Here's why:
* Collective nouns refer to a group of people or things considered as a single unit.
* While a family consists of individual members, we often think of it as a whole entity.
For example:
* "My family is going on vacation." (The entire group is considered one unit)
* "The family gathered for dinner." (Again, emphasizing the group as a whole)
