Arrests As Communications to Criminals in St. Louis, 1970, 1972-1982 (ICPSR 9998)

Released/updated on: 2006-01-12
Geographic coverage: United States, Missouri, St. Louis
Time period: 1972-01-01--1982-01-01
This data collection was designed to assess the deterrent effects over time of police sanctioning activity, specifically that of arrests. Arrest and crime report data were collected from the St. Louis Police Department and divided into two categories: all Uniform Crime Reporting Program Part I crime reports, including arrests, and Part I felony arrests. The police department also generated geographical "x" and "y" coordinates corresponding to the longitude and latitude where each crime and arrest took place. Part 1 of this collection contains data on all reports made to police regarding Part I felony crimes from 1970 to 1982 (excluding 1971). Parts 2-13 contain the yearly data that were concatenated into one file for Part 1. Variables in Parts 2-13 include offense code, census tract, police district, police area, city block, date of crime, time crime occurred, value of property taken, and "x" and "y" coordinates of crime and arrest locations. Part 14 contains data on all Part I felony arrests. Included is information on offense charged, the marital status, sex, and race of the person arrested, census tract of arrest, and "x" and "y" coordinates.

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.

Charlotte [North Carolina] Spouse Assault Replication Project, 1987-1989 (ICPSR 6114)

Released/updated on: 2006-07-13
Geographic coverage: North Carolina, Charlotte, United States
Time period: 1987-08-01--1989-06-01
This study is a replication and extension of an experiment conducted in Minneapolis (MINNEAPOLIS INTERVENTION PROJECT, 1986-1987 [ICPSR 9808]) to test the efficacy of three types of police response to spouse abuse. Three experimental treatments were employed: (1) advising and possibly separating the couple, (2) issuing a citation (an order to appear in court to answer specific charges) to the offender, and (3) arresting the offender. The main focus of the project concerned whether arrest is the most effective law enforcement response for deterring recidivism of spouse abusers. Cases were randomly assigned to one of the three treatments and were followed for at least six months to determine whether recidivism occurred. Measures of recidivism were obtained through official police records and victim interviews. Cases that met the following eligibility guidelines were included in the project: (1) a call involving a misdemeanor offense committed by a male offender aged 18 or over against a female victim aged 18 or over who were spouses, (2) ex-spouses, (3) cohabitants, or (4) ex-cohabitants. Also, both suspect and victim had to be present when officers arrived at the scene. Victims were interviewed twice. The first interview occurred shortly after the "presenting incident," the incident that initiated a call for police assistance. This initial interview focused on episodes of abuse that occurred between the time of the presenting incident and the day of the initial interview. In particular, detailed data were gathered on the nature of physical violence directed against the victim, the history of the victim's marital and cohabitating relationships, the nature of the presenting incident prior to the arrival of the police, the actual actions taken by the police at the scene, post-incident separations and reunions of the victim and the offender, recidivism since the presenting incident, the victim's previous abuse history, alcohol and drug use of both the victim and the offender, and the victim's help-seeking actions. Questions were asked regarding whether the offender had threatened to hurt the victim, actually hurt or tried to hurt the victim, threatened to hurt any member of the family, actually hurt or tried to hurt any member of the family, threatened to damage property, or actually damaged any property. In addition, criminal histories and arrest data for the six-month period subsequent to the presenting incident were collected for offenders. A follow-up interview was conducted approximately six months after the presenting incident and focused primarily on recidivism since the initial interview. Arrest recidivism was defined as any arrest for any subsequent offense by the same offender against the same victim committed within six months of the presenting incident. Victims were asked to estimate how often each type of victimization had occurred and to answer more detailed questions on the first and most recent incidents of victimization.

Criminal Recidivism in a Large Cohort of Offenders Released from Prison in Florida, 2004-2008 (ICPSR 27781)

Released/updated on: 2010-07-29
Geographic coverage: United States, Florida
Time period: 2004-01-01--2008-01-01
The purpose of the study was to quantify the effect of the embrace of DNA technology on offender behavior. In particular, researchers examined whether an offender's knowledge that their DNA profile was entered into a database deterred them from offending in the future and if probative effects resulted from DNA sampling. The researchers coded information using criminal history records and data from Florida's DNA database, both of which are maintained by the Florida Department of Law Enforcement (FDLE), and also utilized court docket information acquired through the Florida Department of Corrections (FDOC) to create a dataset of 156,702 cases involving offenders released from the FDOC in the state of Florida between January 1996 and December 2004. The data contain a total of 50 variables. Major categories of variables include demographic variables regarding the offender, descriptive variables relating to the initial crime committed by the offender, and time-specific variables regarding cases of recidivism.

