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.

Alaska Sexual Assault Nurse Examiner (SANE) Data, 1996-2006 (ICPSR 28367)

Released/updated on: 2012-10-05

Geographic coverage: Fairbanks, Kotzebue, United States, Kodiak, Alaska, Anchorage, Homer, Soldotna, Bethel, Nome

Time period: 1996-01-01--2006-01-01

This project examined the characteristics of sexual assault victimizations in Alaska, as observed and recorded by sexual assault nurse examiners in Anchorage, Kodiak, Bethel, Soldotna, Nome, Fairbanks, Homer, and Kotzebue. The sample utilized for this study included all sexual assault nurse examinations conducted in Anchorage from 1996 to 2004, in Bethel and Fairbanks in 2005 and 2006, and in Homer, Kodiak, Kotzebue, Nome, and Soldotna in 2005. A total of 1,699 examinations were collected. More specifically, the information contains demographic characteristics of patients, pre-assault patient characteristics, assault characteristics, post assault characteristics, exam characteristics and findings, and suspect characteristics. Demographic characteristics of patients include gender, race / ethnicity, and age, whether the patient was disabled, and whether the patient reported being homeless. Pre-assault characteristics included whether the patient reported engaging in consensual sexual activity within three days prior to the assault and information on the location of the initial contact with the suspect. Assault characteristics included information on the location of the assault, methods employed by the suspect, the patients' condition at the time of the assault, the patients' use of drugs and alcohol, and a detailed description of the assault itself. This detailed description included the patient's position during the assault, whether condoms and lubricants had been used, whether ejaculation had occurred, and an inventory of 17 different sexual acts. Post-assault characteristics included information on post-assault actions taken by the patient, whether the patient engaged in consensual sexual activity between the time of the assault to the examination, and the time elapsed from the assault to the examination. Exam characteristics and findings included information on whether the exam was completed, the type of exam that was conducted, the patients' behavioral and emotional state during the exam, whether the patient required emergency medical care, whether the presence of sperm was documented, whether patients tested positive for sexually transmitted infections or other genital infections, whether the patient was pregnant, and whether injuries were documented. Injury characteristics included descriptions of both non-genital and genital injury. A total of 108 indicators of non-genital injury were captured. These included nine possible injuries (i.e., bruising, redness, abrasions, lacerations, swelling, fractures, bite marks, pain, and other) to 12 possible sites (i.e., head/face, mouth, neck, shoulders, arms, hands, chest, abdomen, back, buttocks/hips, legs, and feet). A total of 60 indicators of genital injury were also captured. These included four possible injuries (i.e., bruising, abrasions, lacerations, and tenderness) to 15 possible sites (i.e., mons pubis, labia majora, labia minora, labia majora / minora junction, clitoral hood, clitoris, periurethra, hymen, fossa navicularis, posterior fourchette, perineum, vaginal walls, cervix, anus, and rectum). Suspect characteristics included the number of suspects, whether the identity of the suspect was known, demographic characteristics (gender, race/ethnicity, and age), whether the suspect had used alcohol or drugs, and the relationship between the patient and the suspect. In addition to providing detailed information from sexual assault nurse examinations, the data also include three indicators of legal resolutions - whether cases were referred for prosecution, whether cases were accepted for prosecution, and whether cases resulted in a conviction. Data on legal resolutions are only available for 1,229 cases examined from 1999 to 2005.

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

Time period: 1983-01-01--1984-01-01

This data collection compares a sample of persons arrested for offenses related to crack cocaine with a sample arrested for offenses related to powdered cocaine. The collection is one of two parts of a study designed to examine the characteristics of crack users and sellers, the impact of large numbers of crack-related offenders on the criminal justice system, and their effects on drug treatment and community programs. Official arrest records and supplementary data bases are used to analyze the official arrest, conviction, and incarceration histories of powdered cocaine and crack defendants. Questions addressed by the collection include: (1) How are defendants charged with crack-related offenses different from defendants charged with offenses related to powdered cocaine? (2) Is there a difference between the ways the criminal justice system handles crack offenders and powdered cocaine offenders in pretrial detention, charges filed, case dispositions, and sentencing? (3) How do the criminal careers of crack offenders compare with the criminal careers of powdered cocaine offenders, especially in terms of total arrest rates, frequencies of nondrug crimes, and frequencies of violent crimes? (4) Is violence more strongly associated with crack dealing than with powdered cocaine dealing? and (5) How does the developmental history of powdered cocaine sales and possession compare with the history of crack sales and possession? Variables include demographic information such as gender, residence, and race, arrest, conviction, and incarceration histories, prior criminal record, community ties, and court outcomes of the arrests.

