FAQ
Frequently Asked Questions
Not exactly. 'Immediate family' can include relatives like grandparents who don't live with you, while 'nuclear family' specifically refers to co-resident parents and children.
From the Latin 'nucleus' meaning kernel or core, emphasizing it as the basic, central family unit from which larger family networks extend.
While still common, its prevalence has decreased in many societies due to factors like rising single-parent households, cohabitation without marriage, and multigenerational living.
Some sociologists include single-parent with children as a variant, while others restrict it to two-parent households. The term is sometimes stretched in modern usage.
