Incapacitation Effects of Incarcerating Drug Offenders: Longitudinal Arrest Histories of Adults Arrested in Washington, DC, 1985-1986 (ICPSR 2741)
Released/updated on: 2000-07-27
Geographic coverage: District of Columbia, United States
Time period: 1985-07-01--1986-06-01
This study examined differences in criminal career parameters that determine the potential incapacitative effects of alternative sentencing policies directed at drug-involved offenders. In particular, the researchers explored three key aspects of offenders' criminal careers: participation, frequency of offending, and termination rates from active offending. The study focused on differences in levels of serious offending by drug-using and nonusing drug offenders compared to drug-using and nonusing predatory offenders. Longitudinal arrest data for a sample of arrestees were collected to characterize the offending patterns of drug-using and nonusing drug offenders and predatory offenders. The sample was drawn from adults arrested in Washington, DC, on any charge from July 1, 1985, to June 30, 1986. Data were collected from case files maintained by the Washington, DC, Pretrial Services Agency for 883 arrestees and 5,387 arrests. Previous and subsequent arrests of the same individual were linked to form an arrest history. Within the sample of arrestees, three main types of offenders were distinguished based on offense charge at target arrest: (1) drug offenders, (2) predatory offenders (persons charged with robbery or burglary), and (3) all others. This study focused on the first two groups and distinguished drug users from non-users based on the results of a urine drug screen administered following the target arrest. Variables regarding arrests include date of arrest, drug test result, charges filed, disposition date, disposition type, and sentence length imposed. Demographic variables include race, sex, and place of birth.

Violent Offending by Drug Users: Longitudinal Arrest Histories of Adults Arrested in Washington, DC, 1985-1986 (ICPSR 6254)
Released/updated on: 1996-01-22
Geographic coverage: District of Columbia, United States
Time period: 1985-07-01--1986-06-01
This data collection effort examined the influence of drug use on three key aspects of offenders' criminal careers in violence: participation, frequency of offending, and termination rate. A random sample of arrestees was taken from those arrested in Washington, DC, during the period July 1, 1985, to June 6, 1986. The sample was stratified to overrepresent groups other than Black males. Drug use was determined by urinalysis results at the time of arrest, as contrasted with previous studies that relied on self-reports of drug use. The research addresses the following questions: (1) Does drug use have an influence on participation in violent criminal activity? (2) Does drug use influence the frequency of violent offending? (3) Is there a difference in the types and rates of violent offending between drug-using offenders who use stimulants and those who use depressants? Variables regarding arrests include date of arrest, drug test result, charges filed, disposition date, disposition type, and sentence length imposed. Demographic variables include race, sex, birthdate, and place of birth.

Evaluating the Incapacitative Benefits of Incarcerating Drug Offenders in Los Angeles and Maricopa [Arizona] Counties, 1986 and 1990 (ICPSR 6374)
Released/updated on: 2006-01-12
Geographic coverage: United States, California, Arizona
The objective of this study was to examine the observable offending patterns of recent and past drug offenders to assess the crime control potential associated with recent increases in the incarceration of drug offenders. The periods examined were 1986 (representing the second half of the 1980s, when dramatic shifts toward increasing incarceration of drug offenders first became evident), and 1990 (after escalating sentences were well under way). Convicted offenders were the focus, since these cases are most directly affected by changes in imprisonment policies, particularly provisions for mandatory prison terms. Offending patterns of convicted and imprisoned drug offenders were contrasted to patterns of convicted robbers and burglars, both in and out of prison. The researchers used data from the National Judicial Reporting Program (NJRP), sponsored by the U.S. Department of Justice, Bureau of Justice Statistics (BJS), for information on the court processing of individual felony convictions. The National Association of Criminal Justice Planners (NACJP), which maintains data for the approximately 50 counties included in the NJRP, was contracted to determine the counties to be sampled (Los Angeles County and Maricopa County in Arizona were chosen) and to provide individual criminal histories. Variables include number of arrests for robbery, violent crimes, property crimes, and other felonies, number of drug arrests, number of misdemeanor arrests, rate of violent, property, robbery, weapons, other felony, drug, and misdemeanor arrests, offense type (drug trafficking, drug possession, robbery, and burglary), total number of incarcerations, total number of convictions, whether sentenced to prison, jail, or probation, incarceration sentence in months, sex, race, and age at sampled conviction, and age at first arrest (starting at age 17).

