it is the difference between asking a random person on the street how many types of birds there are, and someone that has studied birds all their lives. The second person might still be off by a bit, but will come closer to the truth than the random person, that would just pluck an answer out of thin air. (and more accurately, it is the answer agreed upon, that rolls out of the discussion of many birds enthousiasts on the matter)
Really makes the American inside me have to learn the metric system :P
The UK has Northern Ireland, while China doesn't have any portion of Taiwan. And for Antarctica, there is a treaty that doesn't recognize any claim on the continent. And it's a continent, not an island, so it doesn't matter here anyway.
