That's nominal, severely outdated, and severely misleading. Ireland is the third richest [1] country in the world on paper as far as GDP/capita PPP measures, while in reality the household income/capita is a small fraction of that. The reason their GDP is so high is that hundreds of multinationals (including Google, Facebook, Apple, etc) filter large sums of money through Ireland in tax avoidance schemes. It's one of the best examples of how GDP is a very silly metric.
Incidentally, it's also the only country in the EU with a higher GDP/capita than the US.
