Nationality is pretty easy, just look at someones passport. Ethnicity is much more difficult.

Did nations exist before passports? What is I don't have a passport? If I hold a passport for a nation that no longer exists, what nationality am I?
Well, the idea of nation states isn't that old. Passport are pretty recent, in their current form at least. And a person can be nationless, in which case they would be eligible for a UN passport.
