Controlling Victimization in Schools: Effective Discipline and Control Strategies in a County in Ohio, 1994 (ICPSR 2587)
Released/updated on: 2006-03-30
Geographic coverage: United States, Ohio
The purpose of this study was to gather evidence on the relationship between discipline and the control of victimization in schools and to investigate the effectiveness of humanistic versus coercive disciplinary measures. Survey data were obtained from students, teachers, and principals in each of the 44 junior and senior high schools in a county in Ohio that agreed to participate in the study. The data represent roughly a six-month time frame. Students in grades 7 through 12 were anonymously surveyed in February 1994. The Student Survey (Part 1) was randomly distributed to approximately half of the students in all classrooms in each school. The other half of the students received a different survey that focused on drug use among students (not available with this collection). The teacher (Part 2) and principal (Part 3) surveys were completed at the same time as the student survey. The principal survey included both closed-ended and open-ended questions, while all questions on the student and teacher surveys were closed-ended, with a finite set of answers from which to choose. The three questionnaires were designed to gather respondent demographics, perceptions about school discipline and control, information about weapons and gangs in the school, and perceptions about school crime, including personal victimization and responses to victimization. All three surveys asked whether the school had a student court and, if so, what sanctions could be imposed by the student court for various forms of student misconduct. The student survey and teacher surveys also asked about the availability at school of various controlled drugs. The student survey elicited information about the student's fear of crime in the school and on the way to and from school, avoidance behaviors, and possession of weapons for protection. Data were also obtained from the principals on each school's suspension/expulsion rate, the number and type of security guards and/or devices used within the school, and other school safety measures. In addition to the surveys, census data were acquired for a one-quarter-mile radius around each participating school's campus, providing population demographics, educational attainment, employment status, marital status, income levels, and area housing information. Also, arrest statistics for six separate crimes (personal crime, property crime, simple assault, disorderly conduct, drug/alcohol offenses, and weapons offenses) for the reporting district in which each school was located were obtained from local police departments. Finally, the quality of the immediate neighborhood was assessed by means of a "windshield" survey in which the researchers conducted a visual inventory of various neighborhood characteristics: type and quality of housing in the area, types of businesses, presence of graffiti and gang graffiti, number of abandoned cars, and the number and perceived age of pedestrians and people loitering in the area. These contextual data are also contained in Part 3.

Released/updated on: 2023-01-31
Geographic coverage: Chicago, Illinois, Louisiana, New Orleans, Maryland
Time period: 2010-01-01--2016-01-01
The International Association of Chiefs of Police (IACP), collaborating with research partners, conducted a 48-month, two-phase research initiative to enhance their understanding of how firearms move from legal purchase to involvement with a crime. Phase 1 used trace data from Chicago, New Orleans, and Prince Georges County, MD to establish the path of firearms from purchase to usage in a crime. Interviews of the first legal purchaser and incarcerated inmates who committed a crime of violence in New Orleans and Prince Georges County were conducted to seek an understanding of how firearms enter the unregulated market. Phase 2 examined the use of the Group Violence Reduction Strategy (GVRS) in New Orleans as a strategy to reduce gang and gun-related homicides. Overall violence patterns in New Orleans were examined from 2010-2016.

Homicides in Chicago, 1965-1995 (ICPSR 6399)
Released/updated on: 2005-07-06
Geographic coverage: United States, Chicago, Illinois
Time period: 1965-01-01--1995-01-01
These datasets contain information on every homicide in the murder analysis files of the Chicago Police Department for the years 1965-1995. For the victim-level file, Part 1, data are provided on the relationship of victim to offender, whether the victim or offender had previously committed a violent or nonviolent offense, time of occurrence and place of homicide, type of weapon used, cause and motivation for the incident, whether the incident involved drugs, alcohol, gangs, child abuse, or a domestic relationship, if or how the offender was identified, and information on the death of the offender(s). Demographic variables such as the age, sex, and race of each victim and offender are also provided. The victim-level file contains one record for each victim. Information for up to five offenders is included on each victim record. The same offender information is duplicated depending on the number of victims. For example, if a sole offender is responsible for five victims, the file contains five victim records with the offender's information repeated on each record. Part 2, Offender-Level Data, is provided to allow the creation of offender rates and risk analysis that could not be accurately prepared using the victim-level file due to the repeating of the offender information on each victim record. Offender variables were reorganized during the creation of the offender file so that each known offender is associated with a single record. A majority of the variables in the offender-level file are replicas of variables in the victim-level file. The offender records contain demographic information about the offender, demographic and relationship information about the offender's first victim (or sole victim if there was only one), and information about the homicide incident. Information pertaining to the homicide incident such as location, weapon, or drug use are the same as in the victim-level file. In cases where the offender data were completely missing in the victim-level data, no offender records were generated in the offender-level file. The offender-level data do not contain information about the victims in these cases. Geographic variables in both files include the census tract, community area, police district, and police area.

