The government has revamped the police.uk website with a fresher look and new functions, including better crime mapping.
The government said the new site will give the public more access to information about crime problems and how they are dealt with in their area.
Citizens can get an email informing them when crime data for their area is updated, and they will have the ability to compare the performances of their local police with similar forces.
There is also crime prevention advice relating to specific offences which site users search for.
The government says the site has received 634 million hits since it was created in 2011, and it continues to attract more than 471,000 visits per month, it said.
People can use police.uk to set up personalised "crime maps" - information on crime, anti-social behaviour and criminal justice outcomes - which they can then share with other website users.
Home secretary Theresa May said: "Detailed, street-level crime maps are one of the IT successes of this government. Re-launching police.uk with a new look and new functions will give the public even more access to information about crime and how it is dealt with in their community."
