Statistics and other information on local crime rates can be accessed, most directly and with the assurance of Government verification, from the FBI-published Uniform Crime Reports. Compiled annually since 1929, the reports issued through the Uniform Crime Reporting (UCR) Program present the statistics related to crime rates throughout the U.S., including specific areas and jurisdictions where crimes are committed and the types of crimes which are committed in this area.
Information and statistics concerning crime rates are generated through this system by the National Incident Based Reporting System and the Summary reporting system. Statistics of this nature are are secured from approximately 17,000 different law enforcement entities throughout the United States.
Furthermore, several non-Government-affiliated services also present information as to local crime rates and statistics, such as through the source of NeighborhoodScout.com. Statistics on crime rates can indicate not just the frequency with which offenses are committed, but also the degree of success enjoyed by law enforcement.
