In 1908. the spread of credit unions has reached the United States. In 1935 President Roosevelt signed the state Charter on credit unions, which became a law. Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. Principles of cooperative democracy and interaction were adequate to the purposes for which people joined credit unions. All the members of the credit union, regardless of gender, ethnicity, religious and political beliefs, as well as the size of the monetary share have equal rights. Since the early 80's started the process of consolidation of credit unions, leading to a decrease in their number with a simultaneous increase in the total number of members. Over 30% of the assets of credit unions are investments in government securities, certificates of deposit of banks and savings loan associations, as well as in the parent credit unions, and other risk-free investments. 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 cooperatives and credit unions exist in many different forms. The main differences relate to the nature of the membership and the opening of a credit institution. Unlike banks credit unions limit their activities to a closed circle of people.
