What did Murdock's survey suggest about the nuclear family?

Murdock's survey suggests that the nuclear family is a universal family structure because he found evidence that it exists in every culture he studied. According to his research, the nuclear family, which consists of two parents and their children, is a fundamental social unit that transcends cultural differences. This notion is significant because it implies that despite varying cultural practices and family forms, the nuclear family plays a crucial role in the organization of society across different regions. Murdock's conclusions highlight the importance of the nuclear family as a consistent aspect of human social life, providing a framework that supports various social functions, such as reproduction, socialization of children, and economic cooperation.
