How a nuclear family is formed?

A nuclear family is formed when two parents, typically a mother and father, come together, often through marriage or a committed relationship, to raise their biological or adopted children. This family structure is characterized by its focus on the immediate family unit, which usually consists of one or two parents and their children, living together in a single household. The nuclear family serves as a primary social unit, providing emotional support, economic stability, and socialization for its members.
