Impact of Forensic Evidence on the Criminal Justice Process in Five Sites in the United States, 2003-2006 (ICPSR 29203)

Released/updated on: 2010-10-27
Geographic coverage: Indiana, United States, Los Angeles, California, Fort Wayne, South Bend, Evansville, Indianapolis
Time period: 2003-01-01--2006-01-01
The purpose of the study was to investigate the role and impact of forensic science evidence on the criminal justice process. The study utilized a prospective analysis of official record data that followed criminal cases in five jurisdictions (Los Angeles County, California; Indianapolis, Indiana; Evansville, Indiana; Fort Wayne, Indiana; and South Bend, Indiana) from the time of police incident report to final criminal disposition. The data were based on a random sample of the population of reported crime incidents between 2003 and 2006, stratified by crime type and jurisdiction. A total of 4,205 cases were sampled including 859 aggravated assaults, 1,263 burglaries, 400 homicides, 602 rapes, and 1,081 robberies. Descriptive and impact data were collected from three sources: police incident and investigation reports, crime lab reports, and prosecutor case files. The data contain a total of 175 variables including site, crime type, forensic variables, criminal offense variables, and crime dispositions variables.

National Crime Victimization Survey: School Crime Supplement, 2015 (ICPSR 36354)

Released/updated on: 2016-12-20
Geographic coverage: United States
The primary purpose of the School Crime Supplement (SCS) is to obtain additional information about school-related victimizations so that policymakers; academic researchers; practitioners at the federal, state, and local levels; and special interest groups who are concerned with crime in schools can make informed decisions concerning policies and programs. The SCS asks questions related to students' experiences with, and perceptions of crime and safety at school, including preventive measures employed by schools; students' participation in after school activities; students' perception of school rules and enforcement of these rules; the presence of weapons, drugs, alcohol, and gangs in school; student bullying; hate-related incidents; and attitudinal questions relating to the fear of victimization at school. These responses are linked to the National Crime Victimization Survey (NCVS) survey instrument responses for a more complete understanding of the individual student's circumstances.

National Crime Victimization Survey, [United States], 2016 (ICPSR 36828)

Released/updated on: 2020-07-27
Geographic coverage: United States

In October 2019, NACJD released a revised set of 2016 NCVS Public-Use Files. The National Crime Victimization Survey, [United States], 2016: Revised Version (ICPSR 37296) data collection contains the official 2016 NCVS data and replaces the previously published National Crime Victimization Survey, 2016 (ICPSR 36828) Public-Use Files. The initial files remain available for research purposes.

The National Crime Victimization Survey (NCVS) Series, previously called the National Crime Surveys (NCS), has been collecting data on personal and household victimization through an ongoing survey of a nationally-representative sample of residential addresses since 1973. The NCVS was designed with four primary objectives: (1) to develop detailed information about the victims and consequences of crime, (2) to estimate the number and types of crimes not reported to the police, (3) to provide uniform measures of selected types of crimes, and (4) to permit comparisons over time and types of areas. The survey categorizes crimes as "personal" or "property." Personal crimes include rape and sexual attack, robbery, aggravated and simple assault, and purse-snatching/pocket-picking, while property crimes include burglary, theft, motor vehicle theft, and vandalism. Each respondent is asked a series of screen questions designed to determine whether she or he was victimized during the six-month period preceding the first day of the month of the interview. A "household respondent" is also asked to report on crimes against the household as a whole (e.g., burglary, motor vehicle theft). The data include type of crime, month, time, and location of the crime, relationship between victim and offender, characteristics of the offender, self-protective actions taken by the victim during the incident and results of those actions, consequences of the victimization, type of property lost, whether the crime was reported to police and reasons for reporting or not reporting, and offender use of weapons, drugs, and alcohol. Basic demographic information such as age, race, gender, and income is also collected, to enable analysis of crime by various subpopulations. This version of the NCVS, referred to as the collection year, contains records from interviews conducted in the 12 months of the given year.

Basic demographic information such as age, race, gender, and income is also collected, to enable analysis of crime by various subpopulations. This version of the NCVS, referred to as the collection year, contains records from interviews conducted in the 12 months of the given year.

This dataset represents the revised version of the NCVS on a collection year basis for 2016. A collection year contains records from interviews conducted in the 12 months of the given year. Under the collection year format, victimizations are counted in the year the interview is conducted, regardless of the year when the crime incident occurred.

The 2016 National Crime Victimization Survey (NCVS) violent and property crime estimates were significantly higher than 2015, but it was not possible to determine the degree to which the change in rates resulted from the sample redesign rather than real changes in U.S. victimization levels. Therefore, the Bureau of Justice Statistics (BJS) examined the 2015 and 2016 victimization rates separately for new and continuing sample counties in the 2016 Criminal Victimization bulletin.

The BJS requested that the Census Bureau create a 2016 revised file with outgoing county interviews from July-December 2015, continuing county interviews from January-June 2016, and all interviews (continuing and new counties) from July-December 2016. In other words, the outgoing 2015 cases replaced the new 2016 cases in the first half of 2016. The files in this study serve as a separate research file to allow data users to make comparisons between 2015, 2016, and 2017 NCVS estimates using a nationally representative sample. It provides a sample that still represents the entire country but does not have the inflated crime rates seen in the new counties in 2016.

Project on Human Development in Chicago Neighborhoods (PHDCN): Deviance of Peers, Wave 1, 1994-1997 (ICPSR 13585)

Released/updated on: 2006-02-17
Geographic coverage: United States, Chicago, Illinois
Time period: 1994-01-01--1997-01-01
The Project on Human Development in Chicago Neighborhoods (PHDCN) was a large-scale, interdisciplinary study of how families, schools, and neighborhoods affect child and adolescent development. One component of the PHDCN was the Longitudinal Cohort Study, which was a series of coordinated longitudinal studies that followed over 6,000 randomly selected children, adolescents, and young adults, and their primary caregivers over time to examine the changing circumstances of their lives, as well as the personal characteristics, that might lead them toward or away from a variety of antisocial behaviors. Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. The Deviance of Peers was a self-report interview that obtained information about peer involvement in conventional and delinquent activities. Information about peer pressure to use drugs and/or alcohol was also collected.

The Deviance of Peers was a self-report interview that obtained information about peer involvement in conventional and delinquent activities. Compared to the Wave 1 version, a reduced set of items was included in Wave 2, but Wave 2 had additional questions regarding the age and gender of peers involved in particular behaviors. Information about peer pressure to use drugs and/or alcohol was also collected.

Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. One such measure was the Deviance of Peers instrument. It was a self-report interview that obtained information about peer involvement in conventional and delinquent activities. Compared to the Wave 1 version (PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): DEVIANCE OF PEERS, WAVE 1, 1994-1997 [ICPSR 13585]), a reduced set of items was included in Wave 3, but Wave 3 had additional questions regarding the age and gender of peers involved in particular behaviors. Information about peer pressure to use drugs and/or alcohol was also collected. It was administered to subjects in Cohorts 6, 9, and 12. The Wave 3 survey questions were identical to those asked in Wave 2 (PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): DEVIANCE OF PEERS, WAVE 2, 1997-2000 [ICPSR 13615]).
