The current study was commissioned by the Drug Policy Alliance for the purpose of examining the New Jersey jail population and developing a population profile. The population profile is intended to describe the population in terms of demographics, custody status, offense characteristics, bail status, and any other relevant information. The goal of the study is to use this profile to identify opportunities to responsibly reduce New Jersey's jail population while maintaining public safety and the integrity of the judicial process. To conduct the study, data were requested and received from the New Jersey Administrative Office of the Courts ("AOC"). The AOC maintains the County Corrections Information System (CCIS) for which 19 of the 21 counties contribute inmate data (Bergen and Passaic counties do not provide data to CCIS). In addition, an informal survey was conducted of all county correctional facilities and the New Jersey Department of Corrections' Office of County Services (NJDOC-OCS) was consulted to obtain more detailed information on the individual jail facilities. The current report includes a description of the NJCJS, an overview of criminal justice system trends and key stakeholder agencies, a detailed population profile, and a summary of findings.
