trying to come up with a data standard for the concept of 'ethnicity', mostly based on the values in the medical records I have access to. It's an interesting hodgepodge of a concept, mixing national origin, language tradition & in some cases religion (or maybe subculture)
I recall when I was asked my ethnicity by clinic staff I said "German/Irish", which harks back to my grandparents.
Embarrassed to see now that the modal response so far as been 'American'. That's what I am really.
