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 sheriffs to 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 bill also includes new definitions for critical data points and emphasizes the limitations of sheriffs' offices in reporting certain data, as these originate from the Trial Court.

Additionally, the bill proposes amendments to existing laws regarding the management and reporting of inmate admissions and releases, focusing on the collection of demographic data related to race and ethnicity. It mandates the inclusion of detailed demographic information for individuals admitted to and released from jail, as well as tracking earned time and sentence credits for inmates, which may impact their release dates. The bill aims to streamline the legal framework by removing outdated provisions, thereby enhancing transparency and accountability in the correctional system and supporting efforts to address racial disparities. Overall, the proposed changes seek to improve the efficiency and fairness of the correctional system while promoting equitable treatment of all individuals within it.
