CrimeStats

CrimeStats helps you see where crime risk is highest and where it is lowest, so you can choose sites, set insurance rates and plan services with confidence. The product includes 30 variables, with historical values from 2010, current-year estimates and five-year projections.

CrimeStats is built on CAP Index’s CRIMECAST^® methodology, which uses statistical modelling to estimate the likelihood of crime. The model links demographic factors such as housing, income and education with historical crime data and survey inputs. It does not use race, religion or gender data.

The result is an index-based score ranging from zero to 2,000, where 100 represents the average risk. Scores are available at the census block group, tract, ZIP code and ZIP+4 level across the U.S.

ZIP code and ZIP+4 values are calculated using CAP Index’s one- or three-mile radius methodology.

Methodology

One-mile ZIP and ZIP+4 scores use either a one-mile radius or a population threshold of 25,000. Use this method for residential real estate and service planning.

For the three-mile methodology, the inner radius contributes two-thirds of the total score, while the outer radius contributes one-third. This method is typically used to assess crime risk around commercial locations.

ZIP and ZIP+4 files are updated quarterly to reflect changes in the TomTom postal code file. New ZIP or ZIP+4 codes receive new scores, while retired codes are removed.

Block group and census tract indexes are created for crimes within each geography. These files include population counts for 2010, current-year estimates and projections to 2030. They are updated annually and align with the U.S. Census Bureau’s current geography definitions.
