How we count South America
We count the twelve sovereign states of South America, all of which are UN members. French Guiana is not on the list — it is an overseas region of France, not an independent country, so it is counted with France (Europe). The Falkland Islands are a British overseas territory, not a sovereign state, and are likewise not counted. There are no observer states or microstates to add.
