About the UCR Crime Index
The UCR Crime Index is a collection of selected offenses used by the FBI to measure changes in crime reported to police. These offenses include murder, rape, robbery, aggravated assault, burglary, larceny, arson, and auto theft. According to the FBI, Arson statistics are included in trend, clearance, and arrest tables throughout Crime in the United States, but they are not included in any estimated volume data. According to the UCR reporting systems, the “Hierarchy Rule” governs multiple offense reporting. If more than one crime was committed by the same person or group of persons and the time and space intervals separating the crimes were insignificant, then the crime highest in the hierarchy is the only offense reported.
