DN.se made an article(2013-06-13) about immigrants contributing economically more than the cost. Immigration is a very hot topic in Sweden, and Sweden have a very high number of refugees.
In 2009, Sweden had the fourth largest number of asylum applications in the EU and the largest number per capita after Cyprus and Malta.
The question is, does this study take into calculation all costs related to immigration, or is it just parts of it? Is there any difference between work-immigrants and refugees in the contributions?
It seems like the stats is too good to be true, and it's commonly said that immigration is breaking down the welfare of Sweden, and that Sweden is going downhill. It's popular stance enough for a racist discontent-party to get voted into the government. I would be interested in an objective and statistics based critical examination of that.
The data the article in DN is based off is from OECD, and the short version is in a picture below, while the full report is linked to bottom of the question.