Recidivism of Prisoners Released in 1994 (ICPSR 3355)
Released/updated on: 2014-12-05
Geographic coverage: North Carolina, Oregon, New York, United States, Minnesota, California, Florida, Delaware, New Jersey, Michigan, Illinois, Texas, Ohio, Virginia, Maryland, Arizona
Time period: 1994-01-01--1997-01-01
RECIDIVISM OF PRISONERS RELEASED IN 1994 is a database containing information on each of 38,624 sampled prisoners released from prisons in 15 states in 1994 and tracked for three years following their release. The majority of the database consists of information on each released prisoner's entire officially recorded criminal history (before and after the 1994 release). Sources for criminal history information are state and FBI automated RAP ("Records of Arrests and Prosecutions") sheets, which contain records of arrests, adjudications, and sentences. The study is the second major recidivism study conducted by the Bureau of Justice Statistics. The first study, RECIDIVISM AMONG RELEASED PRISONERS, 1983: [UNITED STATES] (ICPSR 8875), tracked over 16,000 prisoners released in 11 states in 1983 for three years. These two studies are the closest approximation to "national" recidivism studies in the United States. They are distinguished by their large sample size (over 16,000 released prisoners in the first study, 38,624 in the second), geographic breadth of coverage (11 states in the first study, 15 in the second), length of prospective tracking (three years from date of release in both studies), ability to track the movement of released prisoners across state boundaries (both studies), and multiple measures of recidivism (both studies). Demographic data include race, ethnicity, sex, and date of birth.

Prosecuting Adolescents in Juvenile and Criminal Jurisdictions in Selected Counties in New Jersey and New York, 1992-1993 (ICPSR 3976)
Released/updated on: 2005-11-04
Geographic coverage: New York, United States, New Jersey
Time period: 1992-01-01--1993-01-01
A different model of justice is assumed to be reflected in the prosecution of adolescents in juvenile jurisdictions compared to criminal jurisdictions, with a juvenile justice model in the juvenile jurisdiction and a criminal justice model in the criminal jurisdiction. These two models of justice are believed to be very different from one another across three dimensions: formality of case processing, evaluation of defendants, and punishment. This research project compared the prosecution and punishment of adolescent felony offenders in the New Jersey juvenile jurisdiction and the New York criminal jurisdiction to determine whether these two models of justice varied across the two jurisdiction types. Data from this collection were used by the researcher only to examine the dimension of punishment severity across jurisdiction types and across courts within each jurisdiction type. Data were collected on comparable cases of adolescent felony offenders from counties in New Jersey and New York. Due to the very different boundaries between juvenile and criminal jurisdictions in these adjacent states, the data include cases (matched by offense and offender age) in New Jersey's juvenile jurisdiction and New York's criminal jurisdiction. Cases of 15- and 16-year-old defendants who had been charged with aggravated assault, robbery, or burglary in three counties of New Jersey and three counties of New York City in 1992 and 1993 were sampled. Variables include offender characteristics, such as age at offense, sex, race, and ethnicity, offense characteristics, court action and sentencing information, state, and county.

