Adjusting the National Crime Victimization Survey's Estimates of Rape and Domestic Violence for Gag Factors, 1986-1990 (ICPSR 6558)

Released/updated on: 1996-10-01

Geographic coverage: United States

Time period: 1986-01-01--1990-01-01

The purpose of this project was to use statistical modeling techniques to estimate rape and domestic assault rates, adjusting for interviewing conditions under which the National Crime Victimization Survey (NCVS) was administered. Data for women 16 years of age and older interviewed in the NCVS (see NATIONAL CRIME SURVEYS: NATIONAL SAMPLE, 1986-1990 [NEAR-TERM DATA] [ICPSR 8864]) were analyzed. The researchers considered whether the type of interview (personal or telephone) and the presence of another person (particularly a spouse) influenced or "gagged" the reporting of rape and domestic violence in the NCVS. The researchers also investigated correlates, primarily demographic in nature, of reporting rape, domestic violence, other assaults, and breaking and entry. In total, the data file contains reports of 434 rapes, 1,973 incidents of domestic violence, 13,459 other assaults, and 88,950 incidents of breaking and entry. The binary-coded variables provide information on whether the respondent was alone during the interview, others who were present, whether the interview was by telephone, whether the respondent refused a telephone interview, the number of persons who lived in the household, whether the respondent owned her home, whether the land use was urban, whether the household the respondent was living in was the same household from the last interview, whether the respondent had moved more than three times in the last five years, and whether an assault, domestic violence incident, rape, breaking and entry, or no crime was reported. Demographic information includes the respondent's education, income, employment during the last six months, marital status at the time of the interview, and whether the respondent was white (or non-white) or Hispanic (or non-Hispanic). Variables coded the same as the NCVS variables include age, respondent's relationship to the offender, type of crime, year and quarter of interview, NCVS control number, and person weight.

Adult Criminal Careers, Michigan: 1974-1977 (ICPSR 8279)

Released/updated on: 1995-03-31

Geographic coverage: United States, Michigan

Time period: 1974-01-01--1977-01-01

These data, taken from the computerized criminal history files of the Federal Bureau of Investigation, were collected to develop estimates of the extent and variation of individual offending. Included are the adult criminal records of individuals 17 years of age and older arrested in Michigan from 1974 to 1977. The primary criterion for inclusion in the sample was at least one arrest in Michigan for murder, rape, robbery, aggravated assault, burglary, or auto theft. Once sampled, the arrest history includes data on all recorded arrests through 1977, regardless of offense type. The full dataset includes records for 41,191 individuals for a total of 200,007 arrests. The dataset is organized by individual and includes demographic characteristics of the individual (birth date, state of birth, sex, and race) followed by information from the individual's arrest record in chronological order. The arrest records include the date of arrest, the offenses charged, the disposition (convicted, dismissed, or acquitted), and the sentence. Because the data are organized by individual, they are suitable for longitudinal analyses of individual offending patterns over time.

Bethlehem [Pennsylvania] Police Family Group Conferencing Project, 1993-1997 (ICPSR 2679)

Released/updated on: 2006-03-30

Geographic coverage: United States, Bethlehem, Pennsylvania

Time period: 1993-01-01--1997-01-01

The purpose of this study was to evaluate the implementation of conferencing as a restorative policing practice. Family group conferencing is considered an important new development in restorative justice practice as a means of dealing more effectively with young first-time offenders by diverting them from court and involving their extended families and victims in conferences to address their wrongdoing. Cases deemed eligible for the study were property crimes including retail and other thefts, criminal mischief and trespass, and violent crimes including threats, harassment, disorderly conduct, and simple assaults. A total of 140 property crime cases and 75 violent crime cases were selected for the experiment, with two-thirds of each type randomly assigned to a diversionary conference (treatment group) and one-third of each type assigned to formal adjudication (control group). Participation in the conference was voluntary. If either party declined or if the offender did not admit responsibility for the offense, the case was processed through normal criminal justice channels. Those cases constituted a second treatment group (decline group). The Bethlehem, Pennsylvania, Police Department and the Community Service Foundation conducted a two-year study on the effectiveness of police-based family group conferencing. Beginning on November 1, 1995, 64 conferences were conducted for the study. Approximately two weeks after their cases were disposed, victims, offenders, and offenders' parents in the three experimental groups (control, conference, decline) were surveyed by mail, in-person interviews, or telephone interviews. Those who participated in conferences (Parts 4, 6, and 8) received a different questionnaire than those whose cases went through formal adjudication (Parts 5, 7, and 9), with similar questions to allow for comparison and some questions particular to the type of processing used on their case. Disposition data on cases were collected from five district magistrates in Bethlehem from January 1, 1993, to September 12, 1997. Data on recidivism and outcomes of the control and decline group cases were obtained from (1) the Bethlehem Police Department arrest database (Part 1) and (2) a database of records from the five district magistrates serving Bethlehem, drawn from a statewide magistrate court database compiled by the Administrative Office of Pennsylvania Courts (Part 2). An attitudinal and work environment survey was administered to the Bethlehem Police Department on two occasions, just before the conferencing program commenced (pre-test) and eighteen months later (post-test) (Part 3). Part 1 variables include offender age, year of offense, charge code, amounts of fine and payments, crime type, offender crime category, and disposition. Part 2 collected disposition data on cases in the study and officers' observations on the conferences. Demographic variables include offender's age at current arrest, ethnicity, and gender. Other variables include type of charge, arrest, disposition, sentence, and recidivism, reason not conferenced, current recorded charge class, amounts of total fines, hours of community service, and conditions of sentence. Part 3 collected information on police attitudes and work environment before and after the conferencing program. Variables on organizational issues include ratings on communication, morale, co-workers, supervision, administration, amenities, equipment, and promotions. Variables on operational issues include ratings on danger, victims, frustration, external activities, complaints, workload, and driving. In Parts 4 to 9, researchers asked offenders, parents of offenders, and victims about their perceptions of how their cases were handled by the justice system and the fairness of the process, their attitudes and beliefs about the justice system, and their attitudes toward the victim and offender. Variables include whether the respondent was satisfied with the way the justice system handled the case, if the offender was held accountable for the offense, if meeting with the victim was helpful, if the respondent was surprised by anything in the conference, if the respondent told the victim/offender how he/she felt, if there was an opportunity to reach an agreement acceptable to all, if the offender/parents apologized, if the victim/parents had a better opinion of the offender after the conference, what the respondent's attitude toward the conference was, if the respondent would recommend a conference to others, if the offender was pressured to do all the talking, if the offender was treated with respect, if victim participation was insincere, if the respondent had a better understanding of how the victim was affected, if the victim only wanted to be paid back, and if conferences were responsive to needs.

