This research project used longitudinal data on 524 serious male juvenile offenders released from California Youth Authority (CYA) institutions from 1965-1984 to examine the relationship between changes in local life circumstances (marriage, employment, drug use, alcohol use, street time) and criminal offending. In particular, the project extended previous research on criminal careers by developing and applying an empirical model that accounted for the joint distribution of violent and nonviolent criminal offending by parolees in their late teens to mid-20s, during a newly recognized developmental period of the life course termed "emerging adulthood." The individuals were released from the CYA at various ages from the late teens to early 20s, but were all followed for a seven-year post-parole period. For each individual, the researchers obtained information on counts of criminal arrests as well as information on exposure time. Violent arrests included murder, rape, aggravated assault, robbery, and other person offenses such as extortion and kidnapping. Nonviolent arrests included burglary, receiving stolen property, grand theft, forgery, and grand theft auto. Within each year, individuals were coded as "free" for the number of months that they were not serving time in jail, prison, or CYA detention. Involvement of the following life circumstances was recorded: (1) alcohol use, (2) heroin use, (3) full-time employment, and (4) marriage. A "month-score" indicating how many months the parolee was employed full-time during the course of each of the seven years of observation was also recorded. Offenders were assumed to have maintained the same status unless a change was noted in the California Department of Corrections files. In addition, the researchers developed an index to gauge an offender's stake in conformity by combining the life circumstances of marriage and full-time employment. Variables in the data include year of follow-up, race, age during that year of follow-up, number of months not serving time, stake in conformity index score, and number of arrests for violent offenses, nonviolent offenses, and total offenses. Dummy variables are provided on alcohol use, heroin use, use of mind-altering drugs, use of uppers/downers, dependence on alcohol or heroin, marital status, common-law marriage, and employment.

Patterns of adult criminal behavior are examined in this data collection. Data covering the adult years of peak criminal activity (from approximately 18 to 26 years of age) were obtained from samples of delinquent youths who had been incarcerated in three California Youth Authority institutions during the 1960s: Preston, Fricot, and the Northern California Youth Center. Data were obtained from three sources: official arrest records of the California Bureau of Criminal Investigation and Identification (CII), supplementary data from the Federal Bureau of Investigation, and the California Bureau of Vital Statistics. Follow-up data were collected between 1978 and 1981. There are two files per sample site. The first is a background data file containing information obtained while the subjects were housed in Youth Authority institutions, and the second is a follow-up history offense file containing data from arrest records. Each individual is identified by a unique ID number, which is the same in the background and offense history files.

This study examines the criminal activities of a group of young offenders after their release from prison to parole supervision. Previous studies have examined recidivism using arrests as the principal measure, whereas this study examines a variety of factors, including length of incarceration, age, sex, race, prior arrest record, prosecutions, length of time between parole and rearrest, parolees not prosecuted for new offenses but having their parole revoked, rearrests in states other than the paroling states, and the nature and location of rearrest charges. Parolees in the 22 states covered in this study account for 50 percent of all state prisoners paroled in the United States in 1978.

These data were gathered to investigate the usefulness of statistical methods, particularly multiple-regression analysis, in predicting repeat criminal activity subsequent to an individual's release from prison. The data collection consists of follow-up information, collected in 1988, on a sample of males released from California prisons. The follow-up study identified criminal activity subsequent to individuals' release from prison through 1988. Predictor variables include age, prior periods of arrest, history of drug use, seriousness of original offense, and number of arrests for nuisance, person, property, and fraud offenses.

The NLSY97 standalone data files are intended to be used by crime researchers for analyses without requiring supplementation from the main NLSY97 data set. The data contain age-based calendar year variables on arrests and incarcerations, self-reported criminal activity, substance use, demographic variables and relevant variables from other domains which are created using the NLSY97 data. The main NLSY97 data are available for public use and can be accessed online at the NLS Investigator Web site and at the NACJD Web site (as ICPSR 3959). Questionnaires, user guides and other documentation are available at the same links. The National Longitudinal Survey of Youth 1997 (NLSY97) was designed by the United States Department of Labor, comprising the National Longitudinal Survey (NLS) Series. Created to be representative of United States residents in 1997 who were born between the years of 1980 and 1984, the NLSY97 documents the transition from school to work experienced by today's youths through data collection from 1997. The majority of the oldest cohort members (age 16 as of December 31, 1996) were still in school during the first survey round and the youngest respondents (age 12) had not yet entered the labor market.

The purpose of the study was to investigate the criminal career patterns of violent offenders. These data are intended to facilitate the development of models to predict recidivism and violence, and to construct parole supervision programs. Original data were collected on young male offenders in 1964 and 1965 as they entered the California Youth Authority (CYA). At this time, data were collected on criminal history, including current offenses, drug and alcohol use, psychological and personality variables, and sentencing, and demographics such as age, education, work experience, and family structure. The data collection also contains results from a number of standardized psychological instruments: California Psychological Inventory, Minnesota Multiphasic Personality Inventory, California Achievement Test Battery, General Aptitude Test Battery, Army General Classification Test, and the Revised Beta Test. After release from the CYA and over the following 20 years, subsequent arrest information was collected on the offenders, including the nature of the offense, disposition, and arrest and parole dates.

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.
