According to Gallup, gun ownership between 1999 and 2009 has remained between 40 and 45%.
According to the CDC, non-firearm related suicides have been increasing from 4.52/100K in 1999 to 5.92/100k in 2009 while at the same time, suicide by firearm has remained fairly constant between 5.95/100k in 1999 and 6.10/100k in 2009. Looking at the chart below, you can see that the number of non-firearm suicides is catching up to the number of firearm related suicides
Let's compare firearm ownership rates v suicide rates for different countries.
Clearly, there is no correlation between firearm ownership and suicide rates. (note: firearm ownership is per 100 whereas suicide rate is per 100K). The United States has approximately 270,000,000 firearms in the hands of the civilian population with a suicide rate of 11.8 which is similar to the suicide rate of Canada, but Canada has about 1/3 of the rate of firearm ownership with only 9,950,000 firearms in civilian hands. Just so you don't have to do the math, the United States has 27 times MORE firearms than Canada with nearly the same suicide rate. Obviously more firearms do not equal more suicides and looking at the chart, it appears that not having access to firearms actually leads to more suicide.
The next time some anti-rights bigot tries to tell you that more guns means more gun death, tell them to pound sand and send 'em this way.
What other comparisons can I make?
