National Archive of Criminal Justice Data

This dataset is maintained and distributed by the National Archive of Criminal Justice Data (NACJD), the criminal justice archive within ICPSR. NACJD is primarily sponsored by three agencies within the U.S. Department of Justice: the Bureau of Justice Statistics, the National Institute of Justice, and the Office of Juvenile Justice and Delinquency Prevention.

Augmented Federal Probation, Sentencing, and Supervision Information System, 1985 (ICPSR 9664)

Principal Investigator(s):


The United States Sentencing Commission, established by the 98th Congress, is an independent agency in the judicial branch of government. The Commission recommends guidelines prescribing the appropriate form and severity of punishment for offenders convicted of federal crimes. These data were collected to determine whether sentencing disparities existed and whether the guidelines were adequate. Basic information in the collection includes a description of the offense, characterization of the defendant's background and criminal record, method of disposition of the case, and sentence imposed. Felony and misdemeanor cases are included while petty offense cases are excluded. Three types of additional information were used to augment the existing data: (1) more detailed offense and offender characteristics identified by the United States Sentencing Commission but coded by federal probation officers, (2) actual time served in prison from the SENTRY data file of the United States Bureau of Prisons, and (3) information necessary to estimate prospective release dates from the hearing files of the United States Parole Commission. The unit of analysis is the defendant.
