United Kingdom Census Persians And The UK Census?

Persians and the UK census? - united kingdom census

Well, I'm American and I'm 3 / 4 of Iran, 1 / 4 of America (Ireland). I usually complete the census, something like "white", but I hear that in England is different. I know it really should not take any role, but I am sorry for any reason, as I know, because all my friends are white Europeans led reading means that the white man. Here is a list of ethnic codes:

I do not know if I'm going to write "White Other", "blend of Asia" or "black".
