What makes a complex society complex?

A complex society is characterized by a high degree of social stratification, diverse cultural practices, and intricate economic systems. It typically features specialized roles and occupations, advanced technologies, and a centralized political structure that governs interactions among its members. The interdependence of various social institutions, such as family, education, and governance, further contributes to its complexity. Additionally, complex societies often engage in extensive trade and communication, both internally and with other cultures, enhancing their overall intricacy.