Crime Control Effects of Sentencing in Essex County, New Jersey, 1976-1997 (ICPSR 2857)

Released/updated on: 2005-11-04

Geographic coverage: United States, New Jersey

Time period: 1976-01-01--1997-01-01

This study was undertaken to examine the ways in which different felony sanctions impact the future behavior of felony offenders. The study sought to determine whether the following made a difference in subsequent criminal behavior: (1) sentences of confinement, (2) the length of sentence (both the sentence imposed and that which was actually served), and (3) sentences of probation combined with jail ("split" sentences), or combined with fines, restitution, or other alternative sanctions. Data were collected from questionnaires completed by 18 judges of the Essex County, New Jersey, courts and by probation staff. Follow-up data were collected from official records provided by probation, jail, prison, and parole case files. Follow-up data were also collected from the following official records: (1) the New Jersey Offender-Based Transaction System Computerized Criminal History, (2) the New Jersey Department of Corrections Offender-Based Correctional Information System, (3) the United States Department of Justice Interstate Identification Index, (4) the National Crime Information Center Wanted Persons File, (5) the New Jersey PROMIS/GAVEL Prosecutors Case Tracking System, and (6) administrative record files of the New Jersey Department of Corrections. Variables in the data file include the most serious offense charge, most serious offense of conviction, dimension of conviction, offense type (person, property, social order, fraud, or drug offense), number of prior probations, number of probation revocations, number of prior jail and prison terms, mitigating and aggravating factors affecting the sentence, type of sentence, special conditions of probation, fines and restitutions imposed, minimum and maximum incarceration terms (in months), history of drug offenses, type of drugs used, probation and parole violations, total number of prior arrests and prior convictions, and longest arrest-free period after first arrest. The type of post-sentence offense, dimension, disposition charge, sentence, and date of arrest are provided for arresting events and charge episodes 1 through 108 for any offender. For up to 43 arrest events (for any offender), the date of lockup and date of exit from confinement are provided. The file also includes recommendations made by prosecutors and probation officers, and judges' ratings (on a scale of one to nine) with respect to the likelihood of an offender committing future property crimes, crimes against persons, or any crime. Judges also rated the arrest record length, conviction record length, and social stability of each offender. Retribution points, incapacitation points, and specific deterrence points assigned by the judges complete the file. Demographic variables include the race and sex of each convicted offender, and the age of the offender at first conviction.

Evaluating a Driving While Intoxicated (DWI) Night Drug Court in Las Cruces, New Mexico, 1997-1998 (ICPSR 3186)

Released/updated on: 2006-01-18

Geographic coverage: Las Cruces, United States, New Mexico

The purpose of this study was twofold. First, researchers wanted to assess the benefits of the driving while intoxicated (DWI) drug court established in the Las Cruces, New Mexico, Municipal Court in an effort to determine its future viability. This was accomplished by examining the behaviors and attitudes of three groups of convicted drunk-drivers and determining the extent to which these groups were different or similar. The three groups included: (1) non-alcoholic first- and second-time offenders (non-alcoholic offenders), (2) alcoholic first- and second-time DWI offenders (alcoholic offenders), and (3) chronic three-time (or more) DWI offenders (chronic offenders). The second purpose of this study was to explore police officers' attitudes toward court-based treatment programs for DWI offenders, while examining the distinguishing characteristics between police officers who support court-based programs for drunk drivers and those who are less likely to support such sanctions. Data for Part 1, Drug Court Survey Data, were collected using a survey questionnaire distributed to non-alcoholic, alcoholic, and chronic offenders. Part 1 variables include blood alcohol level, jail time, total number of prior arrests and convictions, the level of support from the respondents' family and friends, and whether the respondent thought DWI was wrong, could cause injury, or could ruin lives. Respondents were also asked whether they acted spontaneously in general, took risks, found trouble exciting, ever assaulted anyone, ever destroyed property, ever extorted money, ever sold or used drugs, thought lying or stealing was OK, ever stole a car, attempted breaking and entering, or had been a victim of extortion. Demographic variables for Part 1 include the age, gender, race, and marital status of each respondent. Data for Part 2, Police Officer Survey Data, were collected using a survey questionnaire designed to capture what police officers knew about the DWI Drug Court, where they learned about it, and what factors accounted for their attitudes toward the program. Variables for Part 2 include police officers' responses to whether DWI court was effective, whether DWI laws were successful, the perceived effect of mandatory jail time versus treatment alone, major problems seen with DWI policies, if DWI was considered dangerous, and how the officer had learned or been briefed about the drug court. Other variables include the number of DWI arrests, and whether respondents believed that reforms weaken police power, that DWI caused more work for them, that citizens have bad attitudes, that the public has too many rights, and that stiffer penalties for DWI offenders were more successful.

