In the U.S., credit unions have a clear organizational structure. All credit unions belong to one or the other parent credit union (there are 35 of them in the U.S.). When organizing the credit union it is important that people know each other and know the extent to which each of them is trustworthy. 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. Until the mid-XX century, credit unions in the United States had little assets that did not exceed, as a rule, 100 thousand dollars The value of credit unions is not limited to the role of the economic agent - they are an important element of the social structure and a factor of social stability and progress. 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.
