This study examined the impact that a six-month broken windows style policing crackdown on disorder had on residents of three California cities: Colton, Ontario and Redlands. The study investigated four questions:
- What is the impact of broken windows policing on fear of crime among residents of the targeted hot spots?
- What is the impact of broken windows policing on police legitimacy in the targeted hot spots?
- What is the impact of broken windows policing on reports of collective efficacy in the targeted hot spots?
- Is broken windows policing at hot spots effective in reducing both actual and perceived levels of disorder and crime in the targeted hot spots?
To answer these questions, a block randomized experimental design was employed to deliver a police intervention targeting disorder to 55 treatment street segments with an equal number of segments serving as controls.
Data were collected on the type and amount of crime before, during, and after implementation as well as interviews of residents before and after the crackdown in order to gauge their perception of its success.
Assessing the Link Between Foreclosure and Crime Rates: A Multi-level Analysis of Neighborhoods Across 29 Large United States Cities, 2007-2009 (ICPSR 34570)
These data are part of NACJD's Fast Track Release and are distributed as they were received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed.
The study integrated neighborhood-level data on robbery and burglary gathered from local police agencies across the United States, foreclosure data from RealtyTrac (a real estate information company), and a wide variety of social, economic, and demographic control variables from multiple sources. Using census tracts to approximate neighborhoods, the study regressed 2009 neighborhood robbery and burglary rates on foreclosure rates measured for 2007-2008 (a period during which foreclosure spiked dramatically in the nation), while accounting for 2007 robbery and burglary rates and other control variables that captured differences in social, economic, and demographic context across American neighborhoods and cities for this period. The analysis was based on more than 7,200 census tracts in over 60 large cities spread across 29 states. Core research questions were addressed with a series of multivariate multilevel and single-level regression models that accounted for the skewed nature of neighborhood crime patterns and the well-documented spatial dependence of crime.
The study contains one data file with 8,198 cases and 99 variables.

Census of Juveniles in Residential Placement, 2011 [United States] (ICPSR 36436)
The Census of Juveniles in Residential Placement (CJRP), conducted every other year, asks juvenile residential custody facilities in the United States to describe all youth assigned a bed in the facility on a specified reference date. In 2011, the reference date was Wednesday, October 26 (the last Wednesday in October).
Each record in the data provides information on a juvenile in a residential facility on the reference date, including information on placement (e.g. placing agency), the judicial process (e.g. court adjudication status), and demographics (e.g. age). Each record that provides information about a juvenile also includes information about institutional characteristics (e.g. facility type, use of locked doors or gates), treatment services, and population of the facility in which the juvenile was held. Therefore, CJRP data can be analyzed at the individual or facility level.
Some state and regional agencies provide CJRP data for more than one facility under their jurisdiction. The census was not sent to adult facilities or to facilities exclusively for drug or mental health treatment or for abused or neglected children.

