What are the characteristics of nuclear family?
Two adults and their children.
The traditional family structure is called a nuclear family. A nuclear family consists of a married couple and any number of kids, but at least one. Every nuclear family has these attributes. After these characteristics, people have different opinions on how the nuclear family structure is modelled. It is all just opinions, but some people think that the couple has to be biological parents of the child(ren).
A nuclear family is husband, wife and their non-adult children. An extended family is a nuclear family with their more distant relatives, such as grandparents, aunts and uncles, cousins, etc. Sometimes extended families live together or near each other. Sometimes nuclear families are widely separated from their relatives. Then the extended family still exists but does not interact as closely.
They vary in size.. The nuclear family consits of both parents and children while the extended family consists of various members of the family E.g. grandmother, grandfather, uncle, aunt etc.. A nuclear family consists of the parents and their children. The extended family consists of all the aunts, uncles, cousins, grandparents, grandchildren, in-laws, etc.
To what extent is the family life still important despite the decline of nuclear family in modern instrialised society?
The nuclear family is typically a modern family. The post modern family could be a nuclear family that broke apart due to a divorcy and now transformed into a patchwork family. Could also be one where there is only two parents and no children. Something like that. I hope that helps. Here is more about that topic: http://archive.unu.edu/unupress/unupbooks/uu13se/uu13se03.htm
