Northern Virginia residents have access to several crime mapping tools, both official and third-party. Here are the most useful ones.
The Fairfax County Police Department provides an interactive crime mapping dashboard through ArcGIS. You can filter by date range and crime category, and the data is updated regularly. Additionally, the City of Fairfax Police Department maintains its own separate crime map at fairfaxva.gov, which is updated weekly and viewable by neighborhood and business district.
For broader coverage, SpotCrime at spotcrime.com covers Fairfax County, Loudoun County, and Prince William County. It aggregates law enforcement data and allows users to set up email alerts for crimes in their area. CrimeGrade.org is another strong option, providing letter grades for neighborhoods and detailed breakdowns of crime types and costs. Furthermore, Nextdoor often surfaces local crime alerts directly from Fairfax County Police, making it a useful supplement to official maps.
