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 overview section for the Quarterly Population Report, mandating that sheriffs record and report 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. These reports must be submitted quarterly to designated officials without including any identifying information about individual inmates. The bill also establishes new definitions for key terms related to the data being reported and notes that certain required data points, such as case disposition and bail information, are not owned by the Sheriffs' Offices and originate from the Trial Court.

Additionally, the bill emphasizes the importance of accurate data collection to enhance transparency and accountability within the correctional system, ensuring equitable treatment of inmates. It outlines procedures for the collection and reporting of demographic data, including race and ethnicity, and mandates standardized practices for consistency and reliability. Provisions for regular audits to assess compliance with these new requirements are also included, with the overall goal of fostering a more inclusive and fair correctional environment by addressing disparities and promoting better outcomes for all inmates.
