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 a comprehensive quarterly population report from individual Massachusetts Sheriffs' Offices, which must include detailed inmate data such as probation central file number, state identification number, race and ethnicity, offense-based tracking number, and type of release, while ensuring that no identifying information about individual inmates is disclosed. The bill also introduces new definitions for key terms related to inmate tracking and clarifies that certain data points, like case disposition and bail information, are managed by the Trial Court rather than the Sheriffs' Offices.

Additionally, the bill proposes amendments to improve the management of pre-trial and sentenced individuals in the Plymouth area, emphasizing the tracking of admissions and releases, including demographic details and the duration of sentences. It introduces new legal language to enhance record-keeping of individuals' time in custody, including earned jail credit and specific admission and release dates. The bill aims to promote transparency and accountability within the judicial process, ensuring equitable treatment across different racial and ethnic groups, while also enhancing educational and rehabilitative opportunities for inmates to reduce recidivism rates. Regular reporting on program outcomes is mandated to assess the effectiveness of these initiatives.
