A recent post on the Times Online titled 'Crime levels in each street go on internet' discusses how people will be able to check their local street crime as part of a new kind of digital neighbourhood watch:
"HOUSEHOLDERS will be able to go online and check crime levels in the streets around their homes using data issued yesterday.
Eventually an annual “Domesday Book” of crime across England and Wales will be available through the Home Office and the Office for National Statistics. Figures for recorded crime from 13 forces were issued in the first test of the plan.
The figures are based on a calculation known as “middle layer super output areas”, which represent groupings of about 7,000 inhabitants, worked out using postcodes, the census and police records."
