Arson Measurement, Analysis, and Prevention in Massachusetts, 1983-1985 (ICPSR 9972)
Released/updated on: 2006-03-30
Geographic coverage: United States, Massachusetts
Time period: 1983-01-01--1985-01-01
These data were gathered to test a model of the socioeconomic and demographic determinants of the crime of arson. Datasets for this analysis were developed by the principal investigator from records of the Massachusetts Fire Incident Reporting System and from population and housing data from the 1980 Census of Massachusetts. The three identically-structured data files include variables such as population size, fire incident reports, employment, income, family structure, housing type, housing quality, housing occupancy, housing availability, race, and age.

Exploratory Spatial Data Approach to Identify the Context of Unemployment-Crime Linkages in Virginia, 1995-2000 (ICPSR 4546)
Released/updated on: 2006-08-31
Geographic coverage: United States, Virginia
Time period: 1995-01-01--2000-01-01
This research is an exploration of a spatial approach to identify the contexts of unemployment-crime relationships at the county level. Using Exploratory Spatial Data Analysis (ESDA) techniques, the study explored the relationship between unemployment and property crimes (burglary, larceny, motor vehicle theft, and robbery) in Virginia from 1995 to 2000. Unemployment rates were obtained from the Department of Labor, while crime rates were obtained from the Federal Bureau of Investigation's Uniform Crime Reports. Demographic variables are included, and a resource deprivation scale was created by combining measures of logged median family income, percentage of families living below the poverty line, and percentage of African American residents.

Investigating Root Causes of School Violence: A Case-Control Study of School Violence Offenders, Non-School Youth Violence Offenders, and Non-Offending Youths, United States, 1990-2020 (ICPSR 39020)
Released/updated on: 2024-10-30
Geographic coverage: United States
Time period: 1990-01-01--2020-01-01
This study investigated root causes of school shootings by using a case-control methodology to compare 157 adolescent school shooters (cases) to samples of two key comparison groups: 157 non-school adolescent shooting offenders and 157 non-offending youths who attended the same school as the school shooter (controls) in the United States between 1990 and 2020 (overall n=471). Specifically, the researchers compared:
- Adolescent school shooters who committed shootings both fatal and non-fatal to adolescents who committed shootings both fatal and non-fatal outside school grounds in the community.
- Adolescent school shooters who committed homicide to adolescents who committed shooting homicides outside school grounds in the community.
- Adolescent school shooters who caused non-fatal injuries to adolescents who committed non-fatal shootings with injuries outside school grounds in the community.
- Adolescent school shooters to non-offending students from the same school.
All groups were compared on items theorized to be risk and protective factors to crime based on major criminology theories, such as social learning, general strain, social control, bio-social, life course, and psychology. Building upon the methodology used in The American School Shooting Study (TASSS), this study relied on open-source, content analysis research methods to obtain all publicly available information on the sampled individuals. Files were collected from over 60 databases, major search engines, and archival resources, which were then reviewed and coded by the research team for evidence of risk and protective factors.

Outcome Evaluation of the Comprehensive Indian Resources for Community and Law Enforcement (CIRCLE) Project With Data From Nine Tribes in the United States, 1995-2004 (ICPSR 20402)
Released/updated on: 2015-01-20
Geographic coverage: United States
Time period: 1995-01-01--2004-01-01
The data for this study were collected in Phase 2, the outcome evaluation, of the Comprehensive Indian Resources for Community and Law Enforcement (CIRCLE) Project. The CIRCLE Project was launched in the late 1990s to strengthen tribal justice systems and, through effective tribal-level planning and strategic comprehensive approaches, to better equip Native American nations to combat the interlinked community problems of crime, violence, substance abuse, and juvenile delinquency. The Native American nations invited to participate in the CIRCLE Project were the Northern Cheyenne, the Ogling Sioux, and the Zuni. Part 1, Participant Data, contains data on each of the Native American nations. The Northern Cheyenne data include variables on juvenile arrests between 1995 and 2003 for intoxication, curfew violations, disorderly conduct, and total arrests. The Oglala Sioux data include variables on police force stability and court pleadings. The Zuni data include variables on arrests for simple assault, public intoxication, driving while intoxicated (DWI), endangerment, domestic violence, and total arrests between 2001 and 2004. Part 2, United States Department of Justice Funding Data, contains data on funding given to the Northern Cheyenne, the Oglala Sioux, the Zuni, and six comparison Native American nations for fiscal years 1998 to 2003.

Repeat Complaint Address Policing: Two Field Experiments in Minneapolis, 1985-1987 (ICPSR 9788)
Released/updated on: 2006-01-18
Geographic coverage: Minneapolis, United States, Minnesota
Time period: 1985-01-01--1987-01-01
A leading sociological theory of crime is the "routine activities" approach (Cohen and Felson, 1979). The premise of this theory is that the rate of occurrence of crime is affected by the convergence in time and space of three elements: motivated offenders, suitable targets, and the absence of guardianship against crime. The purpose of this study was to provide empirical evidence for the routine activities theory by investigating criminal data on places. This study deviates from traditional criminology research by analyzing places instead of collectivities as units of spatial analysis. There are two phases to this study. The purpose of the first phase was to test whether crime occurs randomly in space or is concentrated in "hot spots". Telephone calls for police service made in 1985 and 1986 to the Minneapolis Police Department were analyzed for patterns and concentration of repeat calls and were statistically tested for randomness. For the second phase of the study, two field experiments were designed to test the effectiveness of a proactive police strategy called Repeat Complaint Address Policing (RECAP). Samples of residential and commercial addresses that generated the most concentrated and most frequent repeat calls were divided into groups of experimental and control addresses, resulting in matched pairs. The experimental addresses were then subjected to a more focused proactive policing. The purposes of the RECAP experimentation were to test the effectiveness of proactive police strategy, as measured through the reduction in the incidence of calls to the police and, in so doing, to provide empirical evidence on the routine activities theory. Variables in this collection include the number of calls for police service in both 1986 and 1987 to the control addresses for each experimental pair, the number of calls for police service in both 1986 and 1987 to the experimental addresses for each experimental pair, numerical differences between calls in 1987 and 1986 for both the control addresses and experimental addresses in each experimental pair, percentage difference between calls in 1987 and 1986 for both the control addresses and the experimental addresses in each experimental pair, and a variable that indicates whether the experimental pair was used in the experimental analysis. The unit of observation for the first phase of the study is the recorded telephone call to the Minneapolis Police Department for police service and assistance. The unit of analysis for the second phase is the matched pair of control and experimental addresses for both the residential and commercial address samples of the RECAP experiments.

Trends in Substance Abuse and Treatment Needs Among Inmates in the United States, 1996-1997 (ICPSR 3714)
Released/updated on: 2006-01-18
Geographic coverage: United States
Time period: 1996-01-01--1997-01-01
This data collection consists of the SPSS syntax used to recode existing variables and create new variables from the SURVEY OF INMATES OF LOCAL JAILS, 1996 [ICPSR 6858] and the SURVEY OF INMATES IN STATE AND FEDERAL CORRECTIONAL FACILITIES, 1997 [ICPSR 2598]. Using the data from these two national surveys on jail and prison inmates, this study sought to expand the analyses of these data in order to fully explore the relationship between type and intensity of substance abuse and other health and social problems, analyze access to treatment and services, and make estimates of the need for different types of treatment services in correctional systems.
