Interesting. From the Internet:
> 1. The original and locally preferred view is that Iceland, Finland, Faroe Islands, and Greenland are all countries considered to be part of the Nordics, but not technically part of Scandinavia (which would only be Sweden, Norway and Denmark in this case).
> 2. The international and more commonly preferred view is that the Faroe Islands, Finland and Iceland are part of both Scandinavia and the Nordics, leaving Greenland as the only non-Scandinavian country in the Nordics (along with the Norwegian territories of Svalbard, Jan Mayen and Bouvet Island).

I don't think it the more common perspective outside of Scandinavia either. It is common, but lots of people from outside the Nordics are perfectly aware that it annoys us.
In the Nordics the terms are not just "preferred" but unambiguously used this way.
