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.
blog post Crime Rates Down, But Not Everywhere By Magnus Lofstrom Nov 11, 2014 Most of California’s counties saw lower crime rates in 2013, according to the latest data. Violent crime dropped in 41 out of the 58 counties, and property crime dropped in 37 counties.
Report Realignment, Incarceration, and Crime Trends in California By Steven Raphael, Magnus Lofstrom May 19, 2015 When California’s historic public safety realignment was implemented in October 2011, many were concerned about the impact it would have on crime rates. In a 2013 report, we found that realignment did not increase violent crime in its first year, but that it did lead to an increase in auto thefts. In this report, we assess whether these trends continued beyond realignment’s first year. We find that both the prison and jail populations increased slightly since 2012, which means that the number of offenders on the street did not rise from the 18,000 during realignment’s first year. This is likely to change with the implementation of Proposition 47, which further reduces California’s reliance on incarceration. Our analysis of updated state-level crime data from the FBI confirms our previous findings. Violent crime rates remain unaffected by realignment, and although California’s property crime rate decreased in 2013, it did not drop more than in comparable states—so the auto theft gap that opened up in 2012 has not closed. Research indicates that further reductions in incarceration may have a greater effect on crime trends; the state needs to implement effective crime prevention strategies—and it can learn about alternatives to incarceration successfully implemented by the counties as well as other states.
blog post A Large Proportion of Crime Goes Unsolved in California By Magnus Lofstrom May 11, 2023 California’s clearance rates—the shares of reported crimes for which police make an arrest and refer the arrestee to prosecution—are better than those nationwide. Still, statewide less than half of violent crimes and only one in ten property crimes are cleared.
Report Are Younger Generations Committing Less Crime? By Magnus Lofstrom, Brandon Martin, Deepak Premkumar Sep 27, 2023 Among Californians born in 1993 and later, criminal offending has fallen 20 to 25 percent compared to previous generations. This shift in longstanding trends is a driving factor behind the overall decline in crime over the last decades and has several broader implications for the criminal justice system.
blog post After Decreases in 2020, Both Property and Violent Crimes Are Up in 2021 By Magnus Lofstrom, Brandon Martin Dec 14, 2021 Preliminary data from four major California cities—Los Angeles, Oakland, San Diego, and San Francisco—show that property and violent crime numbers have increased and are now similar to pre-pandemic levels.
blog post Next Steps for Proposition 57 By Magnus Lofstrom, Brandon Martin Nov 9, 2016 The passage of Proposition 57 brings significant changes to California’s criminal justice system.
