A country, or a territory?

Heard Island and McDonald Islands is not an independent country but a territory. It has its own name, its own borders and often its own laws, but another country speaks for it abroad — it holds no seat of its own at the United Nations, for instance.

That is more common than it sounds. There are dozens of such places around the world: some sit far from the country they belong to, some right beside it. A few govern themselves almost completely and hand over only defence and foreign policy; others are held more closely. How much a territory decides for itself is settled case by case, never by one rule.

On this site territories get a page of their own, because children look them up and because other pages link to them. They are left out of the record lists, though: those rank only members of the United Nations, so that a ranking never mixes countries with places belonging to somebody else.
