Answer :

Final answer:

The stages of a family are differentiated based on the age of children and understanding these stages helps analyze family dynamics and cater to their needs.


Explanation:

The criterion used to differentiate the stages of family is based on the age of children. Family life cycle stages can be categorized by the age of the children within the family unit. For example, one common categorization includes families with children under 14, families with children over 14 but under 36, and old families.

Each stage presents unique challenges and dynamics. The problems and challenges a family faces in each stage vary, such as child-rearing concerns for families with young children versus relationship dynamics for families with teenagers.

Understanding these stages helps researchers and sociologists analyze family dynamics over time and assists marketers in providing appropriate goods and services for families at different life cycle stages.
