I'm one tenth British. And most people are part British due to the colonization by the English. With many colonies, territories, dominions and trading posts around the world, the British empire covered more than 33,700,000 km2 (13,012,000 sq mi), almost a quarter of the earth's total land area and held 458,000,000 people, one fifth of the world's population.:pomp: Hope you had a fun history class today. :>
Northern Ireland? As that is located within the UK. So, 75% what? Or, is it a mix? Psst, I too am 25% Irish. 75% Scottish.
I'm Scottish, Irish, and I live in Canada where we still are a colony of GB (well my area at least) but I am francophone as well, what am I O_o