Juvenile Defendants in Criminal Courts (JDCC): Survey of 40 Counties in the United States, 1998 (ICPSR 3750)
Released/updated on: 2003-09-25
Geographic coverage: United States
This is an independent sample of juvenile defendants drawn from the State Court Processing Statistics (SCPS) for 1998 (see ICPSR 2038). SCPS 1998 tracked felony cases filed in May 1998 until final disposition or until one year had elapsed from the date of filing. SCPS 1998 presents data on felony cases filed in approximately 40 of the nation's 75 most populous counties in 1998. These 75 counties account for more than a third of the United States population and approximately half of all reported crimes. The cases from these 40 jurisdictions were weighted to represent all felony filings during the month of May in the 75 most populous counties. Data were collected on arrest charges, demographic characteristics, criminal history, pretrial release and detention, adjudication, and sentencing. Within each sampled site, data were gathered on each juvenile felony case. Cases were tracked through adjudication or for up to one year. The source used to identify the upper age for juveniles and the filing mechanism appropriate to each state was the OJJDP publication, Trying Juveniles as Adults in Criminal Court: An Analysis of State Transfer Provisions (December 1998).

Boston Police Department Domestic Violence Research Project, 1993-1994 (ICPSR 6483)
Released/updated on: 2006-01-12
Geographic coverage: United States, Massachusetts, Boston
The Domestic Violence Research Project was a pilot study designed to examine the dynamics of domestic violence within two of the ten police districts that comprise the city of Boston. The objectives were to collect data on domestic violence in greater detail than previously possible, conduct various analyses on this information, and determine how the findings could best be used to improve the police, prosecutorial, and social service responses to domestic violence. Data for 1993 are a stratified random sample of reported domestic violence incidents occurring throughout the year. The sample represents approximately 27 percent of the domestic violence incidents reported in 1993 for the two districts studied, B3 and D4. The 1994 data include all reported incidents occurring in the two districts during the period May to July. After the incident selection process was completed, data were collected from police incident reports, follow-up investigation reports, criminal history reports, and court dockets. Variables include arrest offenses, time of incident, location of incident, witnesses (including children), nature and extent of injuries, drug and alcohol use, history of similar incidents, whether there were restraining orders in effect, and basic demographic information on victims and offenders. Criminal history information was coded into five distinct categories: (1) violent offenses, (2) nonviolent offenses, (3) domestic violence offenses, (4) drug/alcohol offenses, and (5) firearms offenses.

White-Collar Criminal Careers, 1976-1978: Federal Judicial Districts (ICPSR 6540)
Released/updated on: 2006-03-30
Geographic coverage: United States
Time period: 1976-01-01--1978-01-01
This study examined the criminal careers of 1,331 offenders convicted of white-collar crimes in the United States District Courts to assess the relative effectiveness of court-imposed prison sanctions in preventing or modifying future criminal behavior. The white-collar crime event that was the central focus of this study, the "criterion" offense, provided the standard point of entry for sample members. Researchers for this study supplemented the data collected by Wheeler et al. in their 1988 study (NATURE AND SANCTIONING OF WHITE COLLAR CRIME, 1976-1978: FEDERAL JUDICIAL DISTRICTS [ICPSR 8989]) with criminal history data subsequent to the criterion offense through to 1990. As in the 1988 study, white-collar crime was considered to include economic offenses committed through the use of some combination of fraud, deception, or collusion. Eight federal offenses were examined: antitrust, securities fraud, mail and wire fraud, false claims and statements, credit fraud, bank embezzlement, income tax fraud, and bribery. Arrests were chosen as the major measure of criminal conduct. The data contain information coded from Federal Bureau of Investigation (FBI) criminal history records ("rap sheets") for a set of offenders convicted of white-collar crimes in federal courts in fiscal years 1976 to 1978. The seven federal judicial districts from which the sample was drawn were central California, northern Georgia, northern Illinois, Maryland, southern New York, northern Texas, and western Washington. To correct for a bias that can be introduced when desistance from criminality is confused with the death of the offender, the researchers examined the National Death Index (NDI) data to identify offenders who had died between the date of sentencing for the criterion offense and when data collection began for this study in 1990. This data collection contains three types of records. The first record type (Part 1, Summary Data) contains summary and descriptive information about the offender's rap sheet as a whole. Variables include dates of first entry and last entry on the rap sheet, number of separate crimes on the rap sheet, whether the criterion crime was listed on the rap sheet, whether the rap sheet listed crimes prior to or subsequent to the criterion crime, and date of death of offender. The second and third record types are provided in one data file (Part 2, Event and Event Interim Data). The second record type contains information about each crime event on the rap sheet. Variables include custody status of offender at arrest, type of arresting agency, state of arrest, date of arrest, number of charges for each arrest, number of charges resulting in no formal charges filed, number of charges dismissed, number of charges for white-collar crimes, type of sanction, length of definite sentence, probation sentence, and suspended probation sentence, amount of fines, amount of court costs, and restitution ordered, first, second, and third offense charged, arrest and court disposition for each charge, and date of disposition. The third record type contains information about the interim period between events or between the final event and the end of the follow-up period. Variables include date of first, second, and third incarceration, date discharged or transferred from each incarceration, custody/supervision status at each incarceration, total number of prisons, jails, or other institutions resided in during the interval, final custody/supervision status and date discharged from incarceration for the interval, dates parole and probation started and expired, if parole or probation terms were changed or completed, amount of fines, court costs, and restitution paid, whether the conviction was overturned during the interval, and date the conviction was overturned. A single offender has as many of record types two and three as were needed to code the entire rap sheet.

