The information requested is not collated centrally. Offenders are transferred between probation areas for a variety of reasons, including rehabilitation and victim safety. However, there is no mechanism is place to record centrally the reasons behind these transfers.
To answer the question, each probation area would need to review their case load to establish the number of offenders who have been transferred between probation areas, and then to examine those cases to determine the reasons behind each move. This could be achieved only by incurring disproportionate cost.
