Clearance Rates Dashboard
The FBI UCR program sets guidelines and definitions for what offenses are classified as Part I crimes. This Dashboard is looking at Part I offenses which are serious crimes that occur with regularity in all areas of the country and are likely to be reported to the police. Part I Violent Crime categories include homicide, rape, robbery and aggravated assault. Part I Property Crime categories include burglary, larceny, motor vehicle theft and arson.
Homicides numbers are based on Incidents; they are not based on number of victims. Homicide does not include Vehicular Manslaughter Incidents. Rape numbers are based on Incidents; they are not based on number of victims. Counts are based on Incident Number not Victim/s or Suspects/s involved in the Incident/Case. Incident detail count are based on the life of a case and takes the minimum Occurrence date, and it captures the highest offense of the Incident/Case, for example if Incident 111-111-111 includes a Homicide and a Robbery, this would capture and count only the Homicide and not the robbery. Unfounded Incidents/Cases are removed from the count. Courtesy Reports are Incidents that occurred outside of San Francisco.
If there is no data for a selected date range for a crime category, that crime category may not appear.
Definition of Clearance
In the FBI's Uniform Crime Reporting (UCR) Program, law enforcement agencies can clear offenses in one of two ways: by arrest or by exceptional means. Although an agency may administratively close a case, that does not necessarily mean that the agency can clear the offense for UCR purposes. To clear an offense within the UCR Program's guidelines, the reporting agency must adhere to certain criteria. Clearance rate is calculated by dividing the number of crimes that are "cleared" by the total number of crimes recorded.
