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.

Collecting DNA at Arrest: Policies, Practices, and Implications, in 28 States, 2005-2012 (ICPSR 34682)
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.
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.

Common Operational Picture Technology in Law Enforcement: Three Case Studies, Baton Rouge, Louisiana, Camden County, New Jersey, Chicago, Illinois, 2015-2019 (ICPSR 37582)
The use of common operational picture (COP) technology can give law enforcement and its public safety response partners the capacity to develop a shared situational awareness to support effective and timely decision-making. These technologies collate and display information relevant for situational awareness (e.g., the location and what is known about a crime incident, the location and operational status of an agency's patrol units, the duty status of officers).
CNA conducted a mixed-methods study including a technical review of COP technologies and their capacities and a set of case studies intended to produce narratives of the COP technology adoption process as well as lessons learned and best practices regarding implementation and use of COP technologies.
This study involved four phases over two years: (1) preparation and technology review, (2) qualitative case studies, (3) analysis, and (4) development and dissemination of results. This study produced a market review report describing the results from the technical review, including common technical characteristics and logistical requirements associated with COP technologies and a case study report of law enforcement agencies' adoption and use of COP technologies. This study provides guidance and lessons learned to agencies interested in implementing or revising their use of COP technology. Agencies will be able to identify how they can improve their information sharing and situational awareness capabilities using COP technology, and will be able to refer to the processes used by other, model agencies when undertaking the implementation of COP technology.
Community Crime Prevention and Intimate Violence in Chicago, 1995-1998 (ICPSR 3437)
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.
Comparative Evaluation of Court-Based Responses to Offenders with Mental Illnesses, Cook County, Illinois, 1953-2014 (ICPSR 35650)
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.
This study was designed to provide a mixed methods comparative evaluation of three established court-based programs that serve offenders with serious mental illness (SMI). These programs were selected in response to criticism of similar research for studying young programs that are still in development, employing short follow up periods that are unable to indicate sustained effectiveness, and utilizing less than ideal comparison conditions. The study was conducted in Cook County, Illinois, and data were collected from three distinct court-based programs: the Cook County Felony Mental Health Court (MHC) which serves individuals with SMI who have been arrested for nonviolent felonies, the Specialized Mental Health Probation Unit which involves specially trained probation officers who supervise a reduced caseload of probationers diagnosed with SMI, and the Cook County Adult Probation Department which has an active caseload of approximately 25,000 probationers, a portion of whom have SMI. Probation officer interviews were coded for themes regarding beliefs about the relationship between mental illness and crime, views on the purpose of their program, and approaches used with probationers with SMI. The coding of probationer interviews focused on experiences related to having SMI and being on probation, including: the extent to which probation was involved with mental health treatment; development of awareness of mental health issues; evaluations of the programs based on subjective experiences; and the relationship dynamics between probationers and staff.
The collection includes 3 Stata data files: DRI-R_data_for_NACJD_041315.dta with 98 cases and 61 variables, Epperson_NIJ_Quantitative_Data_for_NACJD_041315.dta with 25203 cases and 49 variables, and incarceration_data_061515.dta with 676 cases and 4 variables. The qualitative data are not available as part of this data collection at this time.
