F1 wins by country per 1 million people
Arguments to be had over definitions here regarding Ireland! Eddie Irvine (4 wins) raced under the British nationality but he lived in Ireland and had an Irish racing license. He was listed as an Irish driver in 1995 and 1996, had an Irish flag and Irish national anthem playing on the podium at some races in 1995/6/7 (but British at others), and has said that he himself identifies as Irish rather than British.
So it’s all very confusing.
