Representative organization, leading the coordination work in the field of development of both global and national credit union movement is the World Council of Credit Unions (WOCCU) established in 1971 (headquartered in Madison, USA). Credit unions encourage savings of citizens, setting compensation payments (interest) on savings and provide from these savings loans to their members. When organizing the credit union it is important that people know each other and know the extent to which each of them is trustworthy. Is necessary that all shareholders of the credit union were members of a single community, would know each other well enough to enjoy mutual trust. Until the 70's there was a proliferation of the U.S. credit unions due to the increase of their number and the number of shareholders, although it must be acknowledged that there was also and a qualitative growth. Income derived from the provision of services to its members, does not become the profit of credit union and is distributed among its members in proportion to their savings. Credit unions historically formed as a special form of social support, initially taken upon themselves the social mission of protecting the interests of citizens in the field of financial services.
