As the inventory approach provides for ongoing tracking of the management category for each offender it has been possible to add the new concept of the "recently managed offender pool". This is the pool of all offenders managed by Corrections at some time within the last ten years (excludes episodes of remand management without sentence), but who are not currently under Corrections management. This new concept will provide for future enhancements to this report that will shed light on the evolving nature of the offender population of New Zealand.
