* Non-fiction refers to writing that is based on factual information and real events.
* Biographies tell the story of a real person's life, drawing on factual events, dates, and sources.
So, a biography is a type of non-fiction.
What might be confusing is:
* Biographies often use storytelling techniques: They might include dialogue, descriptions, and interpretations to make the person's life more engaging and vivid.
* Biographies sometimes have a point of view: The author may have a particular perspective on the person they're writing about, which can influence how the story is told.
However, these elements don't make a biography any less non-fiction. Even with storytelling, a biography should be grounded in verifiable facts and evidence.
