The family is a foundational social institution that impacts individual lives and reflects broader societal structures. This section categorizes family types into nuclear and extended, addressing their distinct characteristics and changes over time. It notes that family structures can be male or female-headed and their lineage may follow matrilineal or patrilineal lines. The text emphasizes that the family is interlinked with economic, political, cultural, and educational spheres, highlighting how larger societal shifts can lead to changes within family structures. For example, migration patterns or changes in employment types can result in more female-headed households or increased grandparental caregiving roles. Further, the dynamic nature of family norms is illustrated, showing how contemporary influences challenge traditional values, and how resistance to change is often strong.
