Family and Marriage:

A Cultural Construct and a Social Invention

More than one hundred years of cross-cultural research has revealed the varied forms humans have invented for “partnering”—living in households, raising children, establishing long-term relationships, transmitting valuables to offspring, and other social behaviors associated with “family.” Once again, the universality and evolutionary origins of the U.S. form of the human family is more fiction than fact, a projection of our cultural model of family and gender roles onto the past and onto the entire human species.

Families exist in all societies and they are part of what makes us human. However, societies around the world demonstrate tremendous variation in cultural understandings of family and marriage. Ideas about how people are related to each other, what kind of marriage would be ideal, when people should have children, who should care for children, and many other family related matters differ cross-culturally. While the function of families is to fulfill basic human needs such as providing for children, defining parental roles, regulating sexuality, and passing property and knowledge between generations, there are many variations or patterns of family life that can meet these needs. This chapter introduces some of the more common patterns of family life found around the world.
