Yeah, BlueTrain, economy of scale doesn't quite fit, but I think it gets the point across.
Stats and Studies about crime are always a bit wishy-washy. For example, they never give the specifics. Was the one murder in your home town the result of domestic strife? If so, one could say that your chances of murder were zero, unless you were married to Mr. X, at which point they would be 100%!
Of the 22 murders in the large population where you live now, how many were committed by strangers against strangers? That would be a better stat, with more meaning.
Anyway, I hope the OP has fun with his research.
