To produce the Strategic Assessment the community safety researchers draw on a variety of data sources. Through the SPP information sharing framework we are able to share data between partners which is used in the Strategic Assessment. This includes data from Hampshire Constabulary, Hampshire Fire and Rescue Service, National Probation Service, Hampshire and IOW Community Rehabilitation Company and various other local and voluntary services.
Information about the demographic makeup of Portsmouth is collected from the ONS Census and Small Area Population Forecasts (SAPF). Much of our data around substance misuse is retrieved from the National Drug Treatment Monitoring System (NDTMS) as well as from the Society of St. James.
Most of the crime figures in the assessment are based on police data as well as information from the Hampshire & IOW Constabulary Force Strategic Assessment. This local data is then compared with data from similar areas (e.g. Southampton), national data police data as well as national victimisation data from the Crime Survey for England and Wales (CSEW). Data on the outcomes of offences are collected from Hampshire Constabulary and from the Crown Prosecution Service (CPS).
The National Probation Service (NPS), Hampshire and IOW Community Rehabilitation Company (CRC) provide data on probationers and reoffending rates. Finally, data on anti-social behaviour is collected from Hampshire Constabulary, Community Wardens, the Portsmouth City Council Environmental Health Team and police reports as well as data from CSEW.
