Nuclear family

A nuclear family can consist of a man and a woman (married or living together) with or without (own) children, or: a man or a woman with children. This concept deals primarily with the so-called biological unit. Often it happens that in the household of such a nuclear family live other people: family and/or non-family members.

Note: Every person in a household with more than one nuclear family is by definition member of only one household. Note
