Activity of the credit union consists of organizing mutual financial assistance by meeting the needs of its members in the services of saving and obtaining loans. Principles of cooperative democracy and interaction were adequate to the purposes for which people joined credit unions. Typically new members of the credit union become citizens having suretyship or recommendations from their friends - members of the credit union. 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. Credit unions appeared in England in the 19th century. In 1844 a group of workers from Rochdale established the first cooperative. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.). Unlike banks, in order to use the services of a credit union, you have to become its member, having written an application and having paid thus shares and membership fee. A credit union on its own initiative order is created by citizens (individuals) to solve their financial problems that they could not solve in other financial institutions. Today, the World Council of Credit Unions is represented as members four regional confederations and twelve national associations.
