The type of headcount that is conducted when the regular count is incorrect is known as an off count. This procedure is essential for maintaining accurate records of inmate populations within correctional facilities, ensuring that all individuals are accounted for and that any discrepancies are resolved. When a regular count does not match the expectations—whether due to a miscount, misplacement of inmates, or other errors—an off count is initiated to verify the numbers and rectify any mistakes. This process is critical in maintaining safety and security within the facility, as incorrect counts can lead to risky situations if inmates are unaccounted for.
