Interesting quiz idea. Those are some amazing statistics even for the countries at the bottom of this scale in my opinion. Monaco's is just mind blowing. 3.3 billion dollars per square km?!

Yeah, that's actually a really interesting case--since Monaco's total area is about 7/9 of a square mile, their GDP/SqMi is actually more than their GDP.

I don't think the Vatican produces anything, they rely on incoming income.

I've been to Malta and every square inch seems accounted for but I had no idea they were so productive. Tourism maybe?

Malta is a hub for financial services and gaming. And of course, tourism plays a major role!

Missed the islands because started guessing those only as time was running out and didn't have a clue in which order to guess. Nice one.

I am stunned that Brunei isn't on here. Small country, and I thought the Sultan's wealth alone would be enough to have them make the quiz.

I guessed Brunei too, I wonder if it is because the wealth is focused in one household and the rest of the people are dirt poor? Amazed to see Malta made the list, just started guessing small industrialized countries. Very good quiz, makes you really think. I hope there are more.

Most probably that wealth doesn't generate any GDP. Having a lot of capital and using that capital productively aren't the same thing.

Brunei has the 5th highest per capita GDP in the world, so that's certainly not the problem. The issue is that it is too sparsely populated - only ranked 142 in the world for population density. The populace is extremely wealthy, but relatively spread out (compared to the rest of this list).

interesting to see uk on the list, but actually most of the wealth generated is in the south-east and london. Those two combined would be $61M/km^2 (using GVA) and london on its own would be $208M/km^2. New York's $1.4Tn translates to a ratio of $1154M/km^2. Even in that context Monaco really is high. Is there a version of this for metropolitan areas?