Deinstitutionalization of Status Offenders: a Study of Intervention Practices for Youth in Seven Cities in the United States, 1987-1991 (ICPSR 6039)

Released/updated on: 2005-11-04
Geographic coverage: United States
Time period: 1987-01-01--1991-01-01
This data collection focuses on status offenders--those juveniles who commit acts (such as running away, habitual truancy, and possession of alcohol) that are forbidden to minors but not to adults. The purpose of this study was to connect legislative intent, service delivery systems, and youth responses in order to provide guidelines for future status offender legislation and practice. In the selection of sampling sites, three categories of intervention philosophy were represented: (1) deterrence, which recommends sanctions and control through the juvenile justice system, (2) treatment, which recommends emotional adjustment strategies through the community mental health system, and (3) normalization, which recommends little or no professional response. Respondents from youth service agencies in seven cities in the United States were asked about service delivery system characteristics (such as types of referral sources, how often they were used, and length of client service period), organizational characteristics (such as public versus private auspices, sources of funding, and educational level of staff), and youth characteristics (such as family situation, school status, and educational attainment of principal adults in the home). Demographic variables for status offenders included gender, race, age, and type of residence. Interviews with youths were also conducted and included a self-concept scale, by which youths could categorize themselves as delinquent, disturbed, and/or conforming. The units of analysis for this study are the individual and the youth service agency.

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.

Deterrent Effects of Punishment on Crime Rates, 1959-1960 (ICPSR 7716)

Released/updated on: 1992-02-16
Geographic coverage: United States
Time period: 1959-01-01--1960-01-01
The study contains cross-section data on the relationship between aggregate levels of punishment and crime rates. It examines deterrent effects of punishment on seven Federal Bureau of Investigation (FBI) index crimes: murder, rape, assault, larceny, robbery, burglary, and auto theft, committed in 1960 in 47 states of the United States (excluded were New Jersey, Alaska, and Hawaii). For each state, the data include variables for the reported crime rates for each of the seven index crimes. For each of the index crimes, there are two sanction variables included: the probability of prison commitment and the average time served by those sentenced (severity of punishment). There are 11 socioeconomic variables, including family income, income distribution, unemployment rate for urban males in the age groups 14-24 and 35-39, labor force participation rate, educational level, percentage of young males in population, percentage of non-white young males living in the population, percentage of population living in Standard Metropolitan Statistical Areas, sex ratio, and place of occurrence. The data also include per capita police expenditures for 1959 and 1960. A related data collection is PARTICIPATION IN ILLEGITIMATE ACTIVITIES: EHRLICH REVISITED, 1960 (ICPSR 8677). It provides alternative model specifications and estimations.

Deterrent Effects of the New York Juvenile Offender Law, 1974-1984 (ICPSR 9324)

Released/updated on: 2005-11-04
Geographic coverage: New York City, United States, New York (state), Philadelphia, Pennsylvania
Time period: 1974-01-01--1984-01-01
This data collection was designed to assess the effects of the New York Juvenile Offender Law on the rate of violent crime committed by juveniles. The data were collected to estimate the deterrent effects of the law and to permit the use of an interrupted time-series model to gauge the effects of intervention. The deterrent effects of the law are assessed on five types of violent offenses over a post-intervention period of 75 months using two comparison time series to control for temporal and geographical characteristics. One time series pertains to the monthly juvenile arrests of 16- to 19-year-olds in New York City, and the other covers monthly arrests of juveniles aged 13 to 15 years in Philadelphia, Pennsylvania, the control jurisdiction. Included in the collection are variables concerning the monthly rates of violent juvenile arrests for homicide, rape, assault, arson, and robbery for the two juvenile cohorts. These time series data were compiled from records of individual police jurisdictions that reported monthly arrests to the Uniform Crime Reporting Division of the Federal Bureau of Investigation.

Deterring Drug Use With Intensive Probation in New Jersey, 1989-1990 (ICPSR 9919)

Released/updated on: 2002-06-27
Geographic coverage: United States, New Jersey
Time period: 1989-01-01--1990-01-01
These data were collected to measure the degree to which subjective deterrence and rational choice are effective in reducing drug-use recidivism rates. Baseline interviews were conducted with participants upon entering a drug rehabilitation program in New Jersey. Under the terms of this program, which was an alternative to prison, any incident of drug use occurring during the rehabilitation period would result in the participant's returning to prison. Follow-up interviews were conducted when the participant either had a drug/alcohol use relapse or successfully completed a year in the program without a drug-use incident. Baseline interviews included questions about criminal and drug-use history, as well as initial reactions to the drug rehabilitation program. Follow-up interviews probed for participants' feelings about the drug rehabilitation program experience. Further questions concerned participants' failure or success at staying away from drugs or alcohol.

