Homicide and Guns in the USA, 2007:
I went to the CDC and got into their data. The most recent year for which data is available appears to be 2007, so I took only 2007. I chose the 'leading cause of death' and pulled the data only for all races, all ages, all sexes, etc. In other words, the broad spectrum.
I then drilled down to homicides; I did not include suicides. Homicide to the CDC does not mean only murder; it also refers to lawful killing. Here are the numbers I found:
Ages 1-4: 398 deaths by homicide. 48 by firearm.
Ages 5-9: 133 deaths by homicide. 47 by firearm.
Ages 10-14: 213 deaths by homicide. 154 by firearm.
Ages 15-24: 5,551 deaths by homicide. 4,669 by firearm.
Ages 25-34: 4,758 deaths by homicide. 3,751 by firearm.
Ages 35-44: 3,052 deaths by homicide. 2,038 by firearm.
Ages 45-54: 2,140 deaths by homicide. 1,159 by firearm.
Ages 55-64: 980 deaths by homicide. 446 by firearm.
Ages 65+: Not in top 20 causes of death.
All Ages: 18,361 deaths by homicide. 12,632 by firearm.
For all ages, homicide is the 15th leading cause of death. Influenza is number 8, by way of reference. Suicide is number 11 for all ages. Number 1 is heart disease, number 2 is 'neoplasms' which I think means various kinds of cancer.
It is interesting to look at the data; I encourage others who are curious to make their own studies of this.
For example, if you just look at the numbers, you see the number of homicides, as well as the percentage of homicide by firearm, rising as age of the victim increases, up to age 24. Then it begins to drop, but the numbers remain high. However, if you look at the list of causes of death, you see a different story. For ages up 34, the numbers and percentages roughly match, but after age 34, the percentage of homicides as a cause of death drop like a rock. The number of homicides may not be that much lower between the groups 25-34 and 35-44, but the number of deaths increases dramatically; but now most are due to various kinds of disease, and suicide passes homicide as a leading cause of death. It's really fascinating from a data perspective (not that death is a fun thing). By age 45, homicide as a cause of death is not even in the top ten (it's number 13). More people of that age die of diabetes - by a LOT!
Now, it can be said that in 2007, 12,632 people were killed (homicide) by firearm. What this data does NOT show us is quite important, however. It does not show us how many were killed by police or others in lawful shootings. It does not show us how many were criminals shooting each other, or shooting innocent citizens. It definitely does not give us any indication of how many were committed by people who purchased their guns legally and who therefore would presumably not have been able to kill a person with a gun if they simply didn't have one.
Many people have attempted to slice and dice data like this to make it mean many things; both pro and anti gun. I won't attempt it; I haven't the necessary data.
But I can say with assurance that there is no way to legitimately state that 12,632 people
would not have been killed in 2007 if guns were illegal. All I can say that perhaps a percentage of them would not have been killed. I do not know what that percentage is; I doubt anyone does. And in a nation of over 300 million, although I realize each death is a tragedy, I do not see the justification for banning or even further restricting gun ownership.
Take a look at the numbers yourself. The data is there, even if there are many things about it that we cannot know by looking at the raw data...it's still quite interesting.
