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 mandates a quarterly population report that includes an "Overview of Quarterly Population Report for the Individual Massachusetts Sheriffs' Offices," which must compile aggregate data on the jail population without identifying individual inmates. This report is to be submitted to various state officials, including the secretary of public safety and security and the chairs of relevant legislative committees. Additionally, the bill introduces "Data Definitions & Disclaimer" to clarify terms used in the reports and notes an "Important Data Note" regarding data points that are not maintained by the Sheriffs' Offices but originate from the Trial Court.

Furthermore, the bill proposes amendments to existing laws concerning the management of pre-trial and sentenced individuals in Bristol, emphasizing the tracking of demographic data related to race and ethnicity. It outlines the admission and release processes for individuals, detailing their booking dates, sentencing durations, and the nature of their charges. The bill aims to enhance transparency and accountability within the judicial system by ensuring accurate data collection and reporting, which may help identify disparities in treatment based on race or ethnicity. It also introduces new legal language to clarify the roles of various stakeholders in the judicial process while removing outdated language to streamline the application of these provisions.
