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. This includes 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, promoting transparency and accountability in the management of inmate populations.

Additionally, the bill emphasizes the importance of tracking demographic data, particularly focusing on race and ethnicity, to identify any disparities in treatment within the criminal justice system. It introduces new legal language that modernizes the classification of individuals as "pre-trial" or "sentenced," while removing outdated terminology. The bill also highlights the significance of educational and rehabilitative programs for individuals in custody, aiming to reduce recidivism rates and improve post-release outcomes. Overall, the proposed changes reflect a commitment to reforming the criminal justice system in Barnstable, ensuring equity and support for individuals navigating the legal process.
