Corporate credit unions are united on a cooperative basis in the Central Credit Union (US Central Credit Union). 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. Credit unions appeared in England in the 19th century. In 1844 a group of workers from Rochdale established the first cooperative. The relationship between credit unions and shareholders arise from the membership and are not customer relationship. On the consumer credit market in the U.S. credit unions are on the third place after the commercial banks and finance companies and are ahead of savings institutions, not taking into account the loans on real estate.
