Switzerland:

>In 2010 for the first time was a statistic published which listed delinquency by nationality (based on 2009 data). To avoid distortions due to demographic structure, only the male population aged between 18 and 34 was considered for each group. From this study it became clear that crime rate is highly correlated on the country of origin of the various migrant groups. Thus, immigrants from Germany, France and Austria had a significantly lower crime rate than Swiss citizens (60% to 80%), while immigrants from Angola, Nigeria and Algeria had a crime rate of above 600% of that of Swiss population. In between these extremes were immigrants from Former Yugoslavia, with crime rates of between 210% and 300% of the Swiss value.[9]
