都可数，family是集体名词，只是根据句意取单复数形式。eg:I have a big family.这是是家庭的意思，作可数单数。My family are all music lovers.这里家人就是作可数复数
For example:
My family likes eating ice cream. (Singular because everyone in the family likes eating ice cream).
My family (members) like different types of ice cream. (Plural because they like different types of ice cream. Also, because I can add #34members#34 and have the sentence make sense, I can use #34family#34 as a plural noun).
Her family (members) are all doctors (plural).
Her family is one of the oldest on the island (can#39t add #34members#34 so it#39s singular).
When talking about two or more different families, #34family#34 is a countable noun.
We meet up with two other families each summer.
You can also say #34They are (part of) my family.#34 This would be used to describe two individuals rather than the family.
Jim: Do you know Sarah and Steve?
Sam: Yes, they are my family.
#34This is my family,#34 describes the family as a unit so it is singular.
