Cantankerous grump
I could not find it either, but while looking for it stumbled across this poll conducted by IPSOS in April 2018. It was titled "Attitudes towards Socialist Ideals in the 21st Century". The first question was: Do you agree or disagree with the following statements: - at present, socialist ideals are of great value for societal progress? 51% of Swedes agreed.I went looking for the poll that had only 9% of Swedes identifying as Socialists, but all I could find are articles mentioning the poll.
This is not evidence that Sweden is a socialist country, but it does show that a slim majority of Swedes approves of socialist ideals.
