The CPS records some limited data, identifying the number of victims in the Witness Management System. This is a system used by Witness Care Unit (WCU) staff to manage cases. Not all cases are managed by WCUs and a number of CPS areas do not use this system. It follows that there are many cases for which victim information is not recorded. As a result, it is not possible to correlate data on the sex of victims against data on the sex of defendant.
