The bill amends Massachusetts General Laws, specifically Chapter 126, Section 40, to enhance the reporting requirements for jails and houses of correction in Hampden County. 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 inmate, including probation central file number, state identification number, race and ethnicity, and offense-based tracking number, while ensuring that no identifying information about individual inmates is included. The bill also establishes new definitions for critical data points and highlights limitations in reporting specific data, such as case disposition and bail amounts, which are outside the control of the Sheriffs' Offices.

Additionally, the bill proposes new legal language to improve the classification and reporting of individuals based on race and ethnicity, ensuring accurate documentation that reflects the diversity of the population. It aims to streamline the reporting process by removing outdated legal language that may hinder effective data collection and analysis. The proposed changes are designed to enhance transparency and accountability in the correctional system, improve the accuracy of demographic data, and ultimately address disparities in the treatment of different racial and ethnic groups within the justice system. Overall, the bill emphasizes the importance of comprehensive data collection and rehabilitation programs to support successful reintegration into society.
