Report Racial Disparities in Traffic Stops By Magnus Lofstrom, Joseph Hayes, Brandon Martin, Deepak Premkumar Oct 10, 2022 Traffic stops have emerged as a key driver of racial disparities in law enforcement and an area of potential reform. Our new report examines whether certain types of traffic stops could be enforced in alternative ways that reduce racial disparities and risks to officers and civilians without jeopardizing public safety.
Report Racial Disparities in Law Enforcement Stops By Magnus Lofstrom, Joseph Hayes, Brandon Martin, Deepak Premkumar Oct 13, 2021 Recent debate over police reforms has centered on how law enforcement engages with people of color, prompted by continuing concerns over racial inequities in criminal justice. In our analysis of data for nearly 4 million stops, we examine how interactions—ranging from search to use of force—differ for Black and white people, while considering factors such as stop context and law enforcement agency.
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 Public Safety Realignment: Impacts So Far By Magnus Lofstrom, Brandon Martin Sep 28, 2015 Prompted by a federal court order to reduce prison overcrowding, California’s 2011 historic public safety realignment shifted many correctional responsibilities for lower-level felons from the state to counties. The reform was premised on the idea that locals can do a better job, and it was hoped that incarceration rates and corrections costs would fall. At the same time, critics predicted crime would rise. Four years since its implementation, realignment has made several important impacts: Realignment significantly reduced the prison population, but the state did not reach the court-mandated population target until after the passage of Proposition 47 in November 2014, which reduced penalties for many property and drug offenses. The reform challenged county jails and probation departments by making them responsible for a greater number of offenders with a broader range of backgrounds and needs. The county jail population did not rise nearly as much as the prison population fell, reducing the total number of people incarcerated in California. Realignment did not increase violent crime, but auto thefts rose. Research so far shows no dramatic change in recidivism rates. State corrections spending remains high, but there is reason to believe expenditures could drop in the future. Realignment has largely been successful, but the state and county correctional systems face significant challenges. The state needs to regain control of prison medical care, which is now in the hands of a federal receiver. And the state and counties together must make progress in reducing stubbornly high recidivism rates.
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.
Report Alternatives to Incarceration in California By Ryken Grattet, Brandon Martin Apr 17, 2015 Three-plus years after implementing a major realignment of its public safety systems, California continues to face pressure to reduce both its prison and jail populations. California relied on some alternatives to custody-based punishment before realignment but it has been expanding its use of others. Current research on the effects of incarceration and its alternatives offers a general endorsement of the idea that increasing reliance on community-based alternatives is not likely to result in large increases in crime and recidivism. The evidence suggests that the effectiveness of both incarceration and community-based supervision depends on a number of factors, including the rate of incarceration in a given community, the offender characteristics, and the nature of the response to violations during and after supervision. Finally, intensive data collection on county implementation efforts can help the state identify the community-based strategies that produce the best outcomes.
blog post How California Reduced Its Prison Population By Magnus Lofstrom, Brandon Martin Feb 6, 2015 The state has reduced its prison population by the court-mandated target, but not—as reform proponents hoped—by a major reduction in costly prison incarceration.
blog post Realignment: Progress and Challenges By Magnus Lofstrom Jul 21, 2014 Now that realignment is approaching the three-year mark, has the reform delivered? In some important ways, yes, it has. But a fundamental issue remains.
Report Key Factors in California’s Jail Construction Needs By Magnus Lofstrom, Brandon Martin May 7, 2014 Now that California has shifted responsibility for many criminal offenders to the counties, county jail systems face greater capacity challenges. This report highlights two important factors in addressing jail capacity constraints: aging jail facilities and long-term needs. We show that a number of facilities are old and likely in need of costly updates or replacement and that growth in the state’s population is likely to exert significant pressure on the county jail system. Our analysis suggests that a thoughtful combination of further jail construction and decreased reliance on incarceration is needed, given the magnitude of the current and future jail needs.
