It originally used the term “Iberian Peninsula” back when it still called me things it now says I am not. Now it says “Spain”, listed as an ethnicity.
10% Iberian Peninsula was surprisingly in my first result, then a revision eliminated that and a couple other small percentages. The revised one is more what I expected, Great Britain, Ireland, etc., Northwestern Europe and Norway.
Maybe they say Spain because too many have no clue where the Iberian Peninsula is located.
