Precisely CrimeIndex (US) data measures the likelihood of where crime may occur by 11 crime types for all block groups in the United States. The specific crime variables measured are:
Overall Crime (a composite measure based on all crime types)
Violent Crime Score
- Murder
- Rape
- Robbery
- Aggravated Assault
Property Crime Score
- Burglary
- Larceny-Theft
- Motor Vehicle Theft
- Arson
Each crime variable includes both a numerical score – where higher values denote the increased likelihood of criminal activity – and a qualitative categorization that helps explain the relative crime level when compared to the Nation as a whole. A State-wise score is also provided to allow users to perform within-State comparison of geographic areas. This set of variables (crime scores and qualitative categories) has been bundled with Block Group boundaries to create the CrimeIndex (US) data product.
