Pediatricians provide care for children who live in a variety of family situations. Children may live with 2 working parents, unmarried parents, grandparents, or other nonparental caregiver; or they may live in single-parent families where the mother or father may be divorced or never married; or they may live with lesbian, gay, bisexual, or transgendered (LGBT) parents; in foster homes; or in blended families. The traditional nuclear family, consisting of a mother and a father who are married and living with their biological children, is becoming rare; in fact, only 25% of households fit this description. Although it was the norm decades ago, today only one-half of American households include a married couple, and only one-half of those have children. Only 14% of children are raised in a 2-parent home with a working father and a mother who stays home full time. Given the diversity of family forms, it is important to identify the ideas central to the definition of family.
The notion of family is universal in all cultures and societies, but the definition is changing and is often vague. At a broad, conceptual level, the family is a system of social relationships that are shaped by expectations and values and that are based on distinctions of age and gender. Each member occupies a particular position or status that governs behavior toward other family members. On a more practical level, the US Bureau of the Census defines a family as 2 or more persons who live together and are related by blood, marriage, or adoption.
CHARACTERISTICS OF FAMILIES
Given the difficulty in defining family, it may be useful to conceptualize the characteristics and functions of family units. First, many families share biology, including temperament, personality, talent, and disease vulnerability. Second, families typically have a power hierarchy that is determined in part by age, generation, culture, personality characteristics, and gender. Third, families tend to have their own “culture,” which includes a family-specific set of values, goals, and expectations. Although they are unique to each family, these “microcultures” reflect the larger societal and ethnic cultures. Fourth, every family has an “invisible boundary” that defines who is a member and who is not.
Another set of family characteristics is developmental and arises from a family’s common history and future. Family history may be completely unknown or extend back for generations, reflecting both ethnic and religious beliefs and the dramatic life-altering events that have affected the family. A family’s future course usually follows a pattern of successive developmental phases that depend in part on both biology and social norms. The phase of expansion includes the initial parental union and continues until the youngest child becomes an adult. This period spans fertility and the physical and emotional maturation of children. The phase of dispersion occurs when the first child achieves adulthood and leaves home. The phase of independence begins when all ...