Calls for Service to Police as a Means of Evaluating Crime Trends in Oklahoma City, 1986-1988 (ICPSR 9669)

Released/updated on: 2006-01-12

Geographic coverage: Oklahoma City, United States, Oklahoma

Time period: 1986-06-01--1988-06-01

In an effort to measure the effectiveness of crime deterrents and to estimate crime rates, calls for assistance placed to police in Oklahoma City over a two-year period were enumerated. This type of call was studied in order to circumvent problems such as "interviewer's effect" and sampling errors that occur with other methods. The telephone calls were stratified by police district, allowing for analysis on the neighborhood level to determine whether deterrence operates ecologically--that is, by neighbors informing one another about arrests which took place as a result of their calls to the police. In measuring deterrence, only the calls that concerned robbery were used. To estimate crime rates, calls were tallied on a monthly basis for 18 types of offenses: aggravated assault, robbery, rape, burglary, grand larceny, motor vehicle theft, simple assault, fraud, child molestation, other sex offenses, domestic disturbance, disorderly conduct, public drunkenness, vice and drugs, petty larceny, shoplifting, kidnapping/hostage taking, and suspicious activity.

Criminal Victimization Among Women in Cleveland, Ohio: Impact on Health Status and Medical Service Usage, 1986 (ICPSR 9920)

Released/updated on: 2006-01-12

Geographic coverage: United States, Ohio, Cleveland

The impact of criminal victimization on the health status of women is the focus of this data collection. The researchers examined the extent to which victimized women differed from nonvictimized women in terms of their physical and psychological well-being and differences in their use of medical services. The sample was drawn from female members of a health maintenance plan at a worksite in Cleveland, Ohio. Questions used to measure criminal victimization were taken from the National Crime Survey and focused on purse snatching, home burglary, attempted robbery, robbery with force, threatened assault, and assault. In addition, specific questions concerning rape and attempted rape were developed for the study. Health status was assessed by using a number of instruments, including the Cornell Medical Index, the Mental Health Index, and the RAND Corporation test battery for their Health Insurance Experiment. Medical service usage was assessed by reference to medical records. Demographic information includes age, race, income, and education.

Detection of Crime, Resource Deployment, and Predictors of Success: A Multi-Level Analysis of CCTV in Newark, New Jersey, 2007-2011 (ICPSR 34619)

Released/updated on: 2019-09-24

Geographic coverage: United States, Newark, New Jersey

Time period: 2007-11-01--2011-04-01

The Detection of Crime, Resource Deployment, and Predictors of Success: A Multi-Level Analysis of Closed-Circuit Television (CCTV) in Newark, NJ collection represents the findings of a multi-level analysis of the Newark, New Jersey Police Department's video surveillance system. This collection contains multiple quantitative data files (Datasets 1-14) as well as spatial data files (Dataset 15 and Dataset 16). The overall project was separated into three components:

Component 1 (Dataset 1, Individual CCTV Detections and Calls-For-Service Data and Dataset 2, Weekly CCTV Detections in Newark Data) evaluates CCTV's ability to increase the "certainty of punishment" in target areas;
Component 2 (Dataset 3, Overall Crime Incidents Data; Dataset 4, Auto Theft Incidents Data; Dataset 5, Property Crime Incidents Data; Dataset 6, Robbery Incidents Data; Dataset 7, Theft From Auto Incidents Data; Dataset 8, Violent Crime Incidents Data; Dataset 9, Attributes of CCTV Catchment Zones Data; Dataset 10, Attributes of CCTV Camera Viewsheds Data; and Dataset 15, Impact of Micro-Level Features Spatial Data) analyzes the context under which CCTV cameras best deter crime. Micro-level factors were grouped into five categories: environmental features, line-of-sight, camera design and enforcement activity (including both crime and arrests); and
Component 3 (Dataset 11, Calls-for-service Occurring Within CCTV Scheme Catchment Zones During the Experimental Period Data; Dataset 12, Calls-for-service Occurring Within CCTV Schemes During the Experimental Period Data; Dataset 13, Targeted Surveillances Conducted by the Experimental Operators Data; Dataset 14, Weekly Surveillance Activity Data; and Dataset 16, Randomized Controlled Trial Spatial Data) was a randomized, controlled trial measuring the effects of coupling proactive CCTV monitoring with directed patrol units.

