Organizations in this industry promote the business, professional, and political interests of their members. Major US organizations include the AARP, the American Automobile Association (AAA), the American Bar Association, the National Association of Realtors, and the National Football League (NFL), as well as the DNC (Democratic National Committee) and RNC (Republican National Committee). International organizations include the International Law Association (based in the UK) and the International Chamber of Commerce (France).
Demand is driven by business and political activity. The profitability of individual organizations depends on membership dues and effective marketing. Large organizations have advantages in diverse membership. Small organizations can compete effectively by serving niche industries and local markets.
Major sources of revenue include membership dues (30 to 50 percent of revenues), convention and seminar fees (up to 25 percent), and publications (less than 10 percent). Revenues may also come from testing and examination services. An organization may offer members certification to ensure proper qualifications or to designate level of expertise. Other non-dues related revenues may include sales of services and merchandise. (For example, AAA offers roadside assistance and maps.)
