The bill introduces new legal language to enhance the reporting requirements for the Massachusetts Sheriffs' Offices concerning the population of jails and houses of correction. It mandates that sheriffs collect and report specific data points for each individual committed, including probation central file numbers, state identification numbers, race and ethnicity, and offense-based tracking numbers. Additionally, aggregate data must be compiled into a quarterly report submitted to public safety and legislative officials, ensuring that no identifying information about individual inmates is included. The bill also defines key data points and notes the limitations of the Sheriffs' Offices in reporting certain data, such as case disposition and bail information, which are maintained by the Trial Court.

Furthermore, the bill proposes amendments to existing laws regarding the management and reporting of inmate data within the Middlesex County correctional facilities. It emphasizes the collection of demographic information, including race and ethnicity, and mandates the tracking of inmates' length of stay, booking and release dates, and earned time credits. The bill aims to enhance transparency and accountability in the correctional system by requiring detailed reporting on inmate demographics and program participation. It also seeks to streamline data collection by mandating electronic submission of all relevant information, thereby improving efficiency and promoting equitable treatment of all individuals within the correctional system.