Over 40 separate four-hour tours of duty, an additional camera operator was funded to monitor specific CCTV cameras in Newark. Two patrol units were dedicated solely to the operators and were tasked with exclusively responding to incidents of concern detected on the experimental cameras. Variables included throughout the datasets include police report and incident dates, crime type, disposition code, number of each type of incident that occurred in a viewshed precinct, number of CCTV detections that resulted in any police enforcement, and number of schools, retail stores, bars and public transit within the catchment zone.

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 purpose of this study was to investigate violence and aggression committed by nursing home residents that is directed toward other residents, referred to here as resident-to-resident elder mistreatment (R-REM). Resident-to-resident mistreatment (R-REM) was defined as: negative and aggressive physical, sexual, or verbal interactions between long term care residents, that in a community setting would likely be construed as unwelcome and have high potential to cause physical or psychological distress in the recipient.

The goals of this project were to: enhance institutional recognition of R-REM; examine the convergence of R-REM reports across different methodologies; identify the most accurate mechanism for detecting and reporting R-REM; develop profiles of persons involved with R-REM by reporting source; investigate existing R-REM policies, and; develop institutional guidelines for reporting R-REM episodes. Also, the project team sought to answer the following research questions: (1) Will the reporting of R-REM differ by source? (2) Which reporting methods will show the highest level of convergence and accuracy in reporting? (3) What resident characteristics or profiles will predict R-REM across the differing reporting sources? (4) What are the existing guidelines and/or institutional policies for reporting R-REM? To achieve these goals, the researcher conducted this study over a two week period in five urban and five suburban New York City facilities. Resident-to-resident abuse information was derived from five sources: (1) resident interviews (2) staff informants (3) observational data (behavior sheets) (4) resident chart reviews (5) incident and accident reports.

This study presents a research-informed approach to identify the most efficient practices for addressing un-submitted sexual assault kits (SAKs) that accrue in U.S. law enforcement agencies (LEAs) as well as untested SAKs pending analysis in crime laboratories. The study examined intra- and interagency dynamics associated with SAK processing efficiency in a linked sample of crime laboratories. SAK outputs and inputs were assessed for laboratories that conduct biological forensic analysis and LEAs that submit SAK evidence to these laboratories. Production functions were estimated to examine effects of labor and capital inputs, in addition to policies, management systems, and cross-agency coordination on efficiency. Six jurisdictions were recruited for site visits, and qualitative methods were used to understand how LEAs, laboratories, and prosecutors implement practices that affect efficiency.

Geographic coverage: United States, Michigan

Time period: 2000-01-01--2001-01-01

In the past few years it has become alarmingly clear that women with disabilities are at an extremely high risk for emotional, sexual, and physical assault. The Developmental Disabilities Institute at Wayne State University, in collaboration with the United Cerebral Palsy Association in Michigan, conducted a one-year study to investigate the prevalence and correlates of, and service system capacity related to, domestic abuse among women with physical disabilities in Michigan. The study aimed to address the following research questions: (1) What is the prevalence of domestic violence among a sample of women with physical disabilities? (2) What potential factors for domestic violence exist among women with physical disabilities? and (3) What is the capacity of existing support programs (e.g., safe houses, shelters, and service agencies) to assist women with physical disabilities? The population for this study was women over the age of 18 who had physical disabilities. Consistent with the work of other researchers, physical disabilities in this study were defined as those disabilities that result in functional impairment, such as cerebral palsy, post-polio syndrome, spina bifida, amputation, rheumatic conditions, multiple sclerosis, spinal cord injury, traumatic brain injury, visual impairment, hearing impairment, and stroke. A sample of 177 women was recruited through several mechanisms. To address the question of domestic abuse prevalence, the women participating in the study were first asked to complete a brief questionnaire addressing demographic characteristics and their experience with domestic violence (Part 1, Screening Interview Data). Fifty-six percent (100) of the 177 women interviewed indicated a positive history of abuse at their initial screening. In order to address the second research question about the correlates of abuse, this subsample of 100 women was invited and encouraged to participate in the second phase of the research, which involved a more extensive interview (Part 2, Abuse Interview Data). The interview used was based on a protocol developed by Nosek (1995) that addressed demographic characteristics, social networks, and abuse history. Variables in Parts 1 and 2 include type of disability, type of personal assistance needed, and whether the respondent was ever physically, emotionally, or sexually abused. Part 2 also contains variables on sources of monthly income, who perpetrated the abuse, the abuser's gender, how long the victim knew the abuser, whether the victim sought assistance from a domestic violence program or shelter, and a description of the worst incident of physical abuse. Demographic variables in Parts 1 and 2 include ethnicity, age, employment status, and marital status.

