On behalf of the Federal Judiciary, the Administrative Office of the U.S. Courts recently released the judicial caseload statistics for the fiscal year which ended September 30, 2012. The Federal Court Management Statistics system provides data for the 12 courts of appeals and the 94 district courts. Whether interviewing for a federal clerkship or researching the caseload of federal judges, these statistics detail the number of civil vs. criminal cases filed in each court, as well as the cases termintated on the merits vs. procedural terminations.
Archival statistics are available back to 1997 through the Federal Court Management Statistics system.
