Monogamy Family

According to the Ethnographic Atlas, of 1,231 societies from around the world noted, 186 were monogamous; 453 had occasional polygyny; 588 had more frequent polygyny; and 4 had polyandry. However, this does not take into account the relative population of each of the societies studied, and the actual practice of polygamy in a tolerant society may actually be low, with the majority of aspirant polygamists practicing monogamous marriage.

Many societies that we consider monogamous in fact allow easy divorce. In many western countries divorce rates approach 50%. Those who remarry do so on average 3 times.[citation needed] Divorce and remarriage can thus result in "serial monogamy", i.e. multiple marriages but only one legal spouse at a time. This can be interpreted as a form of plural mating, as are those societies dominated by female-headed families in the Caribbean, Mauritius and Brazil where there is frequent rotation of unmarried partners. In all, these account for 16 to 24% of the "monogamous" category.
