What is the common term used for a person who has been reported as unaccounted for?

The common term used for a person who has been reported as unaccounted for is "missing person." This term is widely recognized and used in law enforcement, legal contexts, and public discussions about individuals whose whereabouts are unknown and who may be in danger or require assistance. It encompasses a broad range of situations, including those who have voluntarily left, those who have been abducted, or those who have disappeared due to unforeseen circumstances. This term carries significant implications for search and rescue operations and the legal processes that follow such cases.

The other options might refer to specific situations or imply a particular context, but they are not the standard terminology used in official reports or investigations regarding individuals who are not accounted for. For example, "disappeared individual" might not convey the urgency or legal implications associated with a missing person status. Similarly, "to be found" is more of a phrase describing the action rather than a term for the individual, and "runaway" specifically refers to someone, usually a minor, who has left home without permission, which does not encompass all scenarios of being unaccounted for.
