Report California’s County Jails in the Era of Reform By Sonya Tafoya, Mia Bird, Ryken Grattet, Viet Nguyen Sep 26, 2016 California’s county jails have been profoundly affected by several reforms over the last decade. Most importantly, in 2011, public safety realignment shifted responsibility for large numbers of non-serious, non-violent, and non-sexual offenders from state prisons to county correctional systems. This lowered the state prison population—allowing prisons to prioritize beds for more serious offenders—but increased county jail populations. Three years later, Proposition 47 downgraded a range of drug and property offenses from potential felonies to misdemeanors. The reduced population pressure has allowed jails to prioritize beds for more serious drug and property offenders who are no longer eligible for prison. Despite the growing importance of jails, little is known about the basic characteristics of jail populations. In this report, we analyze state and local data on individuals moving through county correctional systems. Using data from 11 counties, we find that: Reforms altered the offender composition of the jail population, especially among those held on drug and property crimes. After three years under realignment, the number of drug and property offenders in jails increased by 55 percent and 40 percent, respectively. One year after the passage of Proposition 47, the number of drug and property offenders fell by 35 percent and 13 percent, respectively. Length of stay for felony drug and property offenders increased after realignment. For example, median time served for felony drug offenders released in October 2011 was 45 days, compared to 98 days for those released in October 2015. However, length of stay for people who served time for misdemeanors and felony crimes against persons has remained stable. Releases due to overcapacity rose under realignment and dropped after Proposition 47, when jail population pressure eased. The demographic composition of jails has largely remained stable. But the age distribution does show modest signs of change: the share of those ages 18–21 in jail has decreased slightly, as the share of those in their 30s has increased. As jail populations shift toward more serious drug and property offenders, counties and the state will need to consider how jail security and rehabilitative programs might be made more effective. While researchers and policymakers continue to examine the longer-term effects of realignment and Proposition 47, it is also important to keep in mind that the recent reprioritization of jail beds may have implications for crime and recidivism.
Report The Impact of Proposition 47 on Crime and Recidivism By Mia Bird, Magnus Lofstrom, Brandon Martin, Steven Raphael Jun 12, 2018 Passed by voters in November 2014, Proposition 47 brought broad and significant changes to California’s criminal justice system. Undertaken in the wake of public safety realignment in 2011, Proposition 47 reduced the penalties for certain lower-level drug and property offenses and represented a further step in prioritizing prison and jail space for higher-level offenders.
Report Capacity Challenges in California’s Jails By Magnus Lofstrom, Katherine Kramer Sep 27, 2012 In an effort widely known as "realignment,” California has given its counties enormous new responsibilities for corrections—including authority over many new types of felony offenders and parolees. Rather than go to state prison, these offenders now go to county jail or receive an alternative sanction. In the first few months of realignment, California’s jail population increased noticeably—but many jails were already facing capacity concerns. We find that some offenders who would have been incarcerated prior to realignment are now either not locked up or are not spending as much time in jail. Going forward, counties will need to consider a wide variety of approaches for handling their capacity concerns and their expanded offender populations.
blog post A Closer Look at Early Jail Releases By Magnus Lofstrom, Brandon Martin Sep 17, 2014 Almost three years after California’s public safety realignment took effect, county sheriffs have few options for handling jail populations that are approaching historical highs reached in 2007.
blog post Proposition 47 and Crime By Magnus Lofstrom, Brandon Martin Oct 28, 2015 Reports of increases in violent crime in some areas have raised concerns. But it would be premature to blame Proposition 47.
blog post County Jails House Fewer Inmates, but Over Half Face Mental Health Issues By Magnus Lofstrom, Brandon Martin Oct 25, 2023 While the number of people in California's county jails has declined markedly over the last decade, the share of inmates with mental health needs has grown to more than half of the total jail population.
