The new FJSRC linking system, implemented with the 2008 FJSRC data, includes sets of agency dyad linked files created by improved methods of algorithmic matching. There are both inter-agency linked files and intra-agency dyad linked files.

The inter-agency matched pair files (or "dyads") permit the linking of records from two different source agencies for adjacent stages of federal case processing by providing a crosswalk of the agency-specific key ID variables for the two agency data files in the pair. These agency ID variables (sequential ID numbers) may be used to link records from one agency's standard analysis file (SAF) to the next. The system enables users to track individual defendant-cases through stages of the federal criminal justice system (from arrest to prosecution, adjudication, sentencing, and corrections) sequentially, one agency dyad pair at a time. Each inter-agency paired linked file relates the sequential record numbers (i.e. SEQ_NUM) included in the SAFs from one agency/stage to another.

The intra-agency matched pair files (also dyads) permit the same type of linking as described above except that the linkages are within the same federal agency. The linkages are to different stages of case processing withing a particular agency.

The system covers all data years from 1994-2014. These data are part of a series designed by the Urban Institute (Washington, D.C.) and the Bureau of Justice Statistics. Data and documentation were prepared by the Urban Institute through 2012. Data from 2013 and on were prepared by Abt Associates.

2018-04-17 The data files were updated to include information for 2014.

2017-06-16 An incompatibility in the sequence numbers between the archived USSC data and the AOSC dyads involving an extra non-identifying zero in the USSC dyad sequence number was found. Dataset 4, AO Cases OUT SAF and USSC OUT SAF, has been corrected and updated as a result.

2016-09-19 The JWSCORE and MAGFLAG variables, present in previous dyad linking files, have been removed to ease use of the linking files. In addition, the data files were updated to include information for 2013.

2015-02-05 The data files were updated to include information from 2012.

2014-06-16 The data files were updated to include information for 2011.

2013-05-17 The collection was updated to replace datasets 1-9 and add dataset 10. All datasets contain information through 2010.

2013-05-17 The codebook was updated to reflect new data files.

2011-11-11 The study was updated to replace dataset 1 and add datasets 6, 7, 8 and 9.

2011-08-08 Data parts 2, 3 and 4 were updated to include new values for the variable JWSCORE.

2011-07-22 2011-07-22 The data files were updated to include information for 2009.

2011-06-14 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:

  • Created variable labels and/or value labels.


  • The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.

  • One or more files in this data collection have special restrictions. Restricted data files are not available for direct download from the website; click on the Restricted Data button to learn more.

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.
