Translation:How many Greek people live in Greece?
I am a Greek native in Hellas. Our population is around 11 million. However only 10 million of them are native Greeks. The rest 1 million, are immigrants. Also there are around 7 million Greeks in diaspora, (USA, Germany, Australia etc.) and around 1 million Greeks in Cyprus. So, in total the global ethnic group of Greeks is around 18 milliion (10 εκατ, Ελλαδίτες, 7 εκατομμύρια ομογενείς και 1 εκ. Ελληνοκύπριοι).
I'm not fluent in Norwegian so I don't know for sure but lever means leben in German which sort of refers to living as in living a lifestyle (Jeg lever i en fantasiverden). Bor means living (wohnen) for example in a house, city or country (Jeg bor i Norge). Hope that makes sense.
It is "Hellas" because Norwegian simply borrowed it from the native Greek word for the country (from Ελλάς~ "Ellas"). This is the "endonym" (it would be the equivalent in English of calling Spain "España" or calling Germany "Deutschland"). Interestingly/ironically, Greeks themselves rarely use this word as it is considered rather literary nowadays- the most common modern Greek word for Greece is Ελλάδα (~ "Ellada").
