Incoming California inmates
This API includes more than 49,000 inmates who were in California's prisons as of March 31. The API includes each inmate's COMPAS score for substance abuse, criminal thinking and education. A score of 1 indicates "low risk," 2 indicates "moderate risk" and 3 indicates "high risk." The API also includes each prisoner's gender, age and crime (the inmate's "principal offense," the conviction that resulted in their prison sentence).
This API can be used to show which crimes (see below) our interactive has categorized as violent, property, controlled substances and other.
This API can be used to retrieve the information used in the main interactive. Each crime is created by grouping similar state criminal statutes (see below) into manageable groups. For each crime, the API returns statistics on the number of incoming inmates whose principal offense is covered by that crime, along with the number of inmates who scored "high risk" in substance abuse, criminal thinking or education. Please note that the data provided by the state is missing many education scores, so a separate count of inmates with any score is provided for substance abuse, criminal thinking and education. This API also includes information about the age, gender and ethnicity of inmates assigned to each crime.
This API can be used to determine which statutes were matched to a given crime. A complete list of crime-to-statute matches is available here, but the API can be used to access this information from your application.
