Today, Massachusetts’s incarceration rates stand out internationally

In the U.S., incarceration extends beyond prisons and local jails to include other systems of confinement. The U.S. and state incarceration rates in this graph include people held by these other parts of the justice system, so they may be slightly higher than the commonly reported incarceration rates that only include prisons and jails. Details on the data are available in States of Incarceration: The Global Context. We also have a version of this graph focusing on the incarceration of women.

People of color are overrepresented in prisons and jails

See also our detailed graphs about Whites, Hispanics, and Blacks in Massachusetts prisons and jails.

Massachusetts's criminal justice system is more than just its prisons and jails
