There has been a lot of discussions around an increase in Sweden's rape crime and it has been suggested that it was due to loose immigration policy.
I cannot find any of the data for rape in Sweden in 2016, let alone data suggesting the offenders were any of the 100'000 new immigrants. In fact, a Redditor suggests that the Swedish government refuses to study the correlation between rape and ethnicity.
So my question is:
Has there truly been an increase in rape in Sweden in the last few years and is there any evidence that this is caused by immigrants?
Please provide evidence to back up your responses.
