Statement of Purpose:
These data are to be used for research and statistical purposes only. Use of the data for any purpose other than research or statistical purpose may constitute a violation of section 812(a) of the Omnibus Crime Control and Safe Streets Act of 1968, section 1407(d) of the Victims of Crime Act of 1984, or Part 22 of section 28 Code of Federal Regulations and may be subject to Federal prosecution and a fine of up to $10,000.

Please select a data file type:
  
  Standard Analysis Files:       Through its grantee the Urban Institute, BJS receives data extracts regularly from each agency's on-going case management system. The data extracts are used to create one or more "standard analysis files" (SAF). These SAF data files, designed by the Urban Institute, represent annual cohorts of suspects and defendants processed in the Federal criminal justice system—an incoming cohort, an outgoing cohort, and a cohort pending at the end of the fiscal year. (The source data extracts originally provided to BJS are stripped of information that could identify any individual and are archived at the National Archive of Criminal Justice Data—ICPSR Study Number 9296. through 1994. After 1994, these data are archived on the FJSRC website.) BJS uses the SAFs to prepare publications that describe various aspects of Federal criminal case processing.
  
  Linking data:       The new FJSRC linking system includes sets of paired-agency linked files created by improved methods of algorithmic matching. Each matched-agency pair file (or “dyad”) permits 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 paired-agency linked file relates the sequential record numbers (i.e. SEQ_NUM) included in the SAFs from one agency/stage to another. The system covers all data years from 1994-2008.