Federally Prosecuted Commercial Sexual Exploitation of Children (CSEC) Cases, United States, 1998-2005 (ICPSR 26722)

Released/updated on: 2019-10-29

Geographic coverage: United States

Time period: 1998-01-01--2005-01-01

To increase understanding of the prosecution of Commercial Sexual Exploitation of Children and Youth (CSEC) offenders, the Urban Institute, a non-partisan social and economic policy research organization, along with Polaris Project, an anti-human trafficking organization based in the United States and Japan, were awarded a cooperative agreement from the Office of Juvenile Justice and Delinquency Prevention (OJJDP) to conduct a 12-month study on CSEC in the United States. The purpose of this research was to conduct a national analysis of federal prosecutions of CSEC-related cases from 1998 through 2005, in order to answer the following four research questions:

Is the United States enforcing existing federal laws related to CSEC?
What are key features of successfully prosecuted CSEC cases? What factors predict convictions in cases? What factors predict sentence length?
Have the U.S. courts increased penalties associated with sexual crimes against children?
What, if any, are the effects of CSEC legislation on service providers who work with these victims?

The data collection includes three datasets: (Dataset 1) Base Cohort File with 7,696 cases for 50 variables, (Dataset 2) Commercial Sexual Exploitation of Children (CSEC) Defendants in cases filed in U.S. Court with 7,696 cases for 100 variables, and (Dataset 3) Suspects in Criminal Matters Investigated and Concluded by U.S. Attorneys Dataset with 13,819 cases for 14 variables.

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 Prisoner Litigation Reform, 1992-2000 [United States] (ICPSR 20354)

Released/updated on: 2008-04-10

Geographic coverage: United States

Time period: 1992-04-01--2000-12-01

In 1996, the United States Congress enacted two policies to regulate the use of the legal system by state prisoners. They were the Prisoner Litigation Reform Act (PLRA) and the Antiterrorism and Effective Death Penalty Act (AEDPA). The purpose of this research project was to examine whether the PLRA and the AEDPA had their intended effects of reducing the number of Section 1983 lawsuits and habeas corpus petitions, respectively, at both the national and circuit court levels. The researchers obtained data, from the Research and Statistics Division of the Administrative Office of the United States Courts, on the number of civil rights suits and the number of habeas corpus petitions filed by state prisoners in district courts from April 1992 to December 2000. These data were organized into monthly increments. Dataset 1, Civil Rights Suits Filed, contains 105 cases, and Dataset 2, Habeas Corpus Petitions Filed, also contains 105 cases. The trends in civil rights suits filed (Dataset 1) and habeas corpus petitions filed (Dataset 2) were measured by the number of petitions filed per 10,000 state prisoners. Filing rates were measured at the level of district courts, grouped together by the circuit court that has jurisdiction over them.

Variables in Dataset 1, Civil Rights Suits Filed, include filing date and the number of civil rights suits filed per 10,000 state prisoners at the national level as well as for district courts within each of the 11 circuits and the District of Columbia. An intervention flag variable is also included. Variables in Dataset 2, Habeas Corpus Petitions Filed, include filing date and the number of habeas corpus petitions filed per 10,000 state prisoners at the national level, as well as for district courts within each of the 11 circuits and the District of Columbia. A pulse flag variable and two intervention flag variables are also included.

