Data are received each year from participating agencies (U.S. Marshals Service, Drug Enforcement Administration, Executive Office for U.S. Attorneys, Administrative Office of the U.S. Courts, U.S. Sentencing Commission, and Federal Bureau of Prisons) and standardized by BJS using statistical programs to create a common unit of analysis, an equivalent period for reporting of events (fiscal year), and a common offense classification scheme. The unit of analysis is the defendant-case or an individual defendant appearing in a case. In addition, the process of creating these standardized data files includes removing any information that could be used to identify any individual and processing and documenting data so that it is suitable for analysis.
