Final answer:
A family made up of a mother, father, and stepchildren is called a blended family, which merges two previously separate families into one new unit.
Step-by-step explanation:
A family consisting of a mother, father, and stepchildren is known as a blended family. Blended families are formed when one or both parents remarry and bring their own children into the new family unit. It is a common family structure in societies with a high rate of divorce or widowhood, such as the United States. According to Pew Research, around 16 percent of American children live in blended families.Blended families form when divorced or widowed individuals with children remarry, merging two separate families into one. In these families, there can be step-siblings and half-siblings living together under one roof.
The concept of family can vary, but in Western societies, it traditionally means a nuclear family of parents and their immediate offspring. However, extended families may also live together, including a broader circle of relatives such as grandparents, aunts, uncles, and cousins. These definitions reflect the diversity and complexity of family structures in today's society.