Impact of Rape Reform Legislation in Six Major Urban Jurisdictions in the United States, 1970-1985 (ICPSR 6923)

Released/updated on: 2006-03-30

Geographic coverage: United States

Time period: 1970-01-01--1985-01-01

Despite the fact that most states enacted rape reform legislation by the mid-1980s, empirical research on the effect of these laws was conducted in only four states and for a limited time span following the reform. The purpose of this study was to provide both increased breadth and depth of information about the effect of the rape law changes and the legal issues that surround them. Statistical data on all rape cases between 1970 and 1985 in Atlanta, Chicago, Detroit, Houston, Philadelphia, and Washington, DC, were collected from court records. Monthly time-series analyses were used to assess the impact of the reforms on rape reporting, indictments, convictions, incarcerations, and sentences. The study also sought to determine if particular changes, or particular combinations of changes, affected the case processing and disposition of sexual assault cases and whether the effect of the reforms varied with the comprehensiveness of the changes. In each jurisdiction, data were collected on all forcible rape cases for which an indictment or information was filed. In addition to forcible rape, other felony sexual assaults that did not involve children were included. The names and definitions of these crimes varied from jurisdiction to jurisdiction. To compare the pattern of rape reports with general crime trends, reports of robbery and felony assaults during the same general time period were also obtained from the Uniform Crime Reports (UCR) from the Federal Bureau of Investigation when available. For the adjudicated case data (Parts 1, 3, 5, 7, 9, and 11), variables include month and year of offense, indictment, disposition, four most serious offenses charged, total number of charges indicted, four most serious conviction charges, total number of conviction charges, type of disposition, type of sentence, and maximum jail or prison sentence. The time series data (Parts 2, 4, 6, 8, 10, and 12) provide year and month of indictment, total indictments for rape only and for all sex offenses, total convictions and incarcerations for all rape cases in the month, for those on the original rape charge, for all sex offenses in the month, and for those on the original sex offense charge, percents for each indictment, conviction, and incarceration category, the average maximum sentence for each incarceration category, and total police reports of forcible rape in the month. Interviews were also conducted in each site with judges, prosecutors, and defense attorneys, and this information is presented in Part 13. These interviewees were asked to rate the importance of various types of evidence in sexual assault cases and to respond to a series of six hypothetical cases in which evidence of the victim's past sexual history was at issue. Respondents were also presented with a hypothetical case for which some factors were varied to create 12 different scenarios, and they were asked to make a set of judgments about each. Interview data also include respondent's title, sex, race, age, number of years in office, and whether the respondent was in office before and/or after the reform.

The Principal Investigator sought answers to the following seven primary research questions:

How often is forensic evidence collected and analyzed and how is it used pre-arrest?
What are the outcomes of forensic evidence testing?
What is the effect of forensic evidence on arrest and charging?
How does forensic evidence affect the plea-bargaining process?
What effect does forensic evidence have on conviction and sentencing outcomes?
Does the turnaround time for analysis of forensic evidence have any impact on case disposition?
Does the institutional configuration of the crime laboratory have any effect on its productivity?

Data for the following types of forensic testing are included in this data collection: hair, fibers, glass, paint, gas chromatography / mass spectrometry (GC/MS), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy / energy dispersive x-ray spectroscopy (SEM/EDX), physical match, drug identification, toxicology, serology, combined DNA index system (CODIS), DNA short tandem repeat (Y-STR), blood pattern, test fire, and comparison scope.

Mandatory Drug offender Processing Data, 1986: Alaska, California, Iowa, Minnesota, Nebraska, New York, North Carolina, and Virginia (ICPSR 9420)

Released/updated on: 2006-01-12

Geographic coverage: North Carolina, Iowa, United States, Alaska, Minnesota, California, New York (state), Virginia, Nebraska

The National Consortium for Assessing Drug Control Initiatives, funded by the Bureau of Justice Assistance and coordinated by the Criminal Justice Statistics Association, collected drug offender processing data from eight states: Alaska, California, Iowa, Minnesota, Nebraska, New York, North Carolina, and Virginia. The purpose of the project was to track adult drug offenders from the point of entry into the criminal justice system (typically by arrest) through final court disposition, regardless of whether the offender was released without trial, acquitted, or convicted. These data allow researchers to examine how the criminal justice system processes drug offenders, to measure the changing volume of drug offenders moving through the different segments of the criminal justice system, to calculate processing time intervals between major decision-making events, and to assess the changing structure of the drug offender population. For purposes of this project, a drug offender was defined as any person who had been charged with a felony drug offense. The data are structured into six segments pertaining to (1) record identification, (2) the offender (date of birth, sex, race, ethnic origin), (3) arrest information (date of arrest, age at arrest, arrest charge code), (4) prosecution information (filed offense code and level, prosecution disposition and date), (5) court disposition information (disposition offense and level, court disposition, final disposition date, final pleading, type of trial), and (6) sentencing information (sentence and sentence date, sentence minimum and maximum). Also included are elapsed time variables. The unit of analysis is the felony drug offender.

