Which group consists of parents and children living together?

The term 'family' is defined as a group of individuals related by blood, marriage, or adoption, and often encompasses parents and their children living together in a single unit. This arrangement typically involves a shared residence and familial relationships, providing emotional and social support. While other groups such as a 'household' can also involve parents and children living together, the term 'family' captures the deeper relational connections and responsibilities inherent in the parent-child dynamic. It's focused on the personal bonds and the structure of relationships, making 'family' the most appropriate term for a group of parents and their children living under one roof.
