Ireland's figures are wildly unbalanced compared to other EU countries because so many companies decided to formally register their headquarters there. They don't pay as much tax as they should so the income stats are way up there but the positive effects are not as you might expect from that (if they weren't actually negative).

This is now mostly a thing of the past but there are still lingering after-effects.