Impact of Community Policing at the Street Level: An Observational Study in Richmond, Virginia, 1992 (ICPSR 2612)
Released/updated on: 2006-03-30
This study's purpose was twofold: to investigate the nature of police patrol work in a community policing context and to field-test data collection instruments designed for systematic social observation. The project, conducted in Richmond, Virginia, where its police department was in the third year of a five-year plan to implement community policing, was designed as a case study of one police department's experience with community policing, focusing on officers in the patrol division. A team of eight researchers conducted observations with the police officers in the spring and summer of 1992. A total of 120 officers were observed during 125 observation sessions. Observers accompanied officers throughout their regular work shifts, taking brief field notes on officers' activities and encounters with the public. All of an observed officer's time during the shift was accounted for by either encounters or activities. Within 15 hours of the completion of the ridealong, the observer prepared a detailed narrative account of events that occurred during the ridealong and coded key items associated with these events. The study generated five nested quantitative datasets that can be linked by common variables. Part 1, Ridealong Data, provides information pertinent to the 125 observation sessions or "rides." Part 2, Activity Data, focuses on 5,576 activities conducted by officers when not engaged in encounters. Data in Part 3, Encounter Data, describe 1,098 encounters with citizens during the ridealongs. An encounter was defined as a communication between officers and citizens that took over one minute, involved more than three verbal exchanges between an officer and a citizen, or involved significant physical contact between the officer and citizen. Part 4, Citizen Data, provides data relevant to each of the 1,630 citizens engaged by police in the encounters. Some encounters involved more than one citizen. Part 5, Arrest Data, was constructed by merging Parts 1, 3, and 4, and provides information on 451 encounters that occurred during the ridealongs in which the citizen was suspected of some criminal mischief. All identification variables in this collection were created by the researchers for this project. Variables from Part 1 include date, start time, end time, unit, and beat assignment of the observation session, and the primary officer's and secondary officer's sex, race/ethnicity, years as an officer, months assigned to precinct and beat, hours of community policing training, and general orientation to community policing. Variables in Part 2 specify the time the activity began and ended, who initiated the activity, type, location, and visibility of the activity, involvement of the officer's supervisor during the activity, and if the activity involved problem-solving, or meeting with citizens or other community organizations. Part 3 variables include time encounter began and ended, who initiated the encounter, primary and secondary officer's energy level and mood before the encounter, problem as radioed by dispatcher, and problem as it appeared at the beginning of the encounter and at the end of the encounter. Information on the location of the encounter includes percent of time at initial location, visibility, officer's prior knowledge of the initial location, and if the officer anticipated violence at the scene. Additional variables focus on the presence of a supervisor, other police officers, service personnel, bystanders, and participants, if the officer filed or intended to file a report, if the officer engaged in problem-solving, and factors that influenced the officer's actions. Citizen information in Part 4 includes sex, age, and race/ethnicity of the citizen, role in the encounter, if the citizen appeared to be of low income, under the use of alcohol or drugs, or appeared to have a mental disorder or physical injury or illness, if the citizen was representing an establishment, if the citizen lived, worked, or owned property in the police beat, and if the citizen had a weapon. Also presented are various aspects of the police-citizen interaction, such as evidence considered by the officer, requests and responses to each other, and changes in actions during the encounter. Variables in Part 5 record the officer's orientation toward community policing, if the suspect was arrested or cited, if the offense was serious or drug-related, amount of evidence, if the victim requested that the suspect be arrested, if the victim was white, Black, and of low income, and if the suspect represented an organization. Information on the suspect includes gender, race, sobriety level, if of low income, if 19 years old or less, if actively resistant, if the officer knew the suspect adversarially, and if the suspect demonstrated conflict with others. Some items were recoded for the particular analyses for which the Arrest Data were constructed.

