In recent decades, many credit unions began to resort to such form of service as National Credit Union Insurance Fund was created by Congress in 1970 to insure deposits of credit union members in the amount of 100 thousand dollars. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others. U.S. credit unions have another significant difference from the credit cooperatives of farmers: the first have major proportion of short-term loans, the second - long and mostly in real estate. Unlike banks credit unions limit their activities to a closed circle of people.
