The bill amends Massachusetts General Laws, specifically Chapter 126, Section 40, to enhance the reporting requirements for sheriffs regarding jail and house of correction populations. It mandates that sheriffs provide a comprehensive quarterly population report that includes detailed data for each committed individual, such as their probation central file number, state identification number, race and ethnicity, and offense-based tracking number. The reports must be aggregated and submitted to designated state officials without including any identifying information about individual inmates. Additionally, the bill introduces new definitions for key data points and clarifies that certain data, like case disposition and bail information, is sourced from the Trial Court rather than the Sheriffs' Offices.

Furthermore, the bill emphasizes the accurate recording of inmates' race and ethnicity, ensuring that this demographic information is consistently updated and maintained. It removes outdated legal language that may have previously obstructed effective data collection, thereby streamlining the process for better analysis of demographic trends within the correctional system. The legislation also outlines amendments related to inmate programming and rehabilitation services, highlighting the importance of educational and vocational training to reduce recidivism. It requires regular assessments of these programs to ensure equal access and effectiveness, ultimately aiming to foster a correctional environment that prioritizes rehabilitation and community safety.
