CrimeStats provides 30 variables related to the rates and risk of crime in 2010, current-year and five-year projections. CrimeStats is derived from CAP Index’s CRIMECAST® database and it uses statistics, demographics and computer modeling to determine the likelihood of crime for any location in the U.S., Canada, and the U.K. CRIMECAST® was developed by correlating a broad array of demographic variables—such as housing, economic and education data (but not race, religion and gender information)—with historical crime data, survey information and other known indicators of crime. The result is an index-based database that provides a crime risk score between zero and 2,000, with an average risk of 100 for every census block group, tract, ZIP code or ZIP+4 in the U.S.
