Today, Connecticut's incarceration rates stand out internationally

graphic comparing the incarceration rates of the founding NATO members with the incarceration rates of the United States and the state of Connecticut . The incarceration rate of 664 per 100,000 for the United States and 394 for Connecticut  is much higher than any of the founding NATO members 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.
