The ratio of offenders supervised by Essex probation area to Essex probation staff as at 31 March each year is as follows. The ratio between the number of offenders and offender management staff only is also provided:
All staff:offenders Offender Management staff:offenders 2005 1:11 — 2006 1:12 1:47 2007 1:14 1:50 2008 1:16 1:49 2009 1:15 1:49
The number of offenders includes some in custody who would be subject to probation supervision on release. Essex probation area restructured its staff grades in 2006 and introduced a split between offender managers and staff who undertook intervention work. Therefore it is not possible to provide the ratio between offender managers and offenders for 2005.
