A nonprofit organization is often dedicated to furthering a particular social cause or advocating for a particular point of view. In economic terms, a nonprofit organization uses its surplus revenues to further achieve its purpose or mission, rather than distributing its surplus income to the organization's shareholders (or equivalents) as profit or dividends. Overall, they tend to be either member-serving or community-serving. Member-serving organizations include mutual societies, cooperatives, trade unions, credit unions, industry associations, sports clubs, retired serviceman's clubs and advocacy groups or peak bodies – organizations that benefit a particular group of people, i.e. the members of the organization.