Early Identification of the Serious Habitual Juvenile Offender Using a Birth Cohort in Philadelphia, 1958-1984 (ICPSR 2312)
Released/updated on: 2008-04-04
Geographic coverage: United States, Philadelphia, Pennsylvania
Time period: 1958-01-01--1984-01-01
Beginning in the mid-1980s, the Office of Juvenile Justice and Delinquency Prevention (OJJDP) funded the creation of Habitual Offender Units (HOUs) in 13 cities. HOUs were created to prosecute habitual juvenile offenders by deploying the most experienced attorneys to handle these cases from start to finish. By targeting the earliest points in the career sequence of the juvenile offenders, the greatest number of serious offenses can potentially be averted. Selection criteria to qualify for priority prosecution by an HOU usually encompassed one or more generic components relating to aspects of a juvenile's present and prior offense record. In Philadelphia, to be designated a serious habitual offender and to qualify for priority prosecution by the HOU, a youth had to have two or more prior adjudications or open cases for specific felonies, as well as a current arrest for a specified felony. The first three police contacts in a Philadelphia juvenile offender's record were of special interest because they included the earliest point (i.e., the third contact) at which a youth could be prosecuted in the Philadelphia HOU, under their selection criteria. The main objectives of this study were to determine how well the selection criteria identified serious habitual offenders and which variables, reflecting HOU selection criteria, criminal histories, and personal characteristics, were most strongly and consistently related to the frequency and seriousness of future juvenile and young adult offending. To accomplish this, an assessment was conducted using a group of juveniles born in 1958 whose criminal career outcomes were already known. Applying the HOU selection criteria to this group made it possible to determine the extent to which the criteria identified future habitual offending. Data for the analyses were obtained from a birth cohort of Black and white males born in 1958 who resided in Philadelphia from their 10th through their 18th birthdays. Criminal careers represent police contacts for the juvenile years and arrests for the young adult years, for which police contacts and arrests are synonymous. The 40 dependent variables were computed using 5 different criminal career aspects for 4 crime type groups for 2 age intervals. The data also contain various dummy variables related to prior offenses, including type of offense, number of prior offenses, disposition of the offenses, age at first prior offense, seriousness of first prior offense, weapon used, and whether it was a gang-related offense. Dummy variables pertaining to the current offenses include type of offense, number of crime categories, number of charges, number of offenders, gender, race, and age of offenders, type of intimidation used, weapons used, number of crime victims, gender, race, and age of victims, type of injury to victim, type of victimization, characteristics of offense site, type of complainant, and police response. Percentile of the offender's socioeconomic status is also provided. Continuous variables include age at first prior offense, age at most recent prior offense, age at current offense, and average age of victims.

