Criminal Justice

Regional Criminal Justice Research and Clearinghouse

SANDAG supports local criminal justice planning and policymaking by providing analyses of crime occurrence, crime trends, and responses to crime in the region. Current and historical information about crime patterns and prevention, and crime-reduction strategies are maintained.

The Clearinghouse provides the means to seek and secure research funds from state and federal sources to assess the effectiveness and efficiency of crime control programs. Assistance to member agencies occurs through various avenues: publishing crime and arrest reports, sharing resources and information, quality assurance studies of crime-related data, impact assessments of crime-reduction strategies, long-term evaluations of critical issues, and grant writing assistance for agencies seeking state and federal funding. Through the Clearinghouse, staff also conduct analyses of offender drug use. Please see our Clearinghouse fact sheet for additional information.

Criminal Justice Research Division staff responds daily to requests for crime-related information from elected officials, criminal justice administrators, community agency practitioners, the public, and the media. Crime-related databases are continually updated. To remain current in the field, information resources are maintained on a variety of justice issues, as well as potential state and federal funding sources for local criminal justice operations. On a monthly basis, data from more than 20 public safety agencies are compiled, quality-controlled, and analyzed. Additionally, staff participates as members of several local criminal justice related committees, councils, and strike forces.

Criminal Justice Flash Findings & Bulletins

The Criminal Justice Research Division provides brief monthly flash findings that report on current projects and other topics of interest to criminal justice agencies, school administrators, public officials, city and county administrators, social service and health agencies, and the general public. In addition, the Division also produces CJ Bulletins on arrests, crime, and arrestee drug use on an annual basis, along with other special bulletins. These monthly updates and CJ Bulletins are featured below in PDF format. Flash findings from previous years are available in our Criminal Justice Archive.
