The ACLU of Massachusetts develops interactive tools for users to learn more about and explore government data – including readily available data, data received via public records requests, and data resulting from litigation.

Tracking COVID-19 in Massachusetts Prisons & Jails

Track testing, positive cases, and releases in prisons and jail during the COVID-19 pandemic, as documented in reports made by Massachusetts prisons and jails to the Supreme Judicial Court (SJC). The data are supplied by county sheriffs and the Massachusetts Department of Correction (DOC) pursuant to the Court’s decision in Committee for Public Counsel Services (CPCS) v. Chief Justice of the Trial Court, SJC-12926.


Mapping Alleged Police Violence & Misconduct

Massachusetts is not immune to police violence and misconduct – and we must demand change. Our map documents incidents of alleged police violence and alleged misconduct that occurred in Massachusetts since 2000, as one portion of our extension Week of Action in support of strong police reform in the Commonwealth.


Tracking Boston Police Incidents

Track the activity of the Boston Police Department over time, including the frequency and location of specific incident types. Police incident reports are publicly available data hosted on Analyze Boston. The reports posted there go back to June 2015, and are (usually) updated daily by the Boston Police.


Police in Politics

Police reform and budgeting has become a high priority in Boston, across the Commonwealth, and nationally. However, engagement by police staff and their unions in state and local politics often acts as an obstacle to meaningful reform. Trace police-related donations to Mayor Walsh and to the Boston City Council from 2010 to 2020 (up to and including the most recent quarter filing), using data from the Massachusetts Office of Campaign and Political Finance.


Mapping Internet Access in Massachusetts

Using data from the Census’ American Community Survey, we map internet and computer access across the Commonwealth. The data show that many urban and rural areas in Massachusetts are “internet deserts”, where access is severely limited.
