Research
The Commission collects, analyzes, and disseminates a broad array of information on federal crime and sentencing practices. The Office of Research and Data collects data from documents submitted by the courts in each case in which a defendant is sentenced. From that data, the Commission prepares and disseminates public reports on a wide variety of sentencing issues. The Commission also uses this data in its consulting capacity to the courts, Congress, and the Executive Branch.

Research Reports
  • (March 2016) This report provides a broad overview of key findings from the United States Sentencing Commission’s study of recidivism of federal offenders. The Commission studied offenders who were either released from federal prison after serving a sentence of imprisonment or placed on a term of probation in 2005. In the future, the Commission will release additional publications discussing specific topics concerning recidivism of federal offenders.

  • (February 2016) This report examines sentence reductions for offenders who cooperate with the government in its efforts to investigate or prosecute others. Offenders can receive credit for their “substantial assistance” in at least two ways; at the time of sentencing (USSG §5K1.1 departure motions) and after sentencing (Federal Rule of Criminal Procedure 35(b) motions). In both instances, the government must make a motion for a lower sentence.

For context, it first briefly discusses the evolution of federal sentencing during the past four decades, including the landmark passage of the Sentencing Reform Act of 1984, as well as key Supreme Court decisions concerning the guidelines. It then describes the nature of federal sentences today and the process by which such sentences are imposed.

Data Files

The Commission's individual datafiles provide information on the sentences imposed in cases involving individuals. In these datafiles the individual is the unit of analysis. These datafiles do not contain information from the Commission's Organizational, Resentencing, or Appeals Databases.

The Commission's organizational datafiles provide information on the sentences imposed in cases involving organizational offenders (i.e., corporations, partnerships, and other entities having a legal existence separate from the individuals having an interest in them).

Commission datafiles that are used in various reports to Congress. These datafiles may contain information collected during a special coding project performed for a particular report and, therefore, will not be available in the Commission's fiscal year datafiles.
