The National Juvenile Court Data Archive houses over 15 million automated records of cases handled by courts with juvenile jurisdiction. Although some states' data contain traffic and dependency cases, the majority are delinquency and status offense records. The collection itself dates back to the 1920s when it was under the Children's Bureau, however in 1974 the Office of Juvenile Justice and Delinquency Prevention (OJJDP), within the U.S. Department of Justice assumed responsibility for the work of promoting access to automated juvenile court data sets for juvenile justice research and policymaking efforts. The Archive contains the most detailed information available on juveniles involved in the juvenile justice system and on the activities of U.S. juvenile courts. The Archive houses a sizable collection of automated juvenile court data files that not only support the national estimates but also support the study of a wide range of national and subnational juvenile justice issues. Designed to facilitate research on the juvenile justice system, the Archive's data files are available to policy-makers, researchers, students, and the public. The data have been used to explore a broad range of topics, from investigating the effectiveness of juvenile court programs and examining policy developments in individual jurisdictions, to monitoring the impact of legislative changes, and guiding juvenile justice system reform.

This data collection describes in quantitative terms the volume of juvenile cases disposed in 1994 by courts having jurisdiction over juvenile matters (delinquency, status offense, and dependency cases) in Missouri. Inaugurated in 1975 and mandated in 1980, the Missouri Division of Youth Services collects and disseminates delinquency statistics about each case disposed during the previous calendar year. The data include a record of each case processed formally with petition and informally without petition, and contain an individual record on each delinquency, status offense, dependency, and special proceeding case disposed.

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).

This data collection describes in quantitative terms the volume of juvenile cases disposed in 1994 by courts having jurisdiction over juvenile matters (delinquency, status offense, and dependency cases) in Arkansas. Inaugurated in 1983, the Arkansas Administrative Office of the Courts began to collect data from intake and probation departments on each case disposed during the previous calendar year. The data include a record of each case processed formally with petition and contain an individual record on each family in need of services, delinquency, or dependency/neglect case disposed.

Investigator(s): Office of Juvenile Justice and Delinquency Prevention The Census of Juveniles in Residential Placement (CJRP) was administered for the first time in 1997 by the United States Bureau of the Census for the Office of Juvenile Justice and Delinquency Prevention (OJJDP). The CJRP provides a detailed picture of juveniles in custody and asks juvenile residential custody facilities in the United States to describe each youth assigned a bed in the facility on the specified reference date. The CJRP reference date was generally the fourth Wednesday in October. Characteristics of the facility, treatment services, and facility population are also collected. Some state and regional agencies provide CJRP data for more than one facility under their jurisdiction. The CJRP facility inclusion criteria are: (1) residential facilities in operation on the census reference date, (2) public or private (or tribal since 1999) operation, and (3) intended for juvenile offenders (although some hold adults as well). Specifically excluded are: nonresidential facilities; detention centers operated as part of adult jails; facilities exclusively for drug or mental health treatment or for abused or neglected children; foster homes; and federal correctional facilities (e.g., Immigration and Naturalization Service, Bureau of Indian Affairs, United States Marshalls, or Bureau of Prisons). Inclusion criteria for individual-level data are: (1) youth under age 21, (2) assigned a bed in a residential facility at the end of the day on the census reference day, (3) charged with an offense or court-adjudicated for an offense, (4) and in residential placement because of that offense.Years Produced: Biennially since 1997, in odd-numbered years. (Note: The 2005 data collection was conducted in February 2006.) National Juvenile Corrections Data Summary The Office of Juvenile Justice and Delinquency Prevention sponsored three series of national juvenile corrections data collections:Census of Public and Private Juvenile Detention, Correctional, and Shelter Facilities Series,Census of Juveniles in Residential Placement (CJRP) Series, and theJuvenile Residential Facility Census (JRFC) Series.The CJRP was administered for the first time in 1997. The CJRP replaced the Census of Public and Private Juvenile Detention, Correctional, and Shelter Facilities (formerly called the Juvenile Detention and Correctional Facility Census series and also known as the Children in Custody (CIC) census), which had been conducted since the early 1970s. The CJRP differs fundamentally from CIC in that the CIC collected aggregate data on juveniles held in each facility (e.g., number of juveniles in the facility) and the CJRP collects an individual record on each juvenile held in the residential facility to provide a detailed picture of juveniles in custody. The companion data collection to CJRP, the JRFC, is designed to collect information about the facilities in which juvenile offenders are held.ICPSR merged data from the CJRP series with data from the JRFC series. These studies are included in the Matched Census of Juveniles in Residential Placement (CJRP)/Juvenile Residential Facility Census (JRFC) Series.

