This document discusses different types of family structures and changes that have occurred. It describes the nuclear family as consisting of parents and children, and the extended family as including other relatives like grandparents, aunts, uncles and cousins living together. Another type is the joint family where parents, children and grandchildren all live in one house. It notes an increase in single parents raising families alone due to factors like death of a spouse or early pregnancy. Modern changes include more mothers working outside the home and children spending more time online rather than socializing in person. Authority in families has shifted away from strict father dominance to children having more independence and voice.