Innovative Methodologies for Assessing Radicalization Risk: Risk Terrain Modeling and Conjunctive Analysis, United States, 2001-2019 (ICPSR 38226)
Released/updated on: 2023-04-27
Geographic coverage: United States
Time period: 2001-09-11--2019-12-31
This study examined the geospatial contexts of where terrorism incidents occur, where terrorists plan and prepare for their crimes, and where terrorists reside in the United States. The researchers examined data linked to terrorism-related incidents in the United States from the time of the 9/11 terror attacks in 2001 through 2019. Using these data, the researchers applied innovative analytical methodologies of Risk Terrain Modeling (RTM) and Conjunctive Analysis of Case Configurations (CACC) to evaluate their utility in assessing risk of terrorism.
Risk terrain modeling is a method for identifying situational, place-based risk factors most associated with locations where terrorist incidents are likely to be planned or occur. This method looks at specific aspects of the physical landscape, such as locations of buildings or parking lots. The place-based analysis approach to terrorism investigation represents a shift from the conventional research emphasis on targeting suspicious persons by their demographic or other traits. This approach investigates the importance of location in explanations of crime and terrorism.
According to the American Terrorism Study, during this time between 2001 (after 9/11 and 2019) there were 296 terrorism incidents and 617 pre-incident activities occurred where the state was known. In addition, there were 420 known residences tied to terrorism-related incidents in particular states.

Los Angeles Homicides, 1830-2003 (ICPSR 3680)
Released/updated on: 2012-08-22
Geographic coverage: United States, Los Angeles, California
Time period: 1830-01-01--2003-01-01
There has been little research on United States homicide rates from a long-term perspective, primarily because there has been no consistent data series on a particular place preceding the Uniform Crime Reports (UCR), which began its first full year in 1931. To fill this research gap, this project created a data series that spans two centuries on homicides per capita for the city of Los Angeles. The goal was to create a site-specific, individual-based data series that could be used to examine major social shifts related to homicide, such as mass immigration, urban growth, war, demographic changes, and changes in laws. The basic approach to the data collection was to obtain the best possible estimate of annual counts and the most complete information on individual homicides. Data were derived from multiple sources, including Los Angeles court records, as well as annual reports of the coroner and daily newspapers. Part 1 (Annual Homicides and Related Data) variables include Los Angeles County annual counts of homicides, counts of female victims, method of killing such as drowning, suffocating, or strangling, and the homicide rate. Part 2 (Individual Homicide Data) variables include the date and place of the murder, the age, sex, race, and place of birth of the offender and victim, type of weapon used, and source of data.

National Survey of Weapon-Related Experiences, Behaviors, and Concerns of High School Youth in the United States, 1996 (ICPSR 2580)
Released/updated on: 2005-11-04
Geographic coverage: United States
This national-level survey of youth was undertaken to gather detailed behavioral and attitudinal data concerning weapons and violence. The research project sought to obtain information from a broad sample of high-school-aged youth to achieve diversity regarding history, cultural background, population size and density, urban and non-urban mix, economic situation, and class, race, and ethnic distributions. Data for the study were derived from two surveys conducted during the spring of 1996. The first survey was a lengthy questionnaire that focused on exposure to weapons (primarily firearms and knives) and violence, and was completed by 733 10th- and 11th-grade male students. Detail was gathered on all weapon-related incidents up to 12 months prior to the survey. The second survey, consisting of a questionnaire completed by 48 administrators of the 53 schools that the students attended, provided information regarding school characteristics, levels of weapon-related activity in the schools, and anti-violence strategies employed by the schools. The student survey covered demographic characteristics of the respondent, family living situations, educational situations and aspirations, drug, criminal, and gang activities, crime- and violence-related characteristics of family and friends, respondent's social and recreational activities, exposure to violence generally, personal victimization history, and possession of and activities relating to firearms and knives. Administrators were asked to provide basic demographic data about their schools and to rate the seriousness of violence, drugs, guns, and other weapons in their institutions. They were asked to provide weapon-related information about the average male junior in their schools as well as to estimate the number of incidents involving types of weapons on school grounds during the past three years. The administrators were also asked to identify, from an extensive list of violence reduction measures, those that were practiced at their schools. Variables are also provided about the type of school, grades taught, enrollment, and size of the community. In addition to the data collected directly from students and school administrators, Census information concerning the cities and towns in which the sampled schools were located was also obtained. Census data include size of the city or town, racial and ethnic population distributions, age, gender, and educational attainment distributions, median household and per capita income distributions, poverty rates, labor force and unemployment rates, and violent and property crime rates.

