Abstract“Group marriage”, as used in this paper, refers to a family structure in which three or more adult members (including at least one male and female) live together on a communal basis and share labor, goods, services, money, and the bearing and raising of children, and have sexual access to each other. Larry L. Constantine and Joan M. Constantine, who have done considerable research on group marriage, estimate that the number of such marriages in the United States probably does not exceed one thousand. In this paper the question is raised and on the basis of personal interviews examined whether or not group marriage is a viable alternative to the existing family structure. The author weighs the problems that he observed against the valuable experiences claimed and comes to the conclusion that apparently the former are too great at the present time for the people involved to overcome.
