Of the 1,231 societies listed in the 1980 Ethnographic Atlas, 186 were found to be monogamous, 453 had occasional polygyny, 588 had more frequent polygyny, and four had polyandry.Ethnographic Atlas Codebook derived from George P. Murdock's Ethnographic Atlas recording the marital composition of 1,231 societies from 1960 to 1980. Polyandry is less rare than this figure suggests, as it considered only those examples found in the Himalayan mountain region (eight societies). More recent studies have found at least four other societies practicing polyandry.
