The bill amends Massachusetts General Laws, specifically Chapter 126, Section 40, to enhance the reporting requirements for jails and houses of correction. It introduces a new section titled "Overview of Quarterly Population Report for the Individual Massachusetts Sheriffs' Offices," which mandates sheriffs to compile and submit quarterly reports detailing various data points for each individual committed to their facilities, including probation central file number, state identification number, race and ethnicity, and type of release. These reports will be submitted to key public safety officials without any identifying information about individual inmates. The bill also 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 managed by the Trial Court.

Additionally, the bill proposes amendments to improve the management and reporting of inmate admissions and releases in Barnstable, focusing on the collection of demographic data to ensure accurate representation of the inmate population. It emphasizes transparency and accountability in the correctional system by requiring detailed reporting on booking and release dates, as well as tracking earned credits and sentence adjustments for inmates. The proposed changes aim to enhance the overall management of inmate data, improve the effectiveness of rehabilitation programs, and promote fair treatment within the correctional system, ultimately contributing to lower recidivism rates.
