False. A number of families which are not nuclear exist in the United States today. A nuclear family is a family group consisting of a pair of adults and children. However there are families which exists with only one parent due to a widower or because there has been a divorce. Their also exists families with parents of the same gender and since the nuclear family was based on the typical Christian family a lot of the time in the United States, there are also families where the parents do not have the same religion which is atypical.
