abuse.[1] An adult's sexual intercourse with a minor below the legal age of consent may sometimes be referred to as statutory rape,[2][3] based on the principle that any apparent consent by a minor could not be considered legal consent.
The United Nations Convention on the Rights of the Child (CRC) is an international treaty that legally obligates nations to protect children's rights. Articles 34 and 35 of the CRC require states to protect children from all forms of sexual exploitation and sexual abuse. This includes outlawing the coercion of a child to perform sexual activity, the prostitution of children, and the exploitation of children in creating pornography. States are also required to prevent the abduction, sale, or trafficking of children.[4] As of January 23, 2015, 196 countries have ratified the Convention, including every member of the United Nations except the United States.[5][6]
