How many people are there in your family? - There are # people in my family. Who are they? - They are my parents and me. We use the 'object pronoun me' because it answers the question 'they are who?' and 'I' is a subject pronoun and 'me' is the object pronoun, e.g., Subject Pronouns: - I am a member of my family. - You are a member of my family. - He/she/it is a member of my family. - We are members of my family. - You (plural) are members of my family. - They are members of my family. Object Pronouns: - There are my parents and me. You could say, "There are my parents and I", but that is old-fashioned and too formal. - There are six players on my team, including me. - He gave a gift to you and me [He gave a gift to you / He gave a gift to me.] - My brother works with you and me. [My brother works with you / My brother works with me.]

Most natural for me would be : "There are three of us - my parents and I".

"They are" and "there are" are both correct, but mean different things; the former naturally answers the second question, and the latter the first. Old-fashioned grammarians would insist on " ... and I" , but most people, at least colloquially, would say "... and me".
