The available information is given in the form of tables showing undetected crime in each financial year from 1998-99 to 2008-09. Tables 1 and 2 show the numbers for undetected homicides; tables 3 and 4 those for undetected sexual offences. As offences detected in the current year may initially have been recorded in an earlier year it is not possible to determine the numbers of undetected crime in a particular year.

It should be noted that non-sanction detections, which contribute to the overall detection rates, have fallen in recent years. This reflects a significant shift by many police forces away from recording detections where no further action is taken. This will have had an impact on the number of crimes which remain undetected.
