The bill amends Massachusetts General Laws, specifically Chapter 126, Section 40, to enhance the reporting requirements for sheriffs regarding jail and house of correction populations. It introduces a new overview section for the Quarterly Population Report, mandating sheriffs to record and report detailed data on individuals committed to these facilities, including probation central file numbers, state identification numbers, race and ethnicity, and offense-based tracking numbers. The reports must be aggregated quarterly and submitted to public safety officials without identifying information about individual inmates. Additionally, the bill establishes new definitions for critical data points and notes limitations in data collection, particularly regarding case disposition and bail information, which are not owned by the Sheriffs' Offices.

Furthermore, the bill proposes amendments to improve the classification and reporting of individuals based on race and ethnicity, ensuring comprehensive demographic data collection. It introduces new legal language that emphasizes tracking earned time and jail credit, which is essential for understanding incarceration impacts on different demographic groups. The bill also enhances the management and oversight of inmate programming and rehabilitation services, establishing criteria for program evaluation and participant tracking, while emphasizing access to diverse educational and vocational training opportunities. These changes aim to improve transparency, accountability, and the overall effectiveness of rehabilitation programs within the correctional system, ultimately benefiting both inmates and the broader community.
