"The Executive Office for United States Attorneys (EOUSA) provides general executive assistance and supervision to the Offices of the United States Attorneys and coordinates the relationship of the United States Attorneys' offices with other organizational units of the Department of Justice and other Federal agencies. One of EOUSA's responsibilities on behalf of the United States Attorneys is the publication of the United States Attorneys' Statistical Report. As an integral part of their prosecution and litigation efforts, the United States Attorneys rely on a centralized case management system to track information on the criminal and civil matters, cases, and appeals that they handle. The charts and tables presented in this report reflect a statistical summary of the matters and cases handled by the United States Attorneys."
