I don't have any, as said in my reply to beagle3, I was commenting on an article that was making claims about Sweden without showing data. And the data I found, which is more general, does contradict his claim.
Regarding the refugees entering Europe: initially something like 90% of refugees were in Turkey/Lebanon/Jordan, but the camps there started to crumble under the demographic pressure and lack of funds, and people started a westward migration. Most people arriving in Greece are in fact coming out of Turkish refugee camps, as far as I know. So Europe saw its number of refugees double from 10 to 20% in pretty much one year, and it's not really known if the deal with Turkey will stabilize this number.
Your source is better than mine and does show an imbalance in the adult demographics applying for refugee status in Europe, but it is still lacking enough details to support a "single adult males storming the gate" hypothesis: according to the Snopes article most "entering-the-EU-as-single" male refugees are married or part of a family but cross over to Europe alone to apply for the status and then bring their family in later, officially and through non shady/dangerous routes. It makes sense that they would temporarily leave their family in the relative safety of established camps, and the fact that there is no male-leaning imbalance in the overall refugee population supports this. I can't find the source for this but in general "unmarried/alone young adult males" represent a small amount of the overall refugee population [1].
I will also point out again that refugees are in fact "applicants", and once accepted do not choose in what country they end up. If Sweden ends up with a disproportionate number of young men, it will be because of a policy decision, not because they walked in a settled there. Case in point: Canada is taking in plenty of refugees, but not unmarried adult men: https://www.theguardian.com/world/2015/nov/24/canada-exclusi...
[1] There is this piece by Samantha Bee: https://youtu.be/na7pFnoLxjw?t=3m6s saying it's about 2%, but it's about the US and they provide no source, and I suspect a refugee expert being interviewed on a liberal show will not be accepted by some.
