Detection rates at police force area level have been published for robbery since 1990 and are given in the following tables.

It should be noted that non-sanction detections which contribute to the overall detection rates have fallen in recent years reflecting a significant shift by many police forces away from recording detections where no further action is taken. For this reason overall detection rates over time are not fully comparable.

(1) The National Crime Recording Standard was introduced in April 2002. Figures before and after that date are not directly comparable.

(2) It should be noted that non-sanction detections that contribute to the overall detection rate have fallen in recent years reflecting a significant shift by many police forces away from recording detections of crime where no further action is taken. For this reason overall detection rates over time are not fully comparable. From 1 April 2007 the rules governing recording of non-sanction detections were revised to reduce the scope within which they can be claimed to a very limited set of circumstances.
