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 that sheriffs record and report comprehensive data for each individual committed, including identifiers such as probation central file number, state identification number, race and ethnicity, and offense-based tracking number. Sheriffs are also required to compile this data into a quarterly report submitted to various state officials, ensuring that no identifying information about individual inmates is included. The bill introduces new legal language defining key data points and highlights limitations in reporting certain data, such as case disposition and bail information, which are outside the sheriffs' control.

Additionally, the bill proposes amendments to existing laws concerning the management and reporting of inmate admissions and releases, emphasizing the collection of demographic data to ensure accurate representation of the inmate population. It includes provisions for tracking various details such as race, ethnicity, length of stay, booking dates, and earned time credits, aiming to enhance transparency and accountability within the correctional system. The legislation also seeks to streamline operations by clarifying processes involved in admissions and releases while removing outdated legal language. Overall, the bill reflects a commitment to equitable treatment and informed decision-making based on accurate demographic data within the justice system.
