Question

Do people know the definitive difference between race and ethnicity and also to culture?

Answer 1

Most people do not know the difference.

Race is a biological classification. I think of it as something that can only be seen on the outside, or through physical characteristics. Ethnicity is more about social grouping. It refers to the culture that one comes from, but the term has a more specific context. For example, "hispanic" is an ethnicity, not a race.