This study examined arrestee DNA laws (laws that allowed testing of arrestees DNA pre-adjudication), their implementation in the field and their subsequent effects on agency operations as well as their success in aiding investigations in the 28 states that have these laws. The study investigated five specific questions:
- What states have passed legislation authorizing the collection of DNA from arrestees?
- How do the laws and policies regarding collecting DNA from arrestees differ by state?
- How have the courts ruled on these new laws?
- How have arrestee DNA laws been implemented in each state?
- What has been the impact of requiring DNA collection from arrestees on state crime laboratories and other involved agencies?
- What evidence is available to determine the effects of collecting DNA from arrestees on public safety or other criminal justice outcomes?
To answer these questions, researchers used a mixed methods data collection plan, including reviewing relevant statutes and case law, interviewing state and federal Combined DNA Index System (CODIS) laboratory staff and other forensic experts, and collecting descriptive data from state laboratories.
Collecting DNA from Juveniles in 30 U.S. States, 2009-2010 (ICPSR 31281)
This study examined the laws, policies, and practices related to juvenile DNA collection, as well as their implications for the juvenile and criminal justice systems. DNA evidence proved valuable in solving crimes, which motivated a concerted effort to expand the categories of offenders who provided DNA samples for analysis and inclusion in the Combined DNA Index System (CODIS), the Federal Bureau of Investigation (FBI)-operated national database.
State requirements for DNA collection, which initially focused on adult offenders convicted of sexual or violent offenses, expanded to include other categories of convicted felons, convicted misdemeanants, arrestees, and juveniles. In 30 states, certain categories of juveniles handled in the juvenile justice system must now provide DNA samples. The study was designed to explore the practice and implications of collecting DNA from juveniles and addressed the following questions:
- How have state agencies, juvenile justice agencies and state laboratories implemented juvenile DNA collection laws?
- What were the number and characteristics of juveniles with profiles included in CODIS?
- How have juvenile profiles in CODIS contributed to public safety or other justice outcomes?
- What improvements to policies and practices needed to be made?
To examine these questions, researchers at the Urban Institute: (1) systematically reviewed all state DNA statutes; (2) conducted semi-structured interviews with CODIS lab representatives in states that collect DNA from juveniles to understand how the laws were implemented; (3) collected and analyzed descriptive data provided by these labs on the volume and characteristics of juvenile profiles in CODIS; (4) conducted semi-structured interviews with juvenile and criminal justice stakeholders in five case study states; and (5) convened a meeting of federal officials and experts from the forensic and juvenile justice committees to explore the broader impacts of juvenile DNA collection.

Community Reporting Thresholds: Sharing Information with Authorities Concerning Terrorism and Targeted Violence, California and Illinois, 2021 (ICPSR 38318)
Parents, siblings, partners, and friends are often the first people to suspect a loved one is on the trajectory towards targeted violence or terrorism. These intimate bystanders are well positioned to facilitate prevention efforts if there are known and trusted reporting pathways to law enforcement or other resources. Little is known in the United States about the reporting processes for intimate bystanders to targeted violence or terrorism. This study is built on previous Australian and United Kingdom studies to understand the processes of intimate bystanders in the United States, in order to inform new, localized and contextually-sensitive understandings of and approaches to community reporting issues.
Qualitative-quantitative interviews were conducted from March 2021 to July 2021 virtually over Zoom with 123 community members living in California and Illinois. The researchers describe their perspectives on barriers, facilitators, and pathways. The study sought to enhance prior studies with a larger and more demographically-diverse sample. It included a focus on ISIS/Al-Qa'eda-inspired foreign-terrorism, White Power movement-inspired domestic terrorism, and--of particular relevance to the US---non-ideologically motivated targeted, workplace violence.
Community Restorative Healing Project, Los Angeles, California, 2017-2018 (ICPSR 37622)
The vision of the Community Restorative (CORE) Health Project was to increase awareness and availability of trauma-informed care and indigenous healing practices in the target communities for clients and families being served by the City of Los Angeles Mayor's Office of Gang Reduction and Youth Development (GRYD). Two agencies were contracted to provide either trauma-focused mental health treatment or training on indigenous healing practices to clients, families, and the community. A total of 115 individual or group therapy sessions were provided, 23 community based workshops on trauma-informed care or indigenous healing practices were offered, and 15 professional development events were attended by over 354 GRYD intervention workers or CORE staff.
Background information was collected during the initial stages of the GRYD program, and a youth's eligibility for GRYD services was determined. The Posttraumatic Screening Inventory was used to assess the presence of posttraumatic stress, exposure to a traumatic event, and whether participants should be referred for treatment. Youths were then exposed to the GRYD's Summer Night Lights program, which raised trauma awareness, taught coping strategies, and increased access to services.
Then the National Compadres Network was chosen to administer three training sessions on indigenous healing practices: La Cultura Cura, El Joven Noble, and Circle Keepers. Pre-test surveys collected demographics such as age, gender, ethnicity, and religiosity, as well as their expectations heading into training. Post-test surveys assessed how much information participants received, the usefulness of information, if training rationale made sense, and whether or not participants planned to use what they had learned. After training sessions were completed, researchers conducted 10 follow up interviews with services providers and leadership from CORE.
