The bill amends Massachusetts General Laws, specifically Chapter 126, Section 40, to enhance the reporting requirements for jails and houses of correction, particularly focusing on the Suffolk County jail system. 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 containing various data points for each individual committed to their facilities. This includes probation central file numbers, state identification numbers, race and ethnicity, and offense-based tracking numbers, while ensuring that reports do not contain identifying information about individual inmates. The bill also defines critical data points and clarifies that certain data, such as case disposition and bail amounts, are managed by the Trial Court rather than the Sheriffs' Offices.

Additionally, the bill emphasizes the importance of tracking demographic information related to race and ethnicity among inmates, aiming to enhance transparency and accountability in the correctional system. It includes provisions for the collection of data on various racial and ethnic groups, ensuring that the information reflects the diverse population within the jail. While no specific legal language insertions or deletions are noted, the bill seeks to improve the overall management of the jail population and inform policy decisions by providing a clearer understanding of the demographics of those incarcerated. This focus on accurate data collection is intended to address potential disparities within the criminal justice system and promote equitable treatment for all individuals involved.
