The U.S. Federal Government, a state-owned entity established in 1789, is responsible for the administration of the United States. Employing approximately 10,360 individuals (this number likely refers to a specific subset of federal employees and not the entire federal workforce), its headquarters are located in the United States. Its structure is defined by a tripartite system of government, dividing power among the legislative, executive, and judicial branches as outlined in the U.S. Constitution.