Domestic Violence Experience in Omaha, Nebraska, 1986-1987 (ICPSR 9481)

Released/updated on: 2006-07-24
Geographic coverage: Omaha, United States, Nebraska
Time period: 1986-01-01--1987-01-01
The purpose of this data collection was to corroborate the findings of SPECIFIC DETERRENT EFFECTS OF ARREST FOR DOMESTIC ASSAULT: MINNEAPOLIS, 1981-1982 (ICPSR 8250) that arrest is an effective deterrent against continued domestic assaults. The data addressed the following questions: (1) To what extent does arrest decrease the likelihood of continued violence, as assessed by the victim? (2) To what extent does arrest decrease the likelihood of continued complaints of crime, as assessed by police records? (3) What are the differences in arrest recidivism between cases that involved arrest versus cases that involved mediation, separation, warrant issued, or no warrant issued? Domestic violence cases in three sectors of Omaha, Nebraska, meeting established eligibility criteria, were assigned to one of five experimental treatments: mediation, separation, arrest, warrant issued, or no warrant issued. Data for victim reports were collected from three interviews with the victims conducted one week, six months, and 12 months after the domestic violence incident. Arrest, charge, and complaint data were collected on the suspects at six- and twelve-month intervals following the original domestic violence incident. The investigators used arrest recidivism, continued complaints of crime, and victim reports of repeated violence (fear of injury, pushing/hitting, and physical injury) as outcome measures to assess the extent to which treatments prevented subsequent conflicts. Other variables include victim's level of fear, self-esteem, locus of control, and welfare dependency, changes in the relationship between suspect and victim, extent of the victim's injury, and extent of drug use by the victim and the suspect. Demographic variables include race, age, sex, income, occupational status, and marital status.

Drugs and Police Response: Survey of Public Housing Residents in Denver, Colorado, 1989-1990 (ICPSR 6482)

Released/updated on: 1995-08-16
Geographic coverage: United States, Colorado, Denver
Time period: 1989-01-01--1990-01-01
This data collection is the result of an evaluation of the NEPHU program, conducted by the Police Foundation under the sponsorship of the National Institute of Justice (NIJ). In August 1989, the Bureau of Justice Assistance supported a grant in Denver, Colorado, to establish a special Narcotics Enforcement in Public Housing Unit (NEPHU) within the Denver Police Department. The goal of the Denver NEPHU was to reduce the availability of narcotics in and around the city's public housing areas by increasing drug arrests. NEPHU's six full-time officers made investigations and gathered intelligence leading to on-street arrests and search warrants. The unit also operated a special telephone Drug Hotline and met regularly with tenant councils in the developments to improve community relations. The program worked in cooperation with the Denver Housing Authority and the uniformed patrol division of the Denver Police Department, which increased levels of uniformed patrols to maintain high visibility in the project areas to deter conventional crime. Using a panel design, survey interviews were conducted with residents in the Quigg Newton and Curtis Park public housing units, focusing on events that occurred during the past six months. Respondents were interviewed during three time periods to examine the onset and persistence of any apparent program effects. In December 1989, interviews were completed with residents in 521 households. In June 1990, 422 respondents were interviewed in Wave 2. Wave 3 was conducted in December 1990 and included 423 respondents. In all, 642 individuals were interviewed, 283 of whom were interviewed for all three waves. Because of the evaluation's design, the data can be analyzed to reveal individual-level changes for the 283 respondents who were interviewed on all three occasions, and the data can also be used to determine a cross-section representation of the residents by including the 359 "new" persons interviewed during the course of the evaluation. Information collected includes years and months lived in the development, assessments of changes in the neighborhood, whether the respondent planned to stay in the development, interactions among residents, awareness of anti-drug programs, ranking of various problems in the development, concerns and reports of being a victim of various crimes, perceived safety of the development, assessment of drug use and availability, assessment of police activity and visibility, and personal contacts with police. The unit of analysis is the individual.

Effect of Procedural Justice in Spouse Assault in Milwaukee, Wisconsin, 1987-1989 (ICPSR 20343)

Released/updated on: 2008-04-17
Geographic coverage: Milwaukee, United States, Wisconsin
Time period: 1987-01-01--1989-01-01
The purpose of the research project was to examine the extent to which the perception of procedural fairness by suspects arrested for spouse assault effectively inhibited their subsequent violence. The data for this study were collected for the MILWAUKEE DOMESTIC VIOLENCE EXPERIMENT, 1987-1989 (ICPSR 9966), which was conducted from April 1987 to August 1988. In this experiment, all cases of misdemeanor domestic battery where probable cause to arrest existed were randomly assigned to one of three conditions: (1) warning with no arrest, (2) arrest with a brief detention period (average of 3 hours), and (3) arrest with a longer detention period (average of 11 hours). Variables include demographic and background information, as well as descriptive variables pertaining to the domestic violence incident.