Examination of Crime Guns and Homicide in Pittsburgh, Pennsylvania, 1987-1998 (ICPSR 2895)

Released/updated on: 2006-03-30

Geographic coverage: United States, Pennsylvania, Pittsburgh

This study examined spatial and temporal features of crime guns in Pittsburgh, Pennsylvania, in order to ascertain how gun availability affected criminal behavior among youth, whether the effects differed between young adults and juveniles, and whether that relationship changed over time. Rather than investigating the general prevalence of guns, this study focused only on those firearms used in the commission of crimes. Crime guns were defined specifically as those used in murders, assaults, robberies, weapons offenses, and drug offenses. The emphasis of the project was on the attributes of crime guns and those who possess them, the geographic sources of those guns, the distribution of crime guns over neighborhoods in a city, and the relationship between the prevalence of crime guns and the incidence of homicide. Data for Part 1, Traced Guns Data, came from the City of Pittsburgh Bureau of Police. Gun trace data provided a detailed view of crime guns recovered by police during a two-year period, from 1995 to 1997. These data identified the original source of each crime gun (first sale to a non-FFL, i.e., a person not holding a Federal Firearms License) as well as attributes of the gun and the person possessing the gun at the time of the precipitating crime, and the ZIP-code location where the gun was recovered. For Part 2, Crime Laboratory Data, data were gathered from the local county crime laboratory on guns submitted by Pittsburgh police for forensic testing. These data were from 1993 to 1998 and provided a longer time series for examining changes in crime guns over time than the data in Part 1. In Parts 3 and 4, Stolen Guns by ZIP-Code Data and Stolen Guns by Census Tract Data, data on stolen guns came from the local police. These data included the attributes of the guns and residential neighborhoods of owners. Part 3 contains data from 1987 to 1996 organized by ZIP code, whereas Part 4 contains data from 1993 to 1996 organized by census tract. Part 5, Shots Fired Data, contains the final indicator of crime gun prevalence for this study, which was 911 calls of incidents involving shots fired. These data provided vital information on both the geographic location and timing of these incidents. Shots-fired incidents not only captured varying levels of access to crime guns, but also variations in the willingness to actually use crime guns in a criminal manner. Part 6, Homicide Data, contains homicide data for the city of Pittsburgh from 1990 to 1995. These data were used to examine the relationship between varying levels of crime gun prevalence and levels of homicide, especially youth homicide, in the same city. Part 7, Pilot Mapping Application, is a pilot application illustrating the potential uses of mapping tools in police investigations of crime guns traced back to original point of sale. NTC. It consists of two ArcView 3.1 project files and 90 supporting data and mapping files. Variables in Part 1 include date of manufacture and sale of the crime gun, weapon type, gun model, caliber, firing mechanism, dealer location (ZIP code and state), recovery date and location (ZIP code and state), age and state of residence of purchaser and possessor, and possessor role. Part 2 also contains gun type and model, as well as gun make, precipitating offense, police zone submitting the gun, and year the gun was submitted to the crime lab. Variables in Parts 3 and 4 include month and year the gun was stolen, gun type, make, and caliber, and owner residence. Residence locations are limited to owner ZIP code in Part 3, and 1990 Census tract number and neighborhood name in Part 4. Part 5 contains the date, time, census tract and police zone of 911 calls relating to shots fired. Part 6 contains the date and census tract of the homicide incident, drug involvement, gang involvement, weapon, and victim and offender ages. Data in Part 7 include state, county, and ZIP code of traced guns, population figures, and counts of crime guns recovered at various geographic locations (states, counties, and ZIP codes) where the traced guns first originated in sales by an FFL to a non-FFL individual. Data for individual guns are not provided in Part 7.

Examination of South Carolina's Sex Offender Registration and Notification (SORN) Policy in Reducing Sexual Violence, 1990-2005 (ICPSR 31502)

Released/updated on: 2015-07-30

Geographic coverage: United States, South Carolina

Time period: 1990-01-01--2005-01-01

This study examined the effects of comprehensive registration and community notification policies on rates of sexual violence in South Carolina. Specifically, it proposed to (1) evaluate whether broad sex offender registration and notification policies have reduced recidivism or deterred new sexual offenses, (2) examine whether unintended effects of broad registration and notification policies occurred, and (3) focus on the effects of registration and notification as it pertained to offenses committed by adults. The study examined whether the introduction of sex offender registration and notification laws in South Carolina were associated with reductions in sexual crimes and, if so, whether this reduction could be attributed to an actual reduction in sexual violence and/or recidivism (i.e., an intended effect) or to changes in criminal judicial processing of individuals for registry crimes (i.e., an unintended effect).

Specific study aims included examining whether: (1) South Carolina registration and notification policies had the intended effect of preventing first time sexual offending; (2) South Carolina registration and notification policies had the intended effect of reducing sexual recidivism for known sex offenders; and (3) South Carolina registration and notification policies had the unintended effect of reducing the probability that individuals who committed sexual crimes would be prosecuted or convicted for such crimes. In addition to these primary aims, the researchers also investigated (4) registration violations (e.g., failure to register) were associated with sexual or general recidivism.

