People here in Sweden are quite attuned to both general crime rates as well as the particular factors behind those rates.
We are all happy that crime has fallen. You seem to be against it falling further?
People in Sweden want the crime rates reported separately for:
a) "sorta native Swedes" (people whose families have lived here many hundred years)
b) "new Swedes" (e.g. people who arrived last year from Somalia)
It is a well-accepted opinion that the people in category b) are grossly (by a factor of 10 or more) over-represented in crime stats.
The authority you linked to has famously denied creating fresher stats than their 2005 report on origin vs crime frequency report - simply by saying "it's not needed". This is right. Sweden hasn't extracted and published crime stats based on the perps' origins simply because the results would be inconvenient.
