Big part of Europe is missing (Ukraine, Russia, Belarus, Kavkaz...). But for some reason it includes asian part of Turkey, islands, part of south america... ;-)
The South America / islands and included because they are territories belonging to a EU country (France, Spain, Portugal). Turkey is in there because it's a candidate country.
It's still a candidate. It's moving backwards rather than forwards on its acceptance criteria, and realistically won't be joining anytime soon, but it's still a candidate.
It's not really a question anymore for the next few years (or decades). Official status is just a political tool by now and even then this classification may lag behind.
