"The Sami people live in Norway, Sweden and Finland."
Translation:Samerna bor i Norge, Sverige och Finland.
When we’re talking about a people, i.e. an ethnic group or so, we don’t use that construction. Människorna means ”people” as in ”persons, human beings” and not as in an ethnic group. When we talk about a people, we just say like ”svenskarna” (The Swedes) or ”samerna” (The Sámi). You could also say ”det samiska folket” (the Sámi people), but it sounds very formal or unnatural.
