The U.S. Chamber of Commerce is the world’s largest not-for-profit federation of businesses, representing more than 3 million businesses and organizations in the United States. As of 2003, the chamber was comprised of 3000 state and local chambers and 830 business associations. There were also 92 U.S. Chambers of Commerce abroad. Businesses that make up the chamber range from Fortune 500 companies to home-based operations consisting of one or two people. Approximately 96 percent of the chamber membership consists of businesses with fewer than 100 employees. The chamber states that its mission is to “advance human progress through an economic, political, and social system based on individual freedom, incentive, initiative, opportunity, and responsibility.” The chamber has historically been an influential lobbyist for legislation that favors the free enterprise system. It looks to its membership to help define policy on national issues critical to business. Once a policy is developed, the chamber informs Congress and the administration of the business community’s recommendations on legislative issues and government policies.
