"Skandinavien", is that the definite article form? I ask because of the -en ending. Would that be used in this sort of grammar structure?
"Scandinavia" is a rather cumbersome concept since people have different opinions of what it means. Here in Sweden, people usually talk about Sweden, Norway and Denmark, but some want to include Finland and some want to exclude Denmark.
Scandinavia is rarely used as a concept in Scandinavia. To me, it feels more like something Americans talk about...
We prefer "Norden" or the Nordic Region because everybody agrees on what that is.
