Over the years, Congress has created or authorized the creation of numerous entities to carry out federal programs and further public purposes. Collectively, these entities receive trillions of dollars annually in funds appropriated by Congress. Given the wide variety of entity types, applicability of key broad-based requirements, and federal funding, this report: (1) identified and categorized federally created entities by type; (2) determined the extent to which the various entity types are generally subject to key broad-based statutory governance, accountability, and transparency requirements; and (3) determined the amount of appropriations Congress has made directly available to each of the individual entities in recent years (FY 2005 through 2008).
