CIBRS Group B Data Report

Please read these important data disclaimers before interpreting or downloading the data
This web page includes Group B Arrest data from the California Incident Based Reporting System (CIBRS) beginning on January 1, 2021, for nine local police agencies (Carlsbad, Chula Vista, El Cajon, Escondido, Harbor, La Mesa, National City, Oceanside, and San Diego Police Departments) and the San Diego Sheriff’s Department. CIBRS is the California specific version of the National Incident Based Reporting System (NIBRS), which is the national system for collecting and reporting crime and arrest data in the United States. The information on these arrest reports may change as new information becomes available. The data is subject to change over time, and all data is refreshed every three months. For more information on this CIBRS/NIBRS data please visit the Group A page.
CIBRS/NIBRS requires differing levels of detail for reporting Group A offenses and Group B arrests. Group A offenses include more serious crime categories, such as Rape, Robbery and Homicide and Group B arrests include less serious crime categories such as Loitering, Driving Under the Influence (DUI), and Liquor Law Violations.  Law enforcement agencies must report both incidents (crime cases) and arrests for Group A offenses. However, Group B offenses are only reported when an arrest is made.  The Group B Arrest Report describes only the circumstances of the arrest, and the arrestee data (e.g., his/her age, sex, race, and ethnicity). This report does not include incident data since agencies report only arrests for Group B offenses.

How to Interpret the Data
