Thanks just. Yes, Sweden (a) is much less likely to no-crime rape reports, and (b) records each incident separately whereas a lot of countries will report repeated rapes by the same perpetrator on the same victim (say, marital rape over a protracted period) as a single crime. This inflates Sweden's rape figures (as does the fact that because they take it seriously, women are more likely to report crimes to the police).
The issue over numbers of immigrants committing crimes is somewhat murkier - some websites appear to conflate numbers of convictions of immigrants with numbers investigated by the police.
The other thing that's interesting is the "Sweden has a worse gender ratio than China" headlines. I think the source for this is a blog, but one which from a quick look did seem to be based on publically available stats from the Swedish government. The thing is the figure isn't for the Swedish population as a whole, but (if I'm remembering right) the 15 to 20 agegroup specifically, because Sweden has a small population, and a large number of the refugees they've taken have been "unaccompanied minors". Which isn't to say that this gender imbalance isn't worrying, just that the headlines are misleading.
I will reiterate, as I did in the previous post, that it's very difficult to get the accurate breakdown of figures from a reputable source because as we've seen with these events it's unclear that the serious press - broadsheets, BBC, etc. - are actually doing the investigative journalism they should be, for fear of being seen as inflammatory. I would like to see someone do a decent job of this. The stats are there.
For me the main lesson from this is that the efforts of the mainstream media to try to downplay issues in order not to play into the hands of the far right has misfired spectacularly. Unless we get accurate, unbiased reporting, and an opportunity to have an open and informed debate about it, a vacuum is created which the far right can exploit.
