Did you read the sources you quoted? If I'm interpreting your intention correctly, you are trying to show how a cultural change has led to more violent crime. The point the BBC article makes is:
"In Sweden there has been this ambition explicitly to record every case of sexual violence separately, to make it visible in the statistics," she says.
"So, for instance, when a woman comes to the police and she says my husband or my fiance raped me almost every day during the last year, the police have to record each of these events, which might be more than 300 events. In many other countries it would just be one record - one victim, one type of crime, one record."
The thing is, the number of reported rapes has been going up in Sweden - it's almost trebled in just the last seven years. In 2003, about 2,200 offences were reported by the police, compared to nearly 6,000 in 2010.
So something's going on.
But Klara Selin says the statistics don't represent a major crime epidemic, rather a shift in attitudes. The public debate about this sort of crime in Sweden over the past two decades has had the effect of raising awareness, she says, and encouraging women to go to the police if they have been attacked.'
The other article (trendrr?) has a similar statement, but also quotes some numbers about increased instances of rape by muslim immigrants in 2013. This statement is unsupported, if you have some other source that gives an indication where this data comes from that would be helpful. It's not clear from the sources you have provided whether there is any like between immigration and high instances of reported sexual assault. There's some breakdown of figures here:
