    Focused on the effect of economic resources and racial/ethnic composition on the change in crime rates from 1970-2004 in United States cities in metropolitan areas that experienced a large growth in population after World War II. A total of 352 cities in the following United States metropolitan areas were selected for this study: Atlanta, Dallas, Denver, Houston, Las Vegas, Miami, Orange County, Orlando, Phoenix, Riverside, San Bernardino, San Diego, Silicon Valley (Santa Clara), and Tampa/St. Petersburg. Selection was based on the fact that these areas developed during a similar time period and followed comparable development trajectories. In particular, these 14 areas, known as the "boomburbs" for their dramatic, post-World War II population growth, all faced issues relating to the rapid growth of tract-style housing and the subsequent development of low density, urban sprawls. Combined place-level data obtained from the United States Census with crime data from the Uniform Crime Reports for five categories of Type I crimes: aggravated assaults, robberies, murders, burglaries, and motor vehicle thefts. Contains a total of 247 variables pertaining to crime, economic resources, and race/ethnic composition.

  • Criminal Justice Drug Abuse Treatment Studies (CJ-DATS)
    Provides a comprehensive inquiry into the nature of programs & services provided to adult & juvenile offenders involved in the justice system in the United States. Participants included key criminal justice administrators, operations managers, and staff. The goals were to describe current drug treatment practices, policies, and delivery systems for offenders on probation or parole supervision, and in jails, prisons, and youth institutions; to examine agency structures, resources, and other organizational factors that may affect service delivery, including mission, leadership, climate, culture, and beliefs about rehabilitation versus punishment; and to assess coordination and integration across criminal justice agencies and between corrections and treatment systems. Items in the survey included: respondent characteristics, organizational characteristics, correctional programs characteristics (e.g., size, nature, etc.), substance abuse treatment programs characteristics, social networks/agencies collaboration, integration of services with other agencies, attitudes toward punishment and rehabilitation (personal values), organizational needs assessment, organizational culture and climate for treatment, cynicism toward change, organizational commitment to treatment, and perspectives on intradepartmental coordination.

  • Cross-National Comparison of Interagency Coordination Between Law Enforcement and Public Health

Primary goal was to produce promising practices that will help law enforcement and public health agencies improve interagency coordination related to terrorist threats, as well as other public health emergencies. Phase I of this study used the Surveillance System Inventory (SSI). The SSI is a database that documents and describes public health and public safety surveillance systems in the United States, the United Kingdom, Canada, and Ireland. The purpose of the SSI was to summarize the status of coordination between law enforcement and public health agencies across these systems, as well as to highlight potentially useful systems for coordination and dual-use integration.

  • Impact of Immigration on Ethnic-Specific Violence in Miami, Florida, 1997
    Does the rate of violent victimization differ across race and ethnic groups? In an effort to answer this question, this study sought to examine the violent victimization rate and the factors influencing ethnic-specific rates of violence in the city of Miami. Administrative data were obtained from the United States Bureau of the Census and the Miami Police Department Research Unit. For the groups of people identified as Afro Americans, Latinos, and Haitians, the numbers who were victims of aggravated assault and robbery in 1997 are included along with the assault and robbery rates for each group. The remaining variables are the percent of female-headed households, percent below poverty line, percent of young males out of the labor force and unemployed, residential instability, vacant and household instability, and the percent of 1980-1990 immigrants.

  • Impact of Legal Advocacy on Intimate Partner Homicide in the United States, 1976-1997
    Examined the impacts of jurisdictions' domestic violence policies on violent behavior of family members and intimate partners, on the likelihood that the police discovered an incident, and on the likelihood that the police made an arrest. Combined 2 datasets. Part 1 contains information on police, prosecution policies, and local victim services. Informants within the local agencies of the 50 largest cities in the United States were contacted and asked to complete a survey inventorying policies and activities by type and year of implementation. Data from completed surveys covered 48 cities from 1976 to 1996. Part 2 contains data on domestic violence laws. Data on state statutes from 1976 to 1997 that related to protection orders were collected by a legal expert for all 50 states and the District of Columbia.

    This report covers topics such as victimization, teacher injury, bullying and cyber-bullying, school conditions, fights, weapons, availability and student use of drugs and alcohol, student perceptions of personal safety at school, and criminal incidents at postsecondary institutions. Indicators of crime and safety are compared across different population subgroups and over time. Data on crimes that occur away from school are offered as a point of comparison where available.

  • Institutionalization Effect: The Impact of Mental Hospitalization and Imprisonment on Homicide in the United States, 1934 - 2001
    Explored the effect of imprisonment on violent crime rates prior to 1991. Previous research focused exclusively on rates of imprisonment, rather than using a measure that combines institutionalization in both prisons and mental hospitals. Using state-level panel-data regressions over the 68-year period from 1934 to 2001 and controlling for economic conditions, youth population rates, criminal justice enforcement, and demographic factors, this study found a large, robust, and statistically significant relationship between aggregated institutionalization (in mental hospitals and prisons) and homicide rates. This finding provided strong evidence of what should now be called an institutionalization effect -- rather than an imprisonment or incapacitation effect. Demographic information collected include national unemployment rates and institutional race and age composition.

  • Intercity Variation in Youth Homicide, Robbery, and Assault, 1984-2006
    Collected data on homicide, robbery, and assault offending 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.

The United States Sentencing Commission compiled from the Clerk of the Court of each court of appeals the final opinions and orders, both published and unpublished, in all criminal appeals for the time period surveyed. The Commission also collected habeas corpus decisions (although technically civil matters), because such cases often involve sentencing issues. Both the "case" and the "defendant" are used in this collection as units of analysis. Each "case" comprises individual records representing all codefendants participating in a consolidated appeal. Each defendant's record comprises the sentencing-related issues corresponding to that particular defendant.

  • Monitoring of Federal Criminal Sentences (1987+)
    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, 1995, 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.

  • Multi-Site Adult Drug Court Evaluation (MADCE), 2003-2009
    Included 23 drug courts and 6 comparison sites selected from 8 states across the country. The purpose was to: (1) Test whether drug courts reduce drug use, crime, and multiple other problems associated with drug abuse, in comparision with similar offenders not exposed to drug courts, (2) address how drug courts work and for whom by isolating key individual and program factors that make drug courts more or less effective in achieving their desired outcomes, (3) explain how offender attitudes and behaviors change when they are exposed to drug courts and how these changes help explain the effectiveness of drug court programs, and (4) examine whether drug courts generate cost savings. Offenders in all 29 sites were surveyed in 3 waves, at baseline, 6 months later, and 18 months after enrollment. The research comprises 3 major components: process evaluation, impact evaluation, and a cost-benefit analysis. The process evaluation describes how the 23 drug court sites vary in program eligibility, supervision, treatment, team collaboration, and other key policies and practices. The impact evaluation examines whether drug courts produce better outcomes than comparison sites and tests which court policies and offender attitudes might explain those effects. The cost-benefit analysis evaluates drug court costs and benefits.

  • Multi-User Database on the Attributes of United States Appeals Court Judges, 1801-2000
    Data on the personal, social, economic, career, and political attributes of judges who served on the United States Courts of Appeals from 1801 to 2000.

In addition, unique items are provided: the temporal sequence of prior career experiences, the timing of and reason for leaving the bench, gender, race and ethnicity, position numbering analogous to the scheme used for the Supreme Court, American Bar Association rating, and net worth (for judges who began service on the bench after 1978). The second objective of this project was to merge these data with a multi-user database on United States Courts of Appeals decisions. That database includes a unique identification number for each judge participating in a particular decision. The combined databases should enable scholars to explore: (1) intra- and inter-circuit fluctuation in the distribution of social background characteristics, (2) generational and presidential cohort variation in these attributes, and (3) state and partisan control of seats. The collection also facilitates the construction of models that examine the effects of personal attributes on decision-making, while controlling for the conditions above.

  • National Prosecutors Survey (1990+)
    Survey of chief prosecutors in state court systems. A chief prosecutor is an official, usually locally elected and typically with the title of district attorney or county attorney, who is in charge of a prosecutorial district made up of one or more counties, and who conducts or supervises the prosecution of felony cases in a state court system. Prosecutors in courts of limited jurisdiction, such as municipal prosecutors, were not included in the survey. The survey's purpose was to obtain detailed descriptive information on prosecutors' offices, as well as information on their policies and practices.

  • Offender Based Transaction Statistics (OBTS) (1979-1990)
    Information tracking adult offenders from the point of entry into the criminal justice system (typically by arrest), through final disposition, regardless of whether the offender is convicted or acquitted. Collected by individual states from existing data, the datasets include all cases that reached disposition during the calendar year. Using the individual adult offender as the unit for analysis, selected information is provided about the offender and his or her arrest, prosecution, and court disposition. Examples of variables included are arrest and level of arrest charge, date of arrest, charge filed by the prosecutor, prosecutor or grand jury disposition, type of counsel, type of trial, court disposition, sentence type, and minimum and maximum sentence length.

  • Program of Research on the Causes and Correlates of Delinquency Series
    Initiated to learn more about the root causes of juvenile delinquency and other problem behaviors. Comprises 3 coordinated longitudinal studies: Denver Youth Survey, Pittsburgh Youth Study and Rochester Youth Development Study. The 3 projects used a similar research design. All of the projects were longitudinal investigations involving repeated contacts with youth during a substantial portion of their developmental years. Researchers conducted regular face-to-face interviews with inner-city youth considered at high-risk for involvement in delinquency and drug abuse. Multiple perspectives on each child's development and behavior were obtained through interviews with the child's primary caretaker and, in two sites, school teachers. Administrative data from official agencies, including police, schools and social services was also collected. The 3 research teams worked together to ensure that certain core measures were identical across the sites, including self-reported delinquency and drug use; community and neighborhood characteristics; youth, family and peer variables; and arrest and judicial processing histories.

  • Project on Human Development in Chicago Neighborhoods. 1994+
    Large-scale, interdisciplinary study of how families, schools, and neighborhoods affect child and adolescent development. It was designed to advance the understanding of the developmental pathways of both positive and negative human social behaviors. In particular, the project examined the causes and pathways of juvenile delinquency, adult crime, substance abuse, and violence. Also provides a detailed look at the environments in which these social behaviors take place by collecting substantial amounts of data about urban Chicago, including its people, institutions, and resources.

  • Race and Drug Arrests: Specific Deterrence and Collateral Consequences, 1997-2009
    Examines several explanations for the observed racial/ethnic disparities in drug arrests, the consequences of drug arrest on subsequent drug offending and social bonding, and whether these consequences vary by race/ethnicity. The study is a secondary analysis of the National Longitudinal Survey of Youth 1997 (NLSY97).

  • Religious Freedom in the Courts, 1981-1997
    Derived from a content analysis of the The Religious Freedom Reporter (the Reporter), which is a journal published monthly by the Church-State Resource Center of the Norman Adrian Wiggins School of Law, Campbell University. The journal dates back to January 1981 and, as stated in the introductory preface to each issue, "seeks to provide comprehensive coverage of pending and decided cases, new legislation and regulations, law review articles and other resources related to religious freedom." Includes information from all levels of the judiciary. Has information on type of case (e.g., free exercise, first amendment and establishment), when the case was decided, level of court and the religion of the group or person who brought the case forward.

  • Research on Pathways to Desistance Series
    Multi-site, longitudinal study of serious adolescent offenders as they transition from adolescence into early adulthood. Between November, 2000 and January, 2003, 1,354 adjudicated youths from the juvenile and adult court systems in Maricopa County (Phoenix), Arizona (N = 654) and Philadelphia County, Pennsylvania (N = 700) were enrolled into the study. The enrolled youth were at least 14 years old and under 18 years old at the time of their committing offense and were found guilty of a serious offense (predominantly felonies, with a few exceptions for some misdemeanor property offenses, sexual assault, or weapons offenses). Each study participant was followed for a period of seven years past enrollment, with the end result a comprehensive picture of life changes in a wide array of areas over the course of this time. Sought to inform the ongoing debate in the juvenile justice system regarding the treatment and processing of serious adolescent offenders. The larger aim of the Pathways series is to improve decision-making by court and social service personnel and to clarify policy debates about alternatives for serious adolescent offenders. Additional datasets from the Pathways study will be released during 2013. These datasets will include official records information (e.g. re-arrest, placement), and monthly life-calendar data on a range of topics (e.g. school, work). These additional datasets will not be publicly available, but rather made available through ICPSR's restricted data access system.

  • School Survey on Crime and Safety (2000+) (SSOCS)
    Collects extensive crime & safety data from principals & school administrators of United States public schools. Can be used to examine the relationship between school characteristics and violent and serious violent crimes in primary schools, middle schools, high schools, and combined schools. Can also be used to assess what crime prevention programs, practices, and policies are used by schools. SSOCS has been conducted in school years 1999-2000, 2003-2004, and 2005-2006. 2007-2008 is available direct on the NCES site. Also see the NCES Bibliography for literature that has used this data.

  • Second International Self-Reported Delinquency Study, 2005-2007
    International collaborative study of delinquency and victimization of 12 to 15 year-old students in seventh, eighth, and ninth grade classrooms. School-based study that drew on random samples from either city level or national level. In general, the cross-national description of the prevalence and incidence of delinquent behavior allowed for the assessment of national crime rates by comparison with the crime rates of other countries. The study was conducted in 31 mostly European countries, the United States, Caribbean and South American countries. The primary research questions explored included: Is juvenile delinquency normal, ubiquitous, and transitional? Is there a pattern of similarity in the offending behavior of juveniles across countries or are there any important differences? Descriptive comparisons of crime rates will call for explanations, especially if differences are observed. What are the national socio-economic or cultural differences, or the characteristics of legal or criminal policies that can explain such differences?

  • Sourcebook of Criminal Justice Statistics
    Guide to tables and sources for criminal justice and crime in the United States.

  • State Court Processing Statistics (1990-2009)
    Undertaken to determine whether accurate and comprehensive pretrial data can be collected at the local level and subsequently aggregated at the state and federal levels. The data contained in this collection provide a picture of felony defendants' movements through the criminal courts. Offenses were recoded into 14 broad categories that conform to the Bureau of Justice Statistics' crime definitions. Other variables include sex, race, age, prior record, relationship to criminal justice system at the time of the offense, pretrial release, detention decisions, court appearances, pretrial rearrest, adjudication, and sentencing. The unit of analysis is the defendant. Formerly National Pretrial Reporting Program (1988-1993).

  • State Court Statistics (1985+)
    Provides comparable measures of state appellate and trial court caseloads by type of case for the 50 states, the District of Columbia, and Puerto Rico. Court caseloads are tabulated according to generic reporting categories developed by the Court Statistics Project (CSP) Committee of the Conference of State Court Administrators. These categories describe differences in the unit of count and the point of count when compiling each court's caseload. Major areas of investigation include (1) case filings in state appellate and trial courts, (2) case processing and dispositions in state appellate and trial courts, and (3) appellate opinions. The trial caseload consists of civil, domestic relations, criminal, juvenile, and traffic violation cases. The appellate caseload consists of appeal by right, appeal by permission, death penalty, and original proceeding/other appellate matter cases.

  • Survey of Campus Law Enforcement Agencies [United States] Series
    In 1995, to determine the nature of law enforcement services provided on campus, the Bureau of Justice Statistics surveyed 4-year institutions of higher education in the United States with 2,500 or more students. Describes nearly 600 of these campus law enforcement agencies in terms of their personnel, expenditures and pay, operations, equipment, computers and information systems, policies, and special programs. Based on the Law Enforcement Management and Administrative Statistics program, which collected similar data from a national sample of state and local law enforcement agencies. Follow-ups were conducted in 2004/2005 and 2011/2012.

  • Survey of Criminal Justice Experience (SCJE), 2013
    Household survey of the criminal justice experiences of United States adults ages 18-64. Measures capture supervision (e.g. probation, jail, and prison) and broader experiences such as arrests and convictions. Researchers are able to estimate 12-month and life-time prevalence rates of respondents' criminal justice experiences. Data were collected between May 8, 2013 and May 20, 2013. A random sample of 5,278 individuals aged 18-64 were selected from the KnowledgePanel and 3,260 participated in the survey. Along with the main survey variables, standard demographic variables, a series of data processing variables created by GfK, and a final sample weight are also included in the dataset. Demographic variables cover: age, race, sex, income, regions, education, marital status, employment status, and housing type.

  • Uniform Crime Reporting Program Data [United States] (1960+)
    Periodic nationwide assessments of reported crimes not available elsewhere in the criminal justice system. With the 1977 data, the title was expanded to Uniform Crime Reporting Program Data. Each year, participating law enforcement agencies contribute reports to the FBI either directly or through their state reporting programs. ICPSR archives the UCR data as 5 separate components: (1) summary data, (2) county-level data, (3) incident-level data (National Incident-Based Reporting System [NIBRS]), (4) hate crime data, and (5) various, mostly nonrecurring, data collections. Summary data are reported in four types of files: (a) Offenses Known and Clearances by Arrest, (b) Property Stolen and Recovered, (c) Supplementary Homicide Reports (SHR), and (d) Police Employee (LEOKA) Data (Law Enforcement Officers Killed or Assaulted). County-level data provide counts of arrests and offenses aggregated to the county level. County populations are also reported. In the late 1970s, new ways to look at crime were studied. The UCR program was subsequently expanded to capture incident-level data with the implementation of the National Incident-Based Reporting System. The NIBRS data focus on various aspects of a crime incident. Gathering of hate crime data by the UCR program was begun in 1990. Hate crimes are defined as crimes that manifest evidence of prejudice based on race, religion, sexual orientation, or ethnicity. In September 1994, disabilities, both physical and mental, were added to the list. The 5th component of ICPSR's UCR holdings is comprised of various collections, many of which are nonrecurring and prepared by individual researchers. These collections go beyond the scope of the standard UCR collections provided by the FBI, either by including data for a range of years or by focusing on other aspects of analysis. Also see Missing Data in the Uniform Crime Reports, 1977-2000. Select data is also contained in Data-Planet Statistical Datasets.

  • United States Sentencing Commission (USSC): Defendants Sentenced Under the Sentencing Reform Act, 1992-2009
    Examines how court decisions and sentencing policy changes have affected sentencing behavior in federal drug trafficking cases. Changes at the district level and in mandatory minimum sentencing were a particular focus. Data were obtained from the Defendants Sentenced Under the Sentencing Reform Act data from the United States Sentencing Commission from fiscal years 1992-2009. These data were then merged with federal district-level indicators for the 89 federal districts from the Federal Court Management Statistics website, and state level demographic data from the United States Census Bureau. Drug trafficking cases were identified by using the sentencing guideline offense, which resulted in a sample 0f N=376,637 cases.
