Child pornography is illegal in most countries, but there is substantial variation in definitions, categories, penalties, and interpretations of laws. Differences include the definition of "child" under the laws, which can vary with the age of sexual consent; the definition of "child pornography" itself, for example on the basis of medium or degree of reality; and which actions are criminal (e.g. production, distribution, possession, and/or downloading and viewing of material).[1] Laws surrounding fictional child pornography are a major source of variation between jurisdictions; some maintain distinctions in legality between real and fictive pornography depicting minors, while others regulate fictive material under general laws against child pornography.
Several organizations and treaties have set non-binding guidelines (model legislation) for countries to follow. While a country may be a signatory, they may or may not have chosen to implement these guidelines. The information given in this article is subject to change as laws are consistently updated around the world.
