I'm born in Poland to Polish parents, but all their parents were born Germans. I moved to Germany when I was 11 and when someone asked me then I said I'm German. But then I moved to Sweden for 15 years, while there I would also say I'm German. I got the Swedish citizenship but you still can hear that I'm not a native Swede, but only Swedish people can hear it. So once I moved to Korea 4 years ago I used my Swedish passport to get in to the country (it was not on purpose but random chance, I could have chosen the polish one or the German one too). Anyway, if someone in Korea asks me where I'm from or what I am I almost always say I'm Swedish. with one exception, if a German here in Korea asks me then I say I'm German.

I know it's a bit easier for me because I look like I could be from any of those countries, but my identity is not tied to some specific geographic area so I have no problem being a geographical-identity-cameleon.
