The Unified Crime Reporting (UCR) Program was conceived in 1929 by the International Association of Chiefs of Police to meet a need for reliable, uniform crime statistics for the nation. In 1930, the FBI was tasked with collecting, publishing, and archiving those statistics. Today, several annual statistical publications, such as the comprehensive "Crime in the United States" are produced from data provided by nearly 17,000 law enforcement agencies across the United States. For a look at the Part 1 crimes reported by the Irving Police Department, access the UCR year to date (PDF).
LexisNexis Community Crime Map
The LexisNexis Community Crime Map resource connects law enforcement with the community to reduce crime and improve public safety. Crime mapping helps the public get a better idea of the crime activity in their area so they can make more informed decisions about how to stay safe.
LexisNexis Community Crime Map goes beyond crime mapping by automatically alerting the public about recent crime activity and by improving communication between the public and law enforcement through anonymous tips. The tool helps empower the public to make better decisions about crime by putting the same technology used by law enforcement to analyze and interpret crime activity into the hands of the public.
You can see the source of the crime data for any incident by clicking on the incident on the map. The information window lists the "Agency" that provided the information. The Metadata tab also lists the source and links to each source's Web page for the incidents that are currently in view.