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.

Milwaukee Domestic Violence Experiment, 1987-1989 (ICPSR 9966)

Released/updated on: 2006-01-12
Geographic coverage: Milwaukee, United States
Time period: 1987-01-01--1989-01-01
This study represents a modified replication of the Minneapolis Domestic Violence Experiment (SPECIFIC DETERRENT EFFECTS OF ARREST FOR DOMESTIC ASSAULT: MINNEAPOLIS, 1981-1982 [ICPSR 8250]). The Minneapolis study found arrest to be an effective deterrent against repeat domestic violence. The two key purposes of the current study were (1) to examine the possible differences in reactions to arrest, and (2) to compare the effects of short and long incarceration associated with arrest. Research protocol involved 35 patrol officers in four Milwaukee police districts screening domestic violence cases for eligibility, then calling police headquarters to request a randomly-assigned disposition. The three possible randomly assigned dispositions were (1) Code 1, which consisted of arrest and at least one night in jail, unless the suspect posted bond, (2) Code 2, which consisted of arrest and immediate release on recognizance from the booking area at police headquarters, or as soon as possible, and (3) Code 3, which consisted of a standard Miranda-style script warning read by police to both suspect and victim. A battered women's shelter hotline system provided the primary measurement of the frequency of violence by the same suspects both before and after each case leading to a randomized police action. Other forms of measurement included arrests of the suspect both before and after the offense, as well as offenses against the same victim. Initial victim interviews were attempted within one month after the first 900 incidents were compiled. A second victim interview was attempted six months after the incident for all 1,200 cases. Data collected for this study included detailed data on each of the 1,200 randomized events, less detailed data on an additional 854 cases found ineligible, "pipeline" data on the frequency of domestic violence in the four Milwaukee police districts, official measures of prior and subsequent domestic violence for both suspects and victims, interviews of arrested suspects for eligible and ineligible cases, criminal justice system dispositions of the randomized arrests, results of urinalysis tests of drug and alcohol use for some arrestees, and log attempts to obtain interviews from suspects and victims. Demographic variables include victim and suspect age, race, education, employment status, and marital status. Additional information obtained includes victim-offender relationships, alcohol and drug use during incident, substance of conflict, nature of victim injury and medical treatment as reported by police and victims, characteristics of suspects in the Code 1 and 2 arrest groups, victim and suspect reports of who called police, and victim and suspect versions of speed of police response.

Perceptual Deterrence and Desistance from Crime: A Study of Repetitive Serious Property Offenders in Tennessee, 1987-1988 (ICPSR 9971)

Released/updated on: 1999-11-19
Geographic coverage: United States, Tennessee
Time period: 1987-01-01--1988-01-01
For this data collection, offenders confined to prison were surveyed to examine the utility of deterrence theory variables as predictors of differential desistance from serious property crimes. The investigators also examined subjects' "criminal calculus," that is, their expectations of the likely gains and losses of further criminal behavior and the conditions under which they likely would commit further crimes. Specifically, the data explored whether decisions to commit crime are based on assessment of potential returns from alternate courses of action and the risk of legal sanctions. Sixty repeat offenders who had served one or more prison sentences were asked about their history of criminal activity, reasons for committing crimes, expectations of future criminal activities, and likely consequences of committing crimes. Data were collected in pre-release interviews in 1987 and 1988 as part of a larger study. Variables include age, education, age at first arrest, alcohol and drug use as a juvenile, as a young adult, and as a mature adult, past crimes, willingness to commit specific property crimes, reasons for being willing or unwilling to commit specific property crimes, expectations of arrest subsequent to actual crimes committed, and the likelihood of future criminal activity.

Re-examination of the Criminal Deterrent Effects of Capital Punishment in the United States, 1978-1998 (ICPSR 20040)

Released/updated on: 2008-01-31
Geographic coverage: United States
Time period: 1978-01-01--1998-01-01
The purpose of this study was to estimate the deterrent effect of capital punishment by employing a methodology that accounted for model uncertainty by integrating various studies into a single coherent analysis. First, this study replicated the results from two previous studies, Dezhbakhsh, Rubin and Shepherd (2003) and Donohue and Wolfers (2005), that draw on the same data. Second, the researchers implemented model averaging methods using standard frequentist estimators to take a weighted average of the findings across all possible models that could explain the effect of the difference in crime rates under alternate laws. Each model's effect was weighted based on its ability to explain the data. Variables used in this study included deterrence variables as well as various demographic and economic control variables.
