Additionally, the number of people impacted by county and city jails in California is much larger than the graph above would suggest, because people cycle through local jails relatively quickly. Each year, at least 368,000 different people are booked into local jails in California.

Today, California’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 California. The incarceration rate of 698 per 100,000 for the United States and 581 for California is much higher than any of the founding NATO membersIn 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.
