Their small population and small area means they have little effect on the countries bordering them. It means you're looking for bordering countries which are dense, but also similarly sized (or the large one is dense like India).

So for Vatican and Italy, despite Vatican having a density of like 1600, when adding its area to Italy's area, and its population to Italy's population, it makes no difference!

Means you get very different results to my "densest bordering countries" quiz :)

I just remembered the African countries with less 10 seconds on the clock. The quiz was very fun!

Another great quiz! I just came from the other quiz with the other way of calculating, and it’s interesting looking at them side by side.
