The bill amends Massachusetts General Laws, specifically Chapter 126, Section 40, to enhance the reporting requirements for sheriffs regarding the population of jails and houses of correction. It introduces a new section titled "Overview of Quarterly Population Report for the Individual Massachusetts Sheriffs' Offices," which mandates that sheriffs compile and submit quarterly reports detailing various data points for each individual committed to their facilities, including identifiers such as probation central file numbers, state identification numbers, race and ethnicity, and offense-based tracking numbers. The reports are to be submitted to key public safety officials and committees to ensure transparency and accountability in the management of correctional facilities. Additionally, the bill includes new definitions for critical data points and notes the limitations of sheriffs' offices in reporting certain data, such as case disposition and bail information, which are maintained by the Trial Court.

Furthermore, the bill proposes amendments to existing laws regarding the management and reporting of inmate admissions and releases in Bristol County, emphasizing the collection and categorization of demographic data, particularly race and ethnicity. It aims to enhance transparency and accountability in the correctional system by ensuring comprehensive data is maintained and accessible for review. The bill also introduces new legal language to improve tracking of earned time credits and other relevant data points that could impact an inmate's time served, thereby fostering a more equitable approach to corrections. Overall, the legislative effort reflects a commitment to reforming the justice system by promoting fairness and equity in the treatment of inmates and improving rehabilitation outcomes through structured programming and support services.
