Some very interesting comparative statistics for both the US and Canada.
‘Societal’ issues play a very determinant role in how high the murder rate is is an area.
One interesting thing to do is compare Canadian provinces with the US states that immediately border them. Quebec has very strict licencing and it’s own registry for all firearms, yet has murder rates identical to that of Maine, Vermont, and New Hampshire and those (especially Vermont) have very casual firearms laws as a contrast. Vermont has never required a permit to carry a handgun open or concealed and is one of the least violent places in the West.
When one backs Detroit’s black on black violent crime (including homicide), you would likely have Michigan’s homicide rate not terribly dissimilar to that of Ontario’s. You could probably reach similar results with Wisconsin (by backing out Milwaukee’s black violent crime) and Minnesota (with the Twin Cities’ black violence as well). Other states like North Dakota, Montana, Wyoming, Idaho, and Washington (excluding Seattle’s black violence) have rates quite similar to Manitoba, Saskatchewan, Alberta, and British Columbia. And again, these are more states with fairly permissive laws compared to certain other areas of the United States.