Massachusetts Superior Court Files, 1859-1959 (ICPSR 7776)

Released/updated on: 2010-05-14

Geographic coverage: United States, Massachusetts

Time period: 1859-01-01--1959-01-01

This dataset contains data about case records created between 1859-1959 in the Massachusetts Superior Court (and its predecessors) for two Massachusetts counties. Part 1 contains data for 1,952 criminal cases with 52 descriptive variables, including: type of crime, year crime was committed, pleas, sentences, appeals, size of file, and demographic characteristics of victim and defendant (e.g., gender, status, residence, and occupation). Eighteen variables describe and rate each case's historical interest. Part 2 contains data on 1,968 civil (law, equity, and divorce) cases, with 82 descriptive variables, such as: relationship between parties, type of complaint, relief sought, disposition, relief granted, number of claims, damages awarded, size of file, and demographic characteristics of plaintiff and defendant (e.g., gender, status, residence, and occupation). Ten variables describe and rate each case's historical interest. In both data files, criteria for historical interest coding include: (1) inherent interest, such as offenses that are not routine (e.g., white-collar crimes, sexual crimes, and serious felonies), parties who are inherently interesting (e.g., famous persons, institutional defendants, and law enforcement personnel), and legal proceedings that are inherently interesting (e.g., alleged violations of prosecutorial or judicial discretion), (2) contexts that are inherently interesting, and (3) extraordinary documentation, such as those that shed light on the legal system (e.g., pardons or letters from citizens' committees), shed light on social history (e.g., the testimony of a woman who moved to the city and inadvertently ended up in a brothel), provide legal/procedural information (e.g., the details of search or a technical challenge to an indictment), and describe public or political history (e.g., milk inspection or zoning laws).

Michigan Study of Life After Prison, Administrative Data on 2003 Cohort of Michigan Parolees (ICPSR 32681)

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 files available with this collection and consult the investigator(s) if further information is needed.

The Michigan Study of Life After Prison examined the association between neighborhood context and outcomes related to employment and recidivism among the cohort of former prisoners released on parole from Michigan state prisons in one calendar year (2003), controlling for pre-incarceration neighborhood context, local labor market conditions, and a large set of individual characteristics. The primary goals of this study were to answer two questions: (1) "Are ex-offenders who are released to more disadvantaged neighborhoods (those with greater poverty, unemployment, residential turnover, etc.) more likely to recidivate?" (2) "Are ex-offenders who are released to more disadvantaged neighborhoods less likely to gain stable employment?" This research sought to supplement available literature on prisoner reentry and criminal desistance, which the researchers posit existing literature has largely ignored the role that neighborhoods play in shaping the recidivism and employment of returning prisoners.

Geographic coverage: United States

Time period: 1987-01-01--1998-01-01

This collection contains information on federal criminal cases sentenced under the Sentencing Guidelines and Policy Statements of the Sentencing Reform Act of 1984. The data files include all cases received by the United States Sentencing Commission that had sentencing dates between November 1, 1987, and September 30, 1998, and were assessed as constitutional. Constitutionality compares each case's sentencing date, circuit, district, and judge to provide uniformity in reporting the cases. The cases are categorized either as New Law, with all offenses occurring after the November 1, 1987, guidelines, or as Mixed Law, with at least one count occurring after the guideline effectiveness date and other counts prior to the guidelines. The Cross-Reference Data files contain data for guidelines that are cross-referenced or that are considered to be underlying guidelines.

In 1999, the United States Sentencing Commission added more variables from its databases to this collection, so the data are now provided in two files. Part 1, Main Data File, includes the most important variables for each case, such as defendant's age, criminal history points, armed criminal status, case disposition, sentence, and fines applied. Part 2, Supplemental Data File, contains additional variables involving multiple guideline computation and count-based statutes. For a more detailed discussion of the two files, users should consult the codebook.
