The bill outlines new requirements for the Massachusetts Department of Correction regarding the collection and reporting of corrections data. It introduces specific categories for counting admissions and releases, including "Pre-Trial/Detainees" and "Criminally Sentenced," which encompass various subgroups such as individuals awaiting trial, those held on bail, and new court commitments. The bill also establishes a "Caseload Snapshot" and a "Recidivism" section, detailing how to classify and report on individuals in custody, including those under community supervision and civil commitments.

Additionally, the bill specifies the counting rules for different populations, ensuring clarity in data reporting. For instance, it emphasizes the need to separate holds for other jurisdictions and pre-arraignment individuals when reporting figures. The recidivism section highlights the rates of new commitments and violations for both males and females, providing a comprehensive overview of the corrections landscape in Massachusetts. Overall, the bill aims to enhance transparency and accuracy in the reporting of corrections data, which is crucial for informed policy-making and resource allocation.
