This is something I should know, but genuinely don't.

This is something I should know, but genuinely don't. I've lived half my life in Britain and half my life in Nigeria. I feel 100% British and 100% Nigerian. I know that I can describe myself as just British or just Nigerian, but if I'm going to hyphenate it, what determines which comes first? When I'm in Britain, am I Nigerian-British or British-Nigerian?
