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 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 need for collaboration with the Trial Court and the Executive Office of Public Safety and Security to improve reporting accuracy. Additionally, it proposes amendments to existing laws regarding the management of admissions and releases, including provisions for calculating jail credit and earned time, while addressing the handling of inmate classifications based on race and ethnicity. Furthermore, the bill introduces new legal language that specifies the inclusion of Hispanic/Latino and Not Hispanic/Latino categories in official documentation and data collection processes, aiming to enhance the accuracy of demographic data. It also seeks to delete outdated classifications that may not reflect current understandings of racial and ethnic identities, thereby streamlining reporting processes. The overall goal of the bill is to improve the efficiency and fairness of the correctional system, ensuring that data on inmate demographics and their respective sentences are accurately recorded and reported, ultimately promoting transparency and accountability within the system.