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.

Geographic coverage: Oregon, Milwaukee, United States, Portland (Oregon), Florida, Wisconsin, Miami
Time period: 1979-01-01--1982-01-01
This data collection effort was designed to assess the effects of different types of supervised pretrial release (SPR). Four major types of effects were examined: (1) defendants' behaviors while awaiting trial (failure to appear and arrests for new offenses), (2) the costs of SPR to victims and the criminal justice system, (3) pretrial release practices, and (4) jail populations. This study provides detailed information for a selected group of defendants awaiting trial on criminal histories and arrests while awaiting trial. Data are also available on services provided between arrest and disposition. The study produced four different data sets. The first, Supervised Release Information System (SRIS), contains intake information on current arrest, criminal record, socio-economic status, ties with the community, contact with mental health and substance abuse facilities, and pretrial release decisions. The release section of this data base contains information on services provided, intensity of supervision, termination from program, personal characteristics at termination, criminal charges at disposition, and new charges resulting from arrests while under pretrial status. The Arrest Data Set includes variables on type and number of crimes committed by SPR defendants, property costs to victims, personal injury costs, and court disposition for each offense. The Retrospective Data Set supplies variables on charges filed and method of release, personal characteristics, length of pretrial incarceration, bail, whether the defendant was rebooked during the pretrial period, charge at disposition, sentence, total court appearances, and total failures to appear in court (FTAs). The Jail Population Data Set contains monthly counts of jail population and average daily population.

Prison Crowding and Forced Releases in Illinois, 1979-1982 (ICPSR 8921)
Released/updated on: 2006-03-30
Time period: 1979-07-01--1982-12-01
These data were collected in the Illinois prison system where, in response to a prison overcrowding crisis, approximately two-thirds of the inmates released by the Illinois Department of Corrections (IDOC) were discharged prior to serving their expected sentences. This study was designed to evaluate the effects of an early release program on prisoners, prison populations, offense rates, local criminal justice systems, and the general public. The files contain extensive Federal Bureau of Investigation arrest history information and other personal and social indicators describing inmates released from the state prison system. Data are available for three comparison groups: (1) a sample of prisoners who served their regular sentences prior to the "forced release" program, (2) a group that served regular sentences after implementation of the program, and (3) a group of inmates who were released early under the program (i.e., before serving their full sentences). The "inmate jacket file," which is the comprehensive institutional file maintained for all inmates, contains variables for each inmate on social and personal characteristics, criminal history, risk scales, court decisions for each offense, institutional conduct, prior release and return records, method of release, condition of supervision, and parole violation records. The arrest file includes variables that describe the type and number of charges at arrest, case disposition of each charge, probation length, incarceration length, admission and release dates, and release type.

Murder Cases in 33 Large Urban Counties in the United States, 1988 (ICPSR 9907)
Released/updated on: 2006-01-12
Geographic coverage: United States
This study was conducted in an effort to better understand the circumstances surrounding murder cases in large urban areas. To evaluate the 75 largest counties in the nation, 33 counties were chosen. The ranking of these counties was based on a combination of crime data and population data. The criteria for including a case on a roster from which cases would be sampled was that (1) one or more defendants must have been arrested for murder and (2) the case must have been adjudicated during 1988. These cases were a sample of about half of all those in the 33 counties studied that had a murder charge brought to the prosecutors in 1988, or earlier, and that were disposed during 1988. When statistically weighted, the sample cases represent a total of 9,576 murder defendants in the nation's 75 largest counties. Demographic information on victims and defendants includes sex, date of birth, area of residence, and occupation. Variables are also provided on the circumstances of the crime, including the relationship between the victim and the defendant, the type of weapon used, the time of death, and the number of victims.
