As of 2014, there are 94 federal judicial districts in the United States. There is at least one district in each state, the District of Columbia and Puerto Rico. There are also federal judicial districts in three U.S. territories: Guam, the Virgin Islands and the Northern Mariana Islands.
The district courts are trial courts of the federal court system. Under the U.S. Constitution, these courts have jurisdiction to hear both civil and criminal cases. Each district also has authority over a bankruptcy court. Each court has judges, court reporters, clerks and other personnel who are employed by the judicial branch of the government. All districts have a federal public defender to represent those who are charged with a federal crime and cannot pay for a lawyer.
