Offender Based Transaction Statistics (OBTS), 1983: California, Minnesota, Nebraska, New York, Ohio, Pennsylvania, Utah, Virgin Islands, and Virginia (ICPSR 8449)
Alternate Title: OBTS 1983
Principal Investigator(s): United States Department of Justice. Bureau of Justice Statistics
Offender Based Transaction Statistics (OBTS) studies are designed to collect information by 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. Information is provided on arrest, police action, prosecutor action, level of charges, charges filed by the prosecutor, type of counsel, pretrial status, type of trial, sentence type, and sentence length. This allows researchers to examine how the criminal justice system processes offenders, to measure the changing volume of offenders moving through the different segments of the criminal justice system, to calculate processing time intervals between major decision-making events, and to assess the changing structure of the offender population.

Scope of Study
Date of Collection:
Universe: Persons in the United States who have achieved adult status (as specified by individual state laws) and who have been processed for felonies by the police, prosecutors, or courts, whether or not there is a final determination of guilt.
Data Types: event/transaction data, and survey data
Data Collection Notes:
For reasons of confidentiality, the "day" variables in the dates have been blanked in the public release version of the data. Consequently, additional variables have been created to provide the elapsed time between the day of arrest and the days of the police disposition, the prosecutor/grand jury disposition, the final court disposition, and the sentencing date.
computerized court records
Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Performed recodes and/or calculated derived variables.
- Checked for undocumented or out-of-range codes.
Original ICPSR Release: 1986-03-28
- 2005-08-08 The data were reprocessed using resupplied data. Old ICPSR administrative variables were removed. The variables "Date of Arrest: Day," "Date of Police Disp: Day," "Date Prosec Dispos: Day," "Date Final Court Disp: Day," and "Sentencing Date: Day," previously removed from the data, have been included in the data files. A public version of the data has been created in which the Day variables are blanked and a restricted version of the data has been created in which the Day variables have not been blanked. Also, Parts 2 and 3, which were old frequency files, have been removed. The codebook and all the SAS, SPSS, and Stata collection files have been updated to reflect the changes.
- 2004-02-24 The data were converted from card image to logical record length format. The documentation and SPSS data definition statements were updated to reflect the new format, and SAS data definition statements were prepared.
