would it be possible to get a representative sample from Scandinavian regions , say 1000-2000 respondents?
Welcome to the forum abinet
I am afraid that as far as I know, representative samples are only available in the UK and US.
You could attempt to make a representative sample by using racial/demographic statistical data from Scandanavian countries.
However, if you make a draft study, choose the prescreen option and add screener for nationality then you can see how many participants there are in each Scandanavian country and I am afraid you’ll find the numbers are insufficient.
Ben Zeigler, a kind researcher, posted the number of participants in all countries to the forum recently.
