Volume 472: debated on Tuesday 4 March 2008

To ask the Secretary of State for the Home Department what change there has been in (a) crime and (b) detection rates in (i) each category of offence and (ii) overall in each basic command unit in the last (A) year and (B) five years for which figures are available. (186312)

The available information is given in the tables placed in the House Library. Data from 2002-03 has been used in the calculations rather than using data from five years ago (i.e. 2001-02). This is because data for 2001-02 is not directly comparable with that for later years.

Some forces have re-structured their basic command units which has resulted in many comparisons not being possible.

It should be noted that non-sanction detections that contribute to the percentage change in detection rates 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 detections 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.
