How does the idea of race, ethnicity, and nationality impact one another?

in at least two sentences. just the ideas impact one another, nothing about people in them.

They impact each other because they are commonly connected when describing society. Commonly, the idea of the same race and the same ethnicity implies that the people belong to the same nationality, however, in recent times ethnicity and races started mixing more and more as we have the culture of globalism and multi-culturalism.

If this is a true or false question the answer is true.
