Please explain how skin color is relevant in the interview context and why it was specifically mentioned in the original post. Please explain how skin color is different from race for the purpose of this discussion.
The specific term was 'demographic', your quote did not include the word race.
EDIT: Upon re-reading... are you really asking me to explain why skin color is part of a demographic? I guess I glossed over that because it doesn't make sense unless youwant to imply that mentioning 'white' in the context of other demographic variables like age and location is racist...in which case, census forms are racist.