Exploring the Drugs-Crime Connection Within the Electronic Dance Music and Hip Hop Nightclub Scenes in Philadelphia, Pennsylvania, 2005-2006 (ICPSR 21187)

Released/updated on: 2013-01-15

Geographic coverage: United States, Philadelphia, Pennsylvania

Time period: 2005-04-01--2006-12-01

To explore the relationship between alcohol, drugs, and crime in the electronic dance music and hip hop nightclub scenes of Philadelphia, Pennsylvania, researchers utilized a multi-faceted ethnographic approach featuring in-depth interviews with 51 respondents (Dataset 1, Initial Interview Qualitative Data) and two Web-based follow-up surveys with respondents (Dataset 2, Follow-Up Surveys Quantitative Data). Recruitment of respondents began in April of 2005 and was conducted in two ways. Slightly more than half of the respondents (n = 30) were recruited with the help of staff from two small, independent record stores. The remaining 21 respondents were recruited at electronic dance music or hip hop nightclub events. Dataset 1 includes structured and open-ended questions about the respondent's background, living situation and lifestyle, involvement and commitment to the electronic dance music and hip hop scenes, nightclub culture and interaction therein, and experiences with drugs, criminal activity, and victimization. Dataset 2 includes descriptive information on how many club events were attended, which ones, and the activities (including drug use and crime/victimization experiences) taking place therein. Dataset 3 (Demographic Quantitative Data) includes coded demographic information from the Dataset 1 interviews.

Firearm Legislation and Firearm Violence Across Space and Time, United States, 1970-2012 (ICPSR 36688)

Released/updated on: 2018-05-15

Geographic coverage: United States

Time period: 1970-01-01--2012-01-01

The study constructed a comprehensive, longitudinal dataset of all counties nested within U.S. States from 1970 to 2012. The study's main purpose was to facilitate research that would further understanding on firearm legislation and its impacts on violence. This comprehensive data collection effort included information on firearm legislation implemented across U.S. States over time in combination with multiple measures of firearm-related violence and injury. Moreover, to better understand the conditions under which firearm legislation is more or less effective, incorporation of county characteristics allowed for examination of whether the effectiveness of state-level firearm legislation depends upon particular characteristics of counties. The researchers conducted a secondary analysis utilizing a variety of archived external government and census sources.

The Study's Dataset Include two Stata Files:

Governmental Responses to Crime in the United States, 1948-1978 (ICPSR 8076)

Released/updated on: 1992-02-16

Geographic coverage: United States

Time period: 1948-01-01--1978-01-01

The Governmental Responses to Crime Project was initiated in October 1978 as a result of the rising crime rate in urban areas of the United States and the wide variety of programs seeking to contain it. The project investigated the way in which urban governments, citizens, newspapers and state governments responded to the growth and increasing complexity of crime during the period from 1948 to 1978. Pertinent variables in this data collection include the number of police officers in cities and police expenditures, changes in laws as crime changes, populations, employment rates, family incomes, percent of non-white population, media tracking of crime, city land area, kinds of crimes, crime rates, actual numbers of offenses, penalties given out for crimes committed (time in jail or prison and fines), focus on crimes within certain geographical areas (from within cities or outside the United States), editorial page content, level of prominence of newspaper articles on individual crimes, and the number of editorials relating to specific crimes.

Impact of Forensic Evidence on Arrest and Prosecution (IFEAP) in Connecticut, United States, 2006-2009 (ICPSR 36695)

Released/updated on: 2018-04-09

Geographic coverage: Connecticut

Time period: 2006-01-01--2009-01-01

This research was conducted in two phases. Phase one analyzed a random sample of approximately 2,000 case files from 2006 through 2009 that contain forensic analyses from the Connecticut State Forensic Science Laboratory, along with corresponding police and court case file data. As with Peterson, et al. (2010), this research had four objectives: 1) estimate the percentage of cases in which crime scene evidence is collected; 2) discover what kinds of forensic are being collected; 3)track such evidence through the criminal justice system; and 4)identify which forms of forensic evidence are most efficacious given the crime investigated.

Phase two consisted of a survey administered to detectives within the State of Connecticut regarding their comparative assessments of the utility of forensic evidence. These surveys further advance our understanding of how the success of forensic evidence in achieving arrests and convictions matches with detective opinion.

Impact of Violent Victimization on Physical and Mental Health Among Women in the United States, 1994-1996 (ICPSR 21020)

Released/updated on: 2007-10-26

Geographic coverage: United States

Time period: 1994-11-01--1996-05-01

The major goals of the project were to use survey data about victimization experiences among American women to examine: (a) the consequences of victimization for women's physical and mental health, (b) how the impact of victimization on women's health sequelae is conditioned by the victim's invoking of family and community support, and (c) how among victims of intimate partner violence, such factors as the relationship between the victim and offender, the offender's characteristics, and police involvement condition the impact of victimization on the victim's subsequent physical and mental health. This data collection consists of the SPSS syntax used to recode existing variables and create new variables from the study, VIOLENCE AND THREATS OF VIOLENCE AGAINST WOMEN AND MEN IN THE UNITED STATES, 1994-1996 (ICPSR 2566). The study, also known as the National Violence against Women Survey (NVAWS), surveyed 8,000 women 18 years of age or older residing in households throughout the United States in 1995 and 1996. The data for the NVAWS were gathered via a national, random-digit dialing sample of telephone households in the United States, stratified by United States Census region. The NVAWS respondents were asked about their lifetime experiences with four different kinds of violent victimization: sexual abuse, physical abuse, stalking, and intimidation. Using the data from the NVAWS, the researchers in this study performed three separate analyses. The study included outcome variables, focal variables, moderator variables, and control variables.

