This is a maintenance category, used for maintenance of the Wikipedia project. It is not part of the encyclopedia and contains non-article pages, or groups articles by status rather than subject. Do not include this category in content categories. This is a hidden category. It is not shown on its member pages, unless the corresponding user preference (appearance → show hidden categories) is set.

Here is how to decide which category to use on biographical articles:

• If a reliable source gives the person's year of death, use a category such as Category:2025 deaths
• If the person was born more than 115 years ago:
  • If a reliable source says that the person's year of death is unknown, use Category:Year of death unknown
  • If no such source can be found, use Category:Year of death missing
• If the person was born more than 90 years ago but less than 115 years ago:
  • If a reliable source shows that the person was alive at any time during the last ten years, use Category:Living people
  • If no such source can be found, use Category:Possibly living people
