Wikipedia: "Auckland has a population of 1,413,700, which constitutes 31 percent of the country's population." And no other country is within 1000 km.

Thanks - on a similar quiz I recently did, Auckland has the same problem and this was pointed out to me. In the data I used, Auckland is "divided" in 3 or more cities, so this is why it doesn't appear. I'm sure what you're saying is correct, there's probably many other mistakes, too, but I'll just stick to the data as it is since I wouldn't be able to find and fix all mistakes anyway
