Is a nuclear family an out-dated institution?

Introduction:
A “nuclear family” is a family that consists of a working father, a mother who was a housewife, and one or more children (Brym, 2014, pp. 22).

For the past century, the dominant family type was composed of a married couple as its core, and biological children, forming the ideal- typical nuclear family unit.

In an experiment on youth opinions about family dynamics, youth are conflicted about whether their parents should stay together. A slight majority wished that their parents, who have split up, stayed together. However, close to half concluded that parental separation was better than living
