Many cooperatives, both large and small, have formed associations with each other to promote the development of new cooperatives. Some prominent associations have been instrumental in the birth of new enterprises including: the National Cooperative Business Association, the Cooperative Housing Federation of Canada, the Credit Union National Association, and the Canadian Cooperative Association. The North American Students of Cooperation, or NASCO, is the counterpart organization on the student level.
