A biography or simply bio is a detailed description or account of a person's life. It entails more than basic facts like education, work, relationships, and death—a biography also portrays a subject's experience of these events. Unlike a profile or curriculum vitae (résumé), a biography presents a subject's life story, highlighting various aspects of his or her life, including intimate details of experience, and may include an analysis of the subject's personality.
Biographical works are usually non-fiction, but fiction can also be used to portray a person's life. One in-depth form of biographical coverage is called legacy writing. Works in diverse media—from literature to film—form the genre known as biography.
