This was made widely public when a 23-year old who got asylum as a 17-year old killed a social worker at the asylum about a year ago, and investigation showed that at least 10% of "minor" asylum seekers at that place were above 20. Google may give you more details.
I did Google, and Google tells me Sweden wants to introduce age tests to address this issue (I hope they don't outsource it to IBM).
I disagree with your other post regarding the fact that a refugee being 16 or a young adult doesn't change much: what we are discussing here, beside the racist Predatory Brown Men are coming! thing, is the legitimate concern over the necessary cultural integration of refugees in their host country Vs becoming a problem for society. We know that a husband or dad (or a family unit in general) is much less likely to cause any trouble. That would less be the case with a young single adult, who is fully autonomous and has no dependents. A kid, even at 17, is much less autonomous, will have an educator or foster family, will go to school, etc, they are going to be 'enrolled' much more actively into society.
That's nice in theory, but it doesn't actually bear out in practice. As one example, according to [0], even second or third generations fail to integrate (with disastrous results), and AFAIK that's the rule rather than the exception (though there are quite a few exceptions, more in the UK, less in mainland Europe). It's not enough if even 50% integrate successfully when the number of immigrants is so high.

Do you really think people won't lie to get an advantage
Naivete is strong it seems
So, yes, those who expected the majority to lie about their age have been proven correct.

Just over 83% is considered to be over 18, ~1% is likely to be over 18, 16% is possibly younger than 18.
Either way, even if they are just 16, it does not change the fact that two years later, the vast majority of adult refugees are male.
The article provides statistics as recent as 2016. It does more than refute a single picture.
>> Syrian refugees - which are probably the more (perhaps only) deserving of "refugee" status
Just off the top of my head: Eritrea, Lybia, Western Iraq, Burma. And that's not counting locally displaced refugees who don't reach Western shores (Burundi, Nigeria, Yemen).
Regarding your source:
Specifically regarding Sweden, this does not really counter what I said. Your source notes that the demographic that leans (very) heavily male is unaccompanied minors (in fact it seems they account for almost all of the male imbalance in Sweden?). These are not single adult males (I used that term because the linked blog heavily relies on the "dangerous young adult" trope mentioned by Snopes -- by 'single' I mean 'not married'). Your source however does show that there are more adult males registered in Greece and Italy. Quick aside: registered refugees do not get to choose their assigned countries of residence if/when their status as refugee is recognized.
I'd say there is quite a world of difference between groups of "young adult males" and unaccompanied minors (who are in that situation presumably because they have lost their families).
>> and in fact - especially in Sweden - they are
But do you have better sources than this one which says these are boys, not men? The point of my post was that the linked blog made loaded claims without substantiating them, so I only went as far a providing a counter-point. Maybe the current Swedish government does in fact have a policy locally favoring male refugees directly or indirectly (which in absolute is possible since, as noted above, refugees don't get to choose where they end up), but he provided no evidence.