Time period: 1976-01-01--1980-01-01
This evaluation was developed and implemented by the Los Angeles District Attorney's Office to examine the effectiveness of specialized prosecutorial activities in dealing with the local problem of rising gang violence, in particular the special gang prosecution unit Operation Hardcore. One part of the evaluation was a system performance analysis. The purposes of this system performance analysis were (1) to describe the problems of gang violence in Los Angeles and the ways that incidents of gang violence were handled by the Los Angeles criminal justice system, and (2) to document the activities of Operation Hardcore and its effect on the criminal justice system's handling of the cases prosecuted by that unit. Computer-generated listings from the Los Angeles District Attorney's Office of all individuals referred for prosecution by local police agencies were used to identify those individuals who were subsequently prosecuted by the District Attorney. Data from working files on all cases prosecuted, including copies of police, court, and criminal history records as well as information on case prosecution, were used to describe criminal justice handling. Information from several supplementary sources was also included, such as the automated Prosecutors Management Information System (PROMIS) maintained by the District Attorney's Office, and court records from the Superior Court of California in Los Angeles County, the local felony court.

Outcome Evaluation of the Teens, Crime, and the Community/Community Works (TCC/CW) Training Program in Nine Cities Across Four States, 2004-2005 (ICPSR 25865)
Released/updated on: 2011-03-30
Geographic coverage: United States, New Mexico, Massachusetts, Arizona, South Carolina
In 1985, the Teens, Crime, and the Community and Community Works (TCC/CW) program, a collaborative effort by the National Crime Prevention Council (NCPC) and Street Law, Inc., was developed in an effort to reduce adolescent victimization. The purpose of the study was to assess whether the TCC/CW program was successfully implemented and whether it achieved its desired outcome, namely to reduce adolescent victimization. Following an extensive effort to identify potential sites for inclusion in the TCC/CW program outcome evaluation, a quasi-experimental five-wave panel study of public school students was initiated in the fall of 2004. Classrooms in the sample were matched by teacher or subject and one-half of the classrooms received the TCC/CW curriculum while the other half (the control group) was not exposed to the curriculum. A total of 1,686 students representing 98 classrooms in 15 middle schools located in 9 cities in 4 different states were surveyed 3 times: pre-tests in Fall 2004 (Part 1), post-tests in Spring 2005 (Part 2), and through a one-year follow-up survey in Fall 2005 (Part 3). A total of 227 variables are included in Part 1, 297 in Part 2, and 290 in Part 3. Most of these variables are the same across waves, including demographic variables, variables measuring whether the students are involved in extracurricular and other school related activities, community service, religious activities, family activities, employment, or illegal activities and crime, variables measuring the students' views regarding bullying, schoolwork, school and neighborhood violence, property crimes, drug use, alcohol use, gun violence, vandalism, skipping school, inter-racial tensions, neighborhood poverty, and law-enforcement officers, variables measuring how students react to anger, risk, conflict with fellow students, and how they handle long-term versus short-term decision-making, variables measuring group dynamics, variables measuring students' self-esteem, and variables measuring students' awareness of resources in their respective school and neighborhood to address problems and provide support.

Reducing Violent Crime and Firearms Violence in Indianapolis, Indiana, 2003-2005 (ICPSR 20357)
Released/updated on: 2009-01-30
Geographic coverage: Indiana, United States, Indianapolis
Time period: 2003-06-01--2005-03-01
The lever-pulling model was first developed as part of a broad-based, problem-solving effort implemented in Boston in the mid-1990s. The lever-pulling strategy was a foundational element of many collaborative partnerships across the country and it was a central element of the strategic plans of many Project Safe Neighborhoods (PSN) jurisdictions. This effort attempted to deter the future violent behavior of chronic offenders by first communicating directly to them about the impact that violence had on the community and the implementation of new efforts to respond to it, and then giving credibility to this communication effort by using all available legal sanctions (i.e., levers) against these offenders when violence occurred. The purpose of the study was to perform an experimental evaluation of a lever-pulling strategy implemented in Indianapolis, Indiana. Probationers were randomly assigned to the law enforcement focused lever-pulling group, the community leader lever-pulling group, or a regular probation control group during six months between June 2003 and March 2004. There were a total of 540 probationers in the study--180 probationers in each group. Probationers in the law enforcement focused lever-pulling group had face-to-face meetings with federal and local law enforcement officials and primarily received a deterrence-based message, but community officials also discussed various types of job and treatment opportunities. In contrast, probationers in the community leader lever-pulling group attended meetings with community leaders and service providers who exclusively focused on the impact of violence on the community and available services. Three types of data were collected to assess perceptions about the meeting: offending behavior, program participation behavior, and the levers pulled. First, data were collected using a self-report survey instrument (Part 1). Second, the complete criminal history for probationers (Part 2) was collected one-year after their meeting date. Third, all available probation data (Part 3) were collected 365 days after the meeting date. Part 1, Self-Report Survey Data, includes a total of 316 variables related to the following three types of data: Section I: meeting evaluation and perception of risk, Section II: Self-reported offense and gun use behavior, and Section III: Demographics. Part 2, Criminal History Data, includes a total of 94 variables collected about the probationer's complete offending history as well as their criminal activities after the treatment for one year. Part 3, Probation Data, includes a total of 249 variables related to probation history and other outcome data.

