Governor Brown has proposed a ballot measure—the Public Safety and Rehabilitation Act—that could significantly alter sentencing in California. If it qualifies for the ballot—which seems likely—and is approved by voters in November, the measure would allow non-violent felons who have earned enough credits for good behavior to spend less time in state prison. It would also shift the power to determine whether juveniles should be tried as adults from prosecutors to judges. The measure follows the path of decreased reliance on incarceration that California has been on since 2009.
Motivated primarily by a federal court’s 2009 mandate to improve health care and reduce overcrowding in the state’s prison system, California has implemented a number of measures that have considerably reduced the prison population. Since reaching a historic high in 2006, the prison population has dropped by 45,000, a decrease of about 26 percent, and the state’s overall incarceration rate is down to levels not seen since the early 1990s.
Although a number of policies have contributed to this decline, it is largely attributable to two recent major reforms: the 2011 Public Safety Realignment Act, or AB 109, which shifted responsibility for many non-serious, non-violent, and non-sexual offenders to county jail and probation systems; and Proposition 47, which reclassified some drug and property felonies as misdemeanors. Since January 2015, two months after voters approved Prop 47, the prison population has remained below the court-mandated target. That is good news for the state. However, the institutional population is only about 1.1 percent, or 900 inmates, below the target. Given this slim margin—and given the fact that the state still needs to show that it is providing adequate health care—the pressure is still on.
Californians appear to be supportive of lessening penalties for crime and downsizing state prisons. Recent criminal justice initiatives, such as Proposition 36 in 2012 (which revised California’s three-strikes law) and Proposition 47 in 2014, passed by rather wide margins—close to 70 percent and around 60 percent respectively.
Voters may well be inclined to see reductions in spending on prisons, and with good reason. California’s corrections budget continues to grow, with the governor requesting $10.6 billion from the General Fund for 2016–17—a historic high. This amount does not include more than $1 billion annually that the state transfers to counties to implement realignment. For 2016–17, the state is projecting the cost of the prison system to be almost $70,000 per prisoner. A significant reduction in the prison population could finally allow the state to stop the use of out-of-state contract beds and possibly close a state prison. These actions could potentially lead to hundreds of millions of dollars in annual savings. Without further reductions in the prison population, it will be difficult for the state to stop using contract beds and remain below the court-ordered population cap.
Finally, it should be noted that, unlike realignment and Propositions 36 and 47, which implemented changes based on the kind of offenses committed, this measure focuses mainly on the behavior of the offenders. After they earn enough credits for good behavior and achievements in education and rehabilitation, non-violent prison inmates can be paroled and released early. If this incentive is accompanied by effective educational and rehabilitative programs, it could reduce recidivism. More broadly, this measure, combined with the redirection of spending toward cost-effective crime preventive strategies, could help California use its corrections resources more wisely.

Proposition 47 helped bring down the prison population by about 8,000 inmates, below the mandated target of 137.5 percent of design capacity (the number of inmates that facilities were designed to house). The target was set by a federal court in 2009 in the wake of lawsuits over prison conditions; at the time, it meant a reduction of almost 40,000 prisoners. The prison population has remained below the target since January 2015. This is a key requirement for the state to regain control of prison health care, which is currently overseen by a court-appointed receiver. The total prison population has dropped by slightly more than 45,000 inmates since it peaked in 2006.
As we noted above, reports of increased crime in a number of cities and counties in 2015 have fueled concerns about the impact of these population reductions. Between January and August, violent crime in Sacramento was up by 24 percent compared to the same months in 2014. In Riverside County, violent crime was up almost 11 percent in the first six months of 2015. In the City of Los Angeles, it was up almost 21 percent in the same time period.

As of August 2015, the total prison population had dropped by almost 45,000 inmates from its 2006 peak. The majority (about 55%) of the decline was a result of realignment, which was implemented in October 2011 in response to a court order to improve prison conditions by reducing overcrowding. However, it took the passage of Proposition 47 last November—which reclassified a number of felony drug and property offenses as misdemeanors—and building and renting additional prison beds to reach the court-ordered population target of 137.5 percent of design capacity. The prison population has declined by almost 7,700 since November and has remained below the mandated target since January 2015. This is a key requirement for the state to regain control over prison health care—currently, a court-appointed receiver oversees health care in the system.
Although we can see that prison population numbers have dropped in each of the nine months since Proposition 47 passed, we need to be more cautious about the measure’s impact on jail population numbers because we only have jail data for the first two months. Also, counties have been working to implement and refine new jail policies and procedures, and these may be having an impact on jail populations. For instance, data through March 2015 for Los Angeles County show that the jail population dipped below 16,000 inmates in December (down from more than 18,000 in October), but rose above 17,000 in January and stayed above 17,000 through March. This increase is related to the sheriff requiring that inmates serve a larger percentage of their sentences before release. We may see similar developments in other counties. Nonetheless, even in Los Angeles there was a noticeable drop in the jail population compared to months before passage of Proposition 47.


Since reaching its peak in 2006 of about 163,000, the institutional prison population has dropped dramatically, by slightly more than 49,000. The court order mandated that inmate population be reduced to 137.5 percent of design capacity, or the number of inmates the facilities were intended to house.
California has indeed seen a significant decrease in the reliance on incarceration over the last decade through policies like SB 678 and realignment, as well as initiatives like 2012 Proposition 36 (which revised California’s “Three Strikes” law) and Proposition 47. Our total incarceration rate has dropped from about 702 per 100,000 residents in 2006 to about 568. Unfortunately this is not reflected in the state’s expenditures. In fact, spending on corrections is now at a historic high. A look at corrections spending going back to the 1970s shows a long-term increase. In the current budget year, the state is spending more than $12 billion on corrections. In other words, meeting the federally mandated target does not mean that California has solved its incarceration problem.
