But from the Turkish point of view there's a no man's land (or British base) all along the border, so they don't touch, not even in the capital where they're a few metres apart.
luxembourg(4th), switzerland (6th) denmark(11th), netherlands(16th), austria(17th) they are all higher in rankings (in that order)
Followed closely by Belgium ((22) and france(24) and then czechia (40) and lastly poland (58)
So they are right in the middle, 4 of the countries that they share a border with have higher gdp per capita, and 4 have lower.
So the argument that it is GDP per capita, and PPP, though not incorrect, is invalid, because it would have had to have shown more than double its real GDP to be above south korea.
People are more widespread in ireland than the UK. The Uk density /km² is about 270 for the UK and only 70 for ireland. (65 million people versus 5 million approxomately)
Belgium borders all the others;
The Netherlands only borders Belgium;
Luxembourg & France both border all the others except the Netherlands.
And then St Martin comes in to ruin your day
edit: That said, the best data I could find puts Kuwait still slightly ahead ($51,000 to $50,100), so it could also be an oversight/ but Quizmaster may have better data than me.
