About CrimeMetric
CrimeMetric publishes crime rates per resident for U.S. states, cities, towns and neighborhoods, for 16 crime types, compared with the U.S. rate, with the method and the uncertainty shown. For cities whose police publish incident data, pages also show those records.
Who makes it
CrimeMetric is built and run by Vorp Labs, Inc.
Where the numbers come from
Police agencies' crime reports to the FBI are the base. A model spreads each agency's totals across the 2020 census block groups it serves, using residents, jobs, daytime population, points of interest and, where an agency publishes them, local incident records. The model is tested on places it wasn't trained on, and the method page shows how accurate it is.
What the numbers are, and aren't
- Modeled estimates of reported crime per resident, each with an 80% interval and a confidence level. They aren't counts of every crime, and they aren't safety ratings or grades.
- Rates are per resident, so places where many people work or visit but few live, such as downtowns, can read high.
- Police records are what agencies publish, and agencies count and publish differently. Addresses are generalized to the hundred block and map points to about 100 meters.
How current it is
City, state and crime-type pages show the day they were last updated. The model is rebuilt with each data release, and each city page says when its figures were last modeled ("Model updated"); pages with police records also say the dates their records cover.
Using the numbers
Quote any page's aggregate figures with a link to it, or download the city sample under its own license. Individual police records, and the street and spot lists built from them, need a written contract with us. Data terms
City-level figures from the sample can go in a product under its license. To put figures for any U.S. address or block group in a product, use the API or MCP server.
