Uniform Crime Reporting Survey (UCR)

Weighted clearance rate of police service, proportion

Weighted clearance rate refers to the number of criminal incidents solved by the police in the year divided by the number of criminal incidents reported in the year. Police can clear an incident by charge or by means other than the laying of a charge. For an incident to be cleared by charge, at least one accused must have been identified and either a charge has been laid, or recommended to be laid, against this individual in connection with the incident. For an incident to be cleared otherwise, an accused must be identified and there must be sufficient evidence to lay a charge in connection with the incident, but the accused is processed by other means for one of many reasons. The weighted clearance rate is based on the same principles as the Police Reported Crime Severity Index (CSI), whereby more serious offences are assigned a higher "weight" than less serious offences. For example, the clearing of homicides, robberies or break and enters would represent a greater contribution to the overall weighted clearance rate value than the clearing of minor theft, mischief or disturbing the peace.

Police service refers to an establishment primarily engaged in maintaining law and order by means of operating police forces and services.
