Fwiw, some foreign-born numbers: 15% of the Swedish population is foreign-born. Of those, about 1/3 were born in another EU country, who are immigrants but not really what the current controversy is about (the largest single foreign-born group in Sweden are from Finland, constituting about 1.5% of the population). The remaining 10%, born outside the EU, are what "immigration politics" is mainly talking about. (The comparable figure for Denmark is a bit lower; around 5-6% of the population are born outside the EU.)
