Last year there were something like 14,000 murders in the U.S. There are also many countries that have less than 100 murders a year. There’s no way that those four cities account for more than 1,500 murders.
had a chance to look at the numbers posted on the linked Wiki article and also looked up some numbers for the cities in the OP…Interestingly the 2010 numbers by state for 2010 showed a total of 9403 gun murders nationwide. The city numbers were from 2011 and for the 4 cities listed in the OP the total was 1082. Not sure how this might effect your calculation Marty…but there is the info as I have it.
I then checked the cities against their individual state totals. Of course DC doesn’t fit in this…and the 2010 total for Illinois was less than the 2011 total for Chicago alone.
However in the other two cities, New Orleans accounted for 57% of the state total while Detroit accounted for 83% of Michigan’s total.
Checking the murder rate - City vs Statewide bears this out. Look at the disparity in the rate per 100,000 in the given city vs the state as a whole.
Chicago Rate 15.9
Illinois 2.8
New Orleans Rate 57.6
Louisiana rate 7.7
Detroit Rate 48.2
Michigan Rate 4.2
Now compare those to a state that is arguably one of the most “armed” in the nation…Alaska.
Anchorage Rate 4.0 Alaska 2.7
Or how about another state that is noted for it’s love of Guns…Texas.
Dallas comes in at 10.9 and Houston at 9.2 with a statewide rate of 3.2
Interestingly enough - looking at the Brady Scores (higher number = more restrictive)
Illinois rate =35
Louisiana rates = 2
Michigan rates = 25
Alaska Rates = 0
Texas Rates = 6
To me this at least validates one idea contained in the OP statement. That the majority of Gun deaths tend to be concentrated in a certain few areas and also that more restrictive gun laws do not correlate to fewer gun murders.