This study identified the temporal dimensions of terrorists' precursor conduct to determine if these behaviors occurred in a logically sequenced pattern, with a particular focus on the identification of sequenced patterns that varied by group type, group size, and incident type. The study specifically focused on how these pre-incident activities were associated with the successful completion or prevention of terrorist incidents and how they differed between categories of terrorism. Data utilized for this study came from the American Terrorism Study (ATS), a database that includes "officially designated" federal terrorism cases from 1980-October 1, 2016, collected for the National Institute of Justice.
The project focused on three major issues related to terrorists' precursor behaviors:
- A subgroup analysis of temporal, crime-specific patterns by group type,
- The nature of the planning process, and
- Factors associated with the outcomes of terrorist incidents (success or failure).

Survey of Prison Inmates, United States, 2016 (ICPSR 37692)
Released/updated on: 2024-03-28
Geographic coverage: United States
To fulfill part of its mission, the Bureau of Justice Statistics (BJS) conducted the Survey of Prison Inmates (SPI), a national, wide-ranging survey of prisoners age 18 or older who were incarcerated in state or federal correctional facilities within the United States. SPI provides national statistics on prisoner characteristics across a variety of domains, such as current offense and sentence, incident characteristics, firearm possession and sources, criminal history, demographic and socioeconomic characteristics, family background, drug and alcohol use and treatment, mental and physical health and treatment, and facility programs and rules violations. SPI can also be used to track changes in these characteristics over time, describe special populations of prisoners, and identify policy-relevant changes in the state and federal prison populations. Formerly the Survey of Inmates in State and Federal Correctional Facilities (SISFCF), this survey was renamed SPI with the 2016 iteration.

Testing the Efficacy of the SANE-SART Programs in Kansas, Massachusetts, and New Jersey, 1997-2001 (ICPSR 20341)
Released/updated on: 2008-10-01
Geographic coverage: United States, Massachusetts, Kansas, New Jersey
Time period: 1997-01-01--2001-01-01
The purpose of the study was to explore the impact of interventions by Sexual Assault Nurse Examiners/Sexual Assault Response Teams (SANE/SART) on the judicial process. The goal was to test the efficacy of SANE/SART programs as a tool in the criminal justice system. The American Prosecutors Research Institute and Boston College tested the hypotheses that SANE/SART exams increase arrest and prosecution rates. The researchers collected case information from SANE/SART, police, and prosecution files in three jurisdictions: Monmouth County (Freehold), New Jersey, Sedgwick County (Wichita), Kansas, and Suffolk County (Boston), Massachusetts. At each study site, the project team randomly selected up to 125 sexual assault cases in which there was a SANE or SART intervention and 125 cases in which there was no SANE/SART intervention from cases that were opened and closed between 1997 and 2001. Comparisons were sought between SANE/SART cases (both SANE only and SANE/SART combined) and non-SANE/SART cases to determine if the intervention predicted the likelihood of certain criminal justice system outcomes. These outcomes included identification/arrest of a suspect, the filing of charges, case disposition, type of penalty, and length of sentence. In addition, researchers collected information on a number of other variables that could impact or mitigate the effect of SANE/SART interventions and case outcomes. The researchers abstracted information from case files maintained by SANE programs, police incident/arrest reports, and prosecution files during intensive five-day site visits. Three standardized records abstraction forms were developed to collect data: (1) the incident form was designed to collect data from police reports and the prosecution files about the actual sexual assault, (2) the case abstraction form was designed to collect prosecution data and case outcome data from the prosecutors' case files, and (3) the SANE/SART data collection form collected information from the SANE/SART files about the SANE/SART intervention. Specific information regarding the evidence collected during the victim's exam, nature of the assault, evidence/forensic kits collected, victim's demeanor, weapon(s) used, number of assailants, and the victim/offender relationship were collected.
