Anime are often classified by target demographic, including children's (子供, kodomo), girls' (少女, shōjo), boys' (少年, shōnen) and a diverse range of genres targeting an adult audience. Shoujo and shounen anime sometimes contain elements popular with children of both sexes in an attempt to gain crossover appeal. Adult anime (josei for women and seinen for men) may feature a slower pace or greater plot complexity that younger audiences may typically find unappealing, as well as adult themes and situations.