Connecticut's Juvenile Justice Policy and Oversight Committee (JJPOC) has developed this dataset and this dashboard to monitor and examine juvenile justice system involvement across the state for youth of different races, ethnicities, and genders. The following metrics were chosen to understand key points in the juvenile justice system: 1. Delinquent referrals 2. Non-judicial handling 3. Disposition of a first time felony 4. Detention Note: this dataset and the dashboard are being developed in phases, and as of 1/27/2023 they include data on Metric 1: Delinquent referrals and Metric 2: First Time Felony Dispositions. Additional metrics will be added over the course of 2023 and 2024.

This study assessed the effectiveness of the Youth Level of Service/Case Management Inventory (YLS/CMI or Y-LSI). The Y-LSI is an instrument for classifying juvenile offender risk of recidivism and for identifying areas of treatment need that, if addressed, will result in a reduced risk of recidivism. Three juvenile correction agencies in Ohio that used the Y-LSI for case classification were the settings for this study. Data in Part 1 were collected on 1,679 youths received in the three correctional settings between July 1, 1998, and June 30, 1999. Youths' files were reviewed to complete the data collection instruments. These files contained demographic and background information, Y-LSI assessments, and information relating to treatment and service referrals, completion of programming, and supervision outcome. One year after the initial Y-LSI assessments, reassessment data were collected on youths. Reassessments were completed on youth at the time of program completion or one year after the initial assessment. Supervision outcome data were collected two years after the initial data collection. Data in Part 2 were collected in 2001 through a survey of 196 agency staff members on their reactions to the use of the Y-LSI as a classification instrument.

This data collection contains information on juvenile delinquency and adult crime for three birth cohorts born in 1942, 1949, and 1955 in Racine, Wisconsin. These individual-level data are organized into three basic types: police contact data for the three cohorts, interview and contact data for the 1942 and 1949 cohorts, and contact data classified by age for all three cohorts. The police contact data include information on the type and frequency of police contacts by individual as well as the location, date, and number of the first contact. The interview datasets contain information on police contacts and a number of variables measured during personal interviews with the 1942 and 1949 cohorts. The interview variables include retrospective measures of the respondents' attitudes toward the police and a variety of other variables such as socioeconomic status and age at marriage. The age-by-age datasets provide juvenile court and police contact data classified by age.

This collection includes data collected from a subsample of participants interviewed near the end of the thirteenth follow-up of the Northwestern Juvenile Project (NJP). NJP is a longitudinal assessment of alcohol, drug, and mental health service needs and outcomes of juvenile detainees. The thirteenth follow-up occurred approximately 16 years after the baseline interview. The subsample of participants received two additional modules that were added to the interview. These interview modules, the Juvenile Justice Experiences module and the Weapons-Related Injury module, retrospectively assessed behaviors and experiences during adolescence. The original NJP sample included 1,829 randomly selected youth recruited at intake to the Cook County Juvenile Temporary Detention Center (CCJTDC) in Chicago, Illinois from 1995 to 1998. The sample was stratified by gender, race/ethnicity, age, and legal status (for a total of 13 strata) to obtain enough participants to examine key subgroups. Both additional modules were administered at follow-up thirteen to a subsample 389 participants. The Juvenile Justice Experiences module assessed experiences with corrections in the juvenile justice system. Items were drawn from the Survey of Youth in Residential Placement (SYRP) which ask a series of questions covering an individual's emotion and mental states among youth who are in custody. NJP utilized a modified SYRP to assess juvenile justice experiences retrospectively among the sample. The Weapons-Related Injury module was created for the NJP, and assesses gunshot-related and stabbing-related victimization during adolescence.

This data collection, the first survey of youths confined to long-term, state-operated institutions, was undertaken to complement existing Children in Custody censuses. It also serves as a companion to the Surveys of State Prisons, allowing comparisons between adult and juvenile populations. The survey provides detailed information on the characteristics of youths held primarily in secure settings within the juvenile justice system. The data contain information on criminal histories, family situations, drug and alcohol use, and peer group activities. For youths committed for violent acts, data are available on the victims of their crimes and on weapon use.
