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.

Commission Datafiles
 
Individual Offenders

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.

Corporate Offenders

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).

Special Projects

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.
