The Traditional Set-up
What is a Nuclear Family
A nuclear family is a couple and their dependent children, regarded as a basic social unit. Specifically this would include a mother and a father who are married (with no previous maritial ties) and have children (generaly two or three of their own biologically) and in some cases a pet like a cat or a dog. The nuclear family was the norm up untill the latter part of the 20th century. With rising divorce rates and other social changes today, the nuclear family is in decline.
