The Ordnance Survey has teamed with CIFAS last year to show have produced a special report on online fraud including a map on the risk of Identity Theft enabled by e-crime. The CIFAS Fraud Landscape document is here (pdf). This includes maps of Victims of Impersonation in 2011 per thousand people by local authority area.
Another online map is provided by the police in the UK that allows you to view crime in your area or postcode. Unfortunately fraud is grouped under other crimes.
