A membership organization is a group or association that consists of individuals who have joined together for a common purpose, goal or interest. These organizations typically require some form of payment (known as dues) from their members in exchange for access to resources and benefits such as networking opportunities, educational programs, publications, conferences, political representation, and other services tailored to the group's specific interests. Membership organizations can be professional associations, trade unions, advocacy groups or clubs among others. The main objective of these organizations is to provide value to their members by promoting their common interest through collective action and engagement in activities that benefit them as a whole.
