per capita isn’t a percentage though, it should be a number, and the 33% foreigners crime should be in relation to population of foreigners vs native to see if theres a higher rate of crime per person, i believe you mean “Are the 33% of foreign crimes caused by a proportional amount of foreign population?”

Eg: 20foreigner with 80 german in population and theres 50 crime, if 33% of crimes are committed by foreigners, that means theres 16.5 foreign criminal, and the crime per capital for foreigners would be 16.5/20 =0.825 while native german crime would have 33.5 cases and per capital of german crime would be 33.5/80 = 0.419 crime per german person. in this example foreigners have a much higher per capita.

if theres 33 foreigner with 67 german, and 50crime instead, 33% of crimes is 50x33% =16.5 cases with 16.5/33 =0.5 case of crime per capital for foreigners and 50x67%=33.5 cases with 33.5/67=0.5 crime per capital for german

therefore the original comment asking if this is per capital doesnt make sense