Geographic coverage: Milwaukee, United States, Wisconsin

Time period: 2015-01-01--2016-07-01

The study investigated the feasibility of implementing the Cardiff Model. The Cardiff Model is a unique violence surveillance system and intervention that involves data sharing and violence prevention planning between law enforcement and the medical field. Anonymized data on assaults from emergency and police departments (EDs; PDs) are combined to detail assault incidents and "hotspots." Data are discussed by a multidisciplinary consortium, which develops and implements a data-informed violence prevention action plan that includes behavioral, environmental, and policy changes to impact violence. Model actions led to decreases in injurious assaults and this model is now statutory in the United Kingdom.

The Cardiff Model has never been translated to the U.S. and would require an investigation within our health care system and in different geographical and population contexts. This study investigated the feasibility of essential Cardiff Model Components in order to refine study procedures and situate this community to request further funds for full model implementation.

As part of this study, researchers collected a number of feasibility measures from ED and study staff to evaluate the feasibility of translating included model components. Geospatial and statistical analyses investigated the added benefit of the combined ED, PD and Emergency Medical Services (EMS) data.

The study contains 1 SPSS data files (CHW Data_1.1.15 to 7.31.16.sav (n=748; 14 variables)), 1 STATA data file (nurse survey data.dta (n=43; 26 variables)), a text document (Nurse Survey_Qualitative data.txt), and 1 excel file (CHW Incidents_Block level data only.xlsx).

Time period: 1984-01-01--2006-01-01

The research team collected data on homicide, robbery, and assault offending from 1984-2006 for youth 13 to 24 years of age in 91 of the 100 largest cities in the United States (based on the 1980 Census) from various existing data sources. Data on youth homicide perpetration were acquired from the Supplementary Homicide Reports (SHR) and data on nonlethal youth violence (robbery and assault) were obtained from the Uniform Crime Reports (UCR). Annual homicide, robbery, and assault arrest rates per 100,000 age-specific populations (i.e., 13 to 17 and 18 to 24 year olds) were calculated by year for each city in the study. Data on city characteristics were derived from several sources including the County and City Data Books, SHR, and the Vital Statistics Multiple Cause of Death File. The research team constructed a dataset representing lethal and nonlethal offending at the city level for 91 cities over the 23-year period from 1984 to 2006, resulting in 2,093 city year observations.

Justifying Violence: Attitudes of American Men, 1969 (ICPSR 3504)

Released/updated on: 2005-11-04

Geographic coverage: United States

This study contains data on the attitudes of 1,374 American men aged 16-64 toward violence in 1969. The study was undertaken to examine the levels of violence that can be viewed as justified to bring about social control or social change. Also emphasized were the role of the respondents' personal values, their definitions of violence, and their identification with the groups involved in violence. Some of the open-ended questions in the structured interview probed the respondents' general concerns, their attitudes toward violence, and their views on the causes of and ways of preventing violence. In questions grouped into categories of "violence for social control" and "violence for social change", respondents were asked to react to situations involving protests and other disturbances such as hoodlum gang disturbances, students' protests, and Black protest demonstrations. Repondents' opinions were sought on the appropriate police actions in these situations and the frequency with which certain control measures should be utilized. Respondents were also asked in three different situations whether they believed change could be effected without action involving property damage or injury, or if change could only be effected with protests in which some people were killed. Demographic variables describe age, sex, date of birth, nationality, occupation, education, religion, and family income. A supplementary sample of Black men is also included in this study in order to permit separate analysis on the basis of race.

Time period: 2015-09-01--2015-12-01, 2016-09-01--2016-12-01

The Bureau of Justice Statistics (BJS) entered into a cooperative agreement with Westat to develop and evaluate a lower-cost, subnational companion survey of victimization as one piece of the subnational estimates program. The Local-Area Crime Survey (LACS) was fielded in 2015 and 2016 and is intended for use by states, municipalities, or other jurisdictions and entities to assess levels and trends in public safety. The LACS is modeled in part after the National Crime Victimization Survey (NCVS), conducted for BJS by the U.S. Census Bureau. One of the two major statistical programs on crime produced by the U.S. Department of Justice, the NCVS is the nation's primary source of information about criminal victimization, whether reported or not reported to police. The core NCVS methodology includes a mix of in-person and telephone interviews with household members age 12 and older selected from an area probability sample to produce reliable national-level estimates. As another part of the subnational estimates program, BJS worked with the Census Bureau to enhance and reallocate the NCVS sample to support subnational estimates for the 22 most populous states and potentially substate areas within those states. For the most part, this direct estimation component of the program will not support estimates at the local level. See the NCVS Subnational Estimates webpage on the BJS website for more information.

The goals of this research were to (1) develop and test a relatively inexpensive survey design (2) that could be administered by local jurisdictions or their vendors (3) to produce cross-jurisdiction estimates and estimates of change over time within jurisdictions that may be compared with similar estimates using NCVS data. In addition to questions about victimization experiences, the LACS included questions about perceptions of community safety and police efficacy. The rationale for including these items was that they were relevant to all households, not just victims. The hope was that these items would increase survey response rates as non-victims would have important questions to answer. The LACS served as a platform for assessing the value of these questions for the planned NCVS instrument redesign. For more information, see the NCVS Instrument Redesign webpage on the BJS website.

Geographic coverage: Oregon, United States

Time period: 1990-01-01--1999-01-01

This study explored the implementation and impact of Measure 11 (passed by Oregon voters in 1994), which imposed long mandatory prison terms for 16 designated violent and sex-related offenses, prohibited "earned time," and provided for mandatory waiver of youthful offenders to adult court. Measure 11 penalties were longer than those imposed under sentencing guidelines. Juveniles aged 15 years or older were also subject to the measure. The researchers addressed the implementation and impact of the measure on prosecution, sentencing, and convictions, both statewide and in three separate counties based on the Oregon Criminal Justice Commission (OCJC) data and the Oregon Department of Corrections (DOC) data. Variables include offender characteristics, plea trial information, number of convictions, prison term for convictions, severity of offense, M11-eligible and alternate offense, and description of most severe offense.

Measuring Crime Rates of Prisoners in Colorado, 1988-1989 (ICPSR 9989)

Released/updated on: 2005-11-04

Geographic coverage: United States, Colorado

Time period: 1988-07-01--1989-12-01

In the late 1970s, the Rand Corporation pioneered a method of collecting crime rate statistics. They obtained reports of offending behavior--types and frequencies of crimes committed--directly from offenders serving prison sentences. The current study extends this research by exploring the extent to which variation in the methodological approach affects prisoners' self-reports of criminal activity. If the crime rates reported in this survey remained constant across methods, perhaps one of the new techniques developed would be easier and/or less expensive to administer. Also, the self-reported offending rate data for female offenders in this collection represents the first time such data has been collected for females. Male and female prisoners recently admitted to the Diagnostic Unit of the Colorado Department of Corrections were selected for participation in the study. Prisoners were given one of two different survey instruments, referred to as the long form and short form. Both questionnaires dealt with the number of times respondents committed each of eight types of crimes during a 12-month measurement period. The crimes of interest were burglary, robbery, assault, theft, auto theft, forgery/credit card and check-writing crimes, fraud, and drug dealing. The long form of the instrument focused on juvenile and adult criminal activity and covered the offender's childhood and family. It also contained questions about the offender's rap sheet as one of the bases for validating the self-reported data. The crime count sections of the long form contained questions about motivation, initiative, whether the offender usually acted alone or with others, and if the crimes recorded included crimes against people he or she knew. Long-form data are given in Part 1. The short form of the survey had fewer or no questions compared with the long form on areas such as the respondent's rap sheet, the number of crimes committed as a juvenile, the number of times the respondent was on probation or parole, the respondent's childhood experiences, and the respondent's perception of his criminal career. These data are contained in Part 2. In addition, the surveys were administered under different conditions of confidentiality. Prisoners given what were called "confidential" interviews had their names identified with the survey. Those interviewed under conditions of anonymity did not have their names associated with the survey. The short forms were all administered anonymously, while the long forms were either anonymous or confidential. In addition to the surveys, data were collected from official records, which are presented in Part 3. The official record data collection form was designed to collect detailed criminal history information, particularly during the measurement period identified in the questionnaires, plus a number of demographic and drug-use items. This information, when compared with the self-reported offense data from the measurement period in both the short and long forms, allows a validity analysis to be performed.

Mental Disorder and Violent Crime: A 20-Year Cohort Study in New York State, 1968-1988 (ICPSR 9978)

Released/updated on: 1996-02-09

Geographic coverage: New York City, United States, New York (state)

Time period: 1968-01-01--1988-01-01

The objectives of this study were (1) to compare long-term patterns of violent crime for mentally disordered patients and for prison inmates, and (2) to evaluate the predictive validity of a diagnosis of schizophrenia for subsequent arrests for violent crimes. For purposes of this data collection, violent crimes were defined as including murder, manslaughter, rape, assault, kidnapping, and sodomy. The study analyzed individual state mental hospital patients and inmates of state prisons in New York State over a 20-year span. In the process of obtaining information regarding the individuals, three different areas were focused on: hospital, incarceration, and arrest histories. Variables for hospital histories include inpatient hospitalizations, admission and discharge dates, legal status for all state hospitals through 1988, primary diagnosis for target and most recent admissions, and placements in New York State Department of Correctional Services mental hospitals. Incarceration history variables include time spent in adult state prisons, incarcerations through 1988, and dates of release (including re-entry to community on parole, outright release, or escape). Arrest histories include information on the subject's first adult arrest through 1988 (only the most serious charge for each incident is recorded) and out-of-state arrests, when available. Demographic variables include age, race, and date of birth.

