CDCR owns and operates
34 prisons throughout the state and operates
1 prison leased from a private company.
The California Department of Corrections and Rehabilitation had a $15.8B budget for the 2019-2020 fiscal year, which was 7.4% of the state budget ,
and $13.6 billion ($13.3 billion General Fund and $347 million other funds) for CDCR in 2021-22. The state's prison medical care system has been in receivership since 2006, when a federal court ruled in
Plata v. Brown that the state failed to provide a constitutional level of medical care to its prisoners. Since 2009, the state has been under
court order to reduce prison overcrowding to no higher than 137.5% of total design capacity.

Major court cases and policy changes
Over the past 4 decades, the California prison system has been substantially shaped by a set of legislative initiatives that caused a large increase in the prison population, which resulted in severe prison overcrowding and unconstitutional living conditions. Those conditions led to a set of court cases that mandated a reduction in overcrowding and changes to prison services, which resulted in a number of legislative initiatives to reduce overcrowding and improve conditions.
Prison population and overcrowding
California's prison population grew dramatically after the passage of the
Uniform Determinate Sentencing Act of 1976 The Uniform Determinate Sentencing Act of 1976 was a bill signed into law by Governor Jerry Brown to changes sentencing requirements in the California Penal Code. The act converted most sentences from an "indeterminate" sentence length at the discre ...
. The introduction of determinate sentencing and subsequent increases in prison sentence lengths was the largest driver in a nearly 900% increase in California's prison population over the next 3 decades.
In 1994, as part of a wave of "tough on crime" laws passed across the country, California passed a
Three Strikes Law
In the United States, habitual offender laws (commonly referred to as three-strikes laws) have been implemented since at least 1952, and are part of the United States Justice Department's Anti-Violence Strategy. These laws require a person who i ...
that required a doubled sentence for any felony if the person convicted had a prior "serious or violent" felony conviction. It also required a mandatory 25-year-to-life sentence for any felony if the person convicted had two prior "serious or violent" felony convictions. 'Three Strikes' was one of the largest drivers of California's increasing prison population over the next 2 decades. The highest recorded CDCR daily prison population was on October 20, 2006, with 173,643 people under custody.

In response to this population growth, between 1984 and 2005 California built 21 of the 35 prisons that CDCR currently operates in the state (see

for full details). Despite this construction, most of the prisons continued to be overcrowded. In 1995, the court ruled in federal class action civil rights lawsuit
Plata v. Brown that CDCR failed to provide a constitutional level of medical care to its prisoners and ordered the state's prison medical care system be put into
receivership
In law, receivership is a situation in which an institution or enterprise is held by a receiver – a person "placed in the custodial responsibility for the property of others, including tangible and intangible assets and rights" – especia ...
. The receivership started in 2006 and is still active. After the state's prison population peaked in 2006, a three-judge panel was convened in
Plata and Coleman. This panel ordered the state to reduce its prison population to 137.5% of prison design capacity. The court order is still active.
Since that court order, the state has taken several steps to reduce prison overcrowding. In 2011, California passed
Public Safety Realignment, which altered sentencing and supervision guidelines to shift responsibility for some prisoners to counties. Under Realignment, people with convictions for "non-serious, non-violent, non-sex" crimes serve their sentences in county jails and are under county community supervision upon release. CDCR also contracted with private companies to incarcerate thousands of people in private facilities in other states.
Other legislative changes to reduce prison overcrowding include
2014 California Proposition 47
Proposition 47, also known by its ballot title Criminal Sentences. Misdemeanor Penalties. Initiative Statute, was a referendum passed by voters in the state of California on November 4, 2014. The measure was also referred to by its supporters a ...

to release people convicted of "non-violent" crimes once they served the full sentence for their primary offense. Prop 57 also required CDCR to develop uniform parole credits for good behavior and rehabilitative achievements, to incentivize rehabilitation. While prison populations have been declining since their peak in 2006, as of April 2020, 32 of California's 35 state-run prisons have incarcerated populations above their design capacities, and 10 prisons have incarcerated populations greater than the 137.5% limit from the
Plata and Coleman court order.

State corrections and rehabilitation costs

Since the 2007–2008 fiscal year (the oldest year with enacted budget records maintained online by the state), Corrections and Rehabilitation has been between 6.3% and 7.8% of the California state budget. In the 2019-2020 fiscal year, Corrections and Rehabilitation had a state budget of $15,788,581,000, or 7.4% of the total state budget, and was the 4th largest agency area budget.
The majority of that budget goes towards personnel costs, with an estimated 57,653 positions funded for the 2019-2020 fiscal year. CDCR funding is organized into the following programs:
* Adult Corrections and Rehabilitation Operations
* Adult Health Care Services
* Adult Rehabilitative Programs
* Board of Parole Hearings
* Corrections and Rehabilitation Administration
* Department of Justice Legal Services
* Juvenile Services
* Parole Operations
* Peace Office Selection and Employee Development
The costs to run prisons are substantially subsidized by the use of incarcerated labor. Incarcerated workers do meal preparation, laundry, janitorial services, building maintenance, and other activities necessary for the day-to-day operations of a prison. Incarcerated workers are paid between $.08 and $.37 per hour for their labor.
Demographics and statistics
Gender
Prior to the passage of SB 132, CDCR divided the in-custody population into men and women. Men made up 95.5% of the in-custody population in 2018.
Prisons facilities are designed for and run based on a specific gender/gender identity. In 2019, the California state legislature passed SB 132, "The Transgender Respect, Agency, and Dignity Act", which will require that CDCR "house the person in a correctional facility designated for men or women based on the individual’s preference" starting in 2021.

Sentences
As of the most recent CDCR "Offender Data Points" report,
the California state prison population breaks down by sentence type as follows:
Per the report, "Others" includes "those with commitment information not yet entered, those sentenced to prison for diagnostic evaluation, and boarders from other jurisdictions".
While California has a moratorium on the death penalty, it has the largest condemned population of any state in the United States.
Death in prison
While the last
execution in California was in 2006, incarcerated people die in California prisons regularly. The most common cause of death in prison is "natural causes" (old age, chronic illness, or disease), followed by justifiable homicide at the hands of a law enforcement officer and then suicide.
There were 9,909 deaths in CDCR custody from 2005 - 2018:
Most suicides are via hanging. Most accidental deaths are from drug overdoses.
Prison conditions
The state's prison medical care system has been in receivership since 2006, when a federal court ruled in
Plata v. Brown that the state failed to provide a constitutional level of medical care to its prisoners. Since 2009, the state has been under
court order to reduce prison overcrowding to no higher than 137.5% of total design capacity. "The state spends millions of dollars each year in class-action litigation costs alone", often related to overcrowding or inadequate health care. In 2012, in response to multiple long-standing class-action lawsuits, as well as budget concerns and continuing overcrowding after
Public Safety Realignment, CDCR published "The Future of California Corrections: A Blueprint to Save Billions of Dollars, End Federal Court Oversight, and Improve the Prison System", which articulated a strategy to improve rehabilitative programming, health care, housing, and parole operations.
