Case clearance rates as reported monthly to the FBI’s Uniform Crime Reporting (UCR) program. A case is considered “cleared” when it is cleared by arrest or exceptional means. Cases credited as “cleared” in a given month or year may have been opened in a previous month or year. For this reason, the clearance rate for a given period may be above 100%.