Mentally Disordered Offenders in Pursuit of Celebrities and Politicians (ICPSR 6007)

Released/updated on: 2006-03-30

Geographic coverage: United States

These data were collected to develop a means of identifying those individuals most likely to be dangerous to others because of their pursuit of public figures. Another objective of the study was to gather detailed quantitative information on harassing and threatening communications to public figures and to determine what aspects of written communications are predictive of future behavior. Based on the fact that each attack by a mentally disordered person in which an American public figure was wounded had occurred in connection with a physical approach within 100 yards, the investigators reasoned that accurate predictions of such physical approaches could serve as proxies for the less feasible task of accurate prediction of attacks. The investigators used information from case files of subjects who had pursued two groups of public figures, politicians and celebrities. The data were drawn from the records of the United States Capitol Police and a prominent Los Angeles-based security consulting firm, Gavin de Becker, Inc. Information was gathered from letters and other communications of the subjects, as well as any other sources available, such as police records or descriptions of what occurred during interviews. The data include demographic information such as sex, age, race, marital status, religion, and education, family history information, background information such as school and work records, military history, criminal history, number of communications made, number of threats made, information about subjects' physical appearance, psychological and emotional evaluations, information on travel/mobility patterns, and approaches made.

Missing Data in the Uniform Crime Reports (UCR), 1977-2000 [United States] (ICPSR 32061)

Released/updated on: 2012-11-26

Geographic coverage: United States

Time period: 1977-01-01--2000-01-01

This study reexamined and recoded missing data in the Uniform Crime Reports (UCR) for the years 1977 to 2000 for all police agencies in the United States. The principal investigator conducted a data cleaning of 20,067 Originating Agency Identifiers (ORIs) contained within the Offenses-Known UCR data from 1977 to 2000. Data cleaning involved performing agency name checks and creating new numerical codes for different types of missing data including missing data codes that identify whether a record was aggregated to a particular month, whether no data were reported (true missing), if more than one index crime was missing, if a particular index crime (motor vehicle theft, larceny, burglary, assault, robbery, rape, murder) was missing, researcher assigned missing value codes according to the "rule of 20", outlier values, whether an ORI was covered by another agency, and whether an agency did not exist during a particular time period.

National Crime Surveys: Cities Attitude Sub-Sample, 1972-1975 (ICPSR 7663)

Released/updated on: 2006-01-12

Geographic coverage: United States

Time period: 1972-01-01--1975-01-01

This subsample of the national crime surveys consists of data on personal and household victimization for persons aged 12 and older in 26 major United States cities in the period 1972-1975. The National Crime Surveys were designed by the Bureau of Justice Statistics to meet three primary objectives: (1) to develop detailed information about the victims and consequences of crime, (2) to estimate the numbers and types of crimes not reported to police, and (3) to provide uniform measures of selected types of crimes in order to permit reliable comparisons over time and between areas. The surveys provide measures of victimization on the basis of six crimes (including attempts): rape, robbery, assault, burglary, larceny, and motor vehicle theft. The total National Crime Survey employed two distinct samples: a National Sample, and a Cities Sample. The cities sample consists of information about victimization in 26 major United States cities. The data collection was conducted by the United States Census Bureau, initial processing of the data and documentation was performed by the Data Use and Access Laboratories (DUALabs), and subsequent processing was performed by the ICPSR under grants from the Bureau of Justice Statistics (BJS). This Cities Attitude Sub-Sample study also includes information on personal attitudes and perceptions of crime and the police, the fear of crime, and the effect of this fear on behavioral patterns such as choice of shopping areas and places of entertainment. Data are provided on reasons for respondents' choice of neighborhood, and feelings about neighborhood, crime, personal safety, and the local police. Also specified are date, type, place, and nature of the incidents, injuries suffered, hospital treatment and medical expenses incurred, offender's personal profile, relationship of offender to victim, property stolen and value, items recovered and value, insurance coverage, and police report and reasons if incident was not reported to the police. Demographic items cover age, sex, marital status, race, ethnicity, education, employment, family income, and previous residence and reasons for migrating. This subsample is a one-half random sample of the Complete Sample, NATIONAL CRIME SURVEYS: CITIES, 1972-1975 (ICPSR 7658), in which an attitude questionnaire was administered. The subsample contains data from the same 26 cities that were used in the Complete Sample.

National Crime Surveys: Redesign Data: Peoria Record Check Study (ICPSR 8669)

Released/updated on: 2006-03-30

Geographic coverage: United States

The purpose of this study was to measure criminal activity in the United States based on survey reports of crime victims. In the study two different questionnaire forms were used in order to assess which provided better responses. One form was very lengthy and asked detailed questions about each household, person, and incident. The second form was much shorter and asked very generalized questions. The data collection was an attempt to find alternative methods of sampling, interviewing, designing questionnaires, managing data, and reporting results. Detailed information is provided on household characteristics and other characteristics of the respondents, as well as on crime incidents, including burglary, vandalism, assault, and rape.

National Crime Surveys: Reverse Record Check Studies: Washington, DC, San Jose, and Baltimore, 1970-1971 (ICPSR 8693)

Released/updated on: 2006-01-18

Geographic coverage: District of Columbia, Puerto Rico, Baltimore, United States, Maryland

Time period: 1970-01-01--1971-01-01

These surveys were part of a series of pretests conducted during the early 1970s to reveal problems associated with doing a nationwide study on victimization. They were done to determine the most effective reference period to use when questioning respondents in order to gain the fullest and most reliable information, to measure the degree to which respondents move incidents occurring outside the reference period into that period when questioned, and to explore the possibility of identifying incidents by a few broad general questions as opposed to a series of more specific probing questions.
