Thank God for my helpful readers.
Last time around, thanks to commenter TS, we were able to integrate importation numbers into the "graphics matter" series of posts, which only served to perforate the "more guns = more deaths" hypothesis even worse. Unfortunately, though, Shooting Industry Magazine rearranged their site sufficiently that some data was apparently lost, and I had to drop the 1981-1985 section of the graph due to not being able to adequately source my numbers; I will leave the wholesale fabrication of statistics to the "gun control" extremists.
This time around, Hoplophobic Healer reminded me that the WayBack Machine does exist, and after digging around its guts for a few minutes, I was able to find this archived page documenting firearm production from 1982 until 2001 (said page screencaptured to the right, just in case it tries to disappear too). Unfortunately, the Shooting Industry Magazine did not track imports that far back, but at least we have domestic production numbers again, and based on that, I have decided to go ahead and add the 1981-1985 section back to the graph.
For reference, the 1981 year was chosen for the lower bound of this graph simply because WISQARS Injury Mortality Reports do not go any farther back. I know there are sources that do go farther back, but then you run into the question of whether or not they track their information the same way WISQARS does, and that just throws this whole graphic into question. (And, yes, I am well aware that WISQARS changed how they code their data between 1998 and 1999, but if you look into the explanations of what all they changed and why, none of it really affects the numbers we are looking at.)
So enough of this jibber-jabber, right? As with before, all previous disclaimers, details, and other important stuff still apply, including using the Shooting Industry Magazine as a source again. Now, on with the show:
I am again going to dispense with the acres of text, and instead consolidate it all down to this disclaimer: you CAN compare the correlation coefficients in this dataset to the correlation coefficients in the previous 1981-2009 datasets, but NOT the 1986-2009 one I put up last week. Y’know, just to make things more confusing. Things, of course, did change with the re-inclusion of those five years, which is why I always maintain that more data is more better:
The raw number of firearms in America correlated to the raw number of firearm-related fatalities with a coefficient of -0.41741, which is a little stronger than before including the firearm importation numbers.
The rate of firearm ownership in America correlated to the rate of firearm-related fatalities with a coefficient of -0.80373, which is significantly stronger than before.
In other words, what I said before only continues to hold true: the hypothesis "more guns = more deaths" cannot be true in the fame of reference of American society over the past almost-three decades.
Again, unlike the anti-rights cultists who are currently weeping into their bourbon at the sight of those numbers, I am more than happy to show my work – after all, if I did not, I would never have you kind people to thank for filling in the holes I made.
