Big Gun Data

Gun Facts Posted on by

We normally don’t post a blog entry for a single academic paper, but this one is important because it is the largest well-conducted survey concerning gun ownership and self-defense with guns (as well as other topics) to date. The survey size makes most of the data unassailable, and thus “gold standard.” Take-aways 54,000 people contacted, 16,708 gun owners within that group. Low-side concurrence with other surveys concerning defensive gun use (DGU). New insight into public carry and self-defense, both public and private. Scale data for assault weapons (AR-15s specifically) and magazine capacities more than 10 rounds. Why this paper matters Much of what we know about guns has some limitations:

Culture, Homicides and Violence

Gun Facts Posted on by

Who is more likely to shoot you, an NRA member or a member of the Crips? The primary difference between these two groups is culture. NRA members tend to be law-and-order types, whereas Crips (or members of any garden variety American street gang) are rather indifferent or openly hostile to laws. It is the adherence to a social norm – in this case, obeying or not obeying the law – that influences one’s probability to act violently, which in tern means using a gun to commit unilateral violence (e.g., not self-defense). We saw this in one study that details the propensity of people in poor and crime-ridden neighborhoods to get and use guns for criminal activities. But what cultural norms influence such behavior? We found a cross-national survey of culture and wanted to see if we could map similarities between nations concerning culture, violence and guns. The Main Take-Aways Gun … Continue reading →

Guns Not Used in Crime

Gun Facts Posted on by

What portion of America’s guns are used in crime? Somewhere between 0.00001% and 0.00477%, depending on the type of gun and crime. Take-aways Due to the repeat offenders, some guns get used in multiple gun crimes. Omitting likely crime repetitions, the number of guns in circulation used in crime drops. The combination of all gun types and the two major gun crimes means a mere 0.00477% of the gun supply is being used in crime. Multiple Uses, One Gun For years people have been taking estimates of the number of guns in public hands and dividing that into the number of gun crimes committed each year, to get a rough guess as to whether being “awash” in guns creates a problem. Typically, these rough takes estimate that less than 1% of guns are used in a crime any year. The problem is that this is a radical over-estimate. We know … Continue reading →

Incarceration, Handguns and Homicides

Gun Facts Posted on by

“The homicide rate is going up because there are more guns!” That was a hysterical statement made by a talking head on a television news network. Sadly, this fellow is considered to be a journalist by people who evidently don’t own dictionaries or know of Edward R. Murrow. At the Gun Facts project, we pour through so much data that recognizing low grade equine effluvium, such as the statement above, is second nature for us. Yet our joy in life is converting hard numbers into knowledge and perspective so that people with high intellects (that would be you, kind reader) will see through such comical statements as what the nightly news anchor uttered. The basic take-away Starting in the early 1990s, after two decades of steadily rising violent crime rates, all forms of crime started dropping. This includes homicides. But after 1993 (more on that in a moment), while the … Continue reading →

Crime Leads Gun Buying

Gun Facts Posted on by

Which came first, the crime or the guns? Statistically, crime rates appear to precede gun sales … and for some obvious reasons. Main take-aways In 29% of states, there is a significant correlation between firearm homicides and gun sales. In the top half of states, per raw correlations, 85% have firearm homicides preceding gun sales. Lead/lag times of one to three years shows 22–28% of states having crime leading gun sales, and between 6-11% of states having gun sales leading crime. The Basic Debate The basic debate surrounding whether gun sales lead to gun crimes is kinda stupid.

Background Checks and Homicides

Gun Facts Posted on by

If retail gun purchase background checks are any indication, sales of guns may keep some crime down. Backgrounds Checked The Bureau of Justice Statistics (BJS) recently released a report on background checks. Though not every state was covered, the 40 reported gives of an unexpected view into homicides and recent gun sales. But before we dive in, here is the list of caveats: Only looks at 2016/7 data, so a snapshot in time. Gun sales may lag behind changes in local violence, so there is an unspecified lead/lag issue. Since the BJS also tells us that a minimum of 40% of crime guns come from street sources (not subject to background checks), looking at retail checks and crime might produce weak results anyway. Up, Up and Away Between 1999 and 2017, the U.S. population rose 16% while the number of background checks for gun purchases rose 99%. Clearly, America has … Continue reading →

Ghost Gun Gong Show

Gun Facts Posted on by

“Criminals are taking advantage of this loophole to obtain guns that are later used in crimes.” In California, perhaps. Elsewhere “ghost guns” are the “assault weapon” for the new millennium… rarely used, marginally worrisome, and perhaps a byproduct of strict gun control laws. The Summary Data Worst case, 1.7% of crime guns are DIY (e.g., “ghost guns”). But when the top six outlier cities (all in California) are excluded, the rate drops to 1.1%. 34% of agencies recovered no ghost guns. This compares to 8% of crime guns that have no visible serial numbers (obliterated + DIY). California is the primary state having DIY guns in circulation, averaging 8% of crime guns. What We Did to Tally DIY Guns used in crime We sent public records requests to the top 100 police agencies in the United States and asked them to tell us for 2019: How many crime guns were … Continue reading →

Gun Ownership RANDomness

Gun Facts Posted on by

The Rand Corporation does a lot of interesting stuff. So, when they studied household gun ownership rates, we at the Gun Facts project took note. And we sadly note that this is not Rand’s finest work. It really isn’t even presentable. Normally we try not to go too deep into minutiae on the Gun Facts blog, mainly reserving it for more groundbreaking observations (such as when we untangled the “cattle pen scenario” element of mass public shootings or dove deep into what, if any, impact “high capacity magazines” had). But today, we will have to guide you through some perspective on gun ownership rates and show how Rand seems to have muddied the political waters. Why we need to know state-level gun ownership rates The lack of perfect knowledge about household gun ownership rates by state has annoyed criminologists and social scientist for decades. Since most American states do not … Continue reading →

Suppressed Perspective

Gun Facts Posted on by

“He had a suppressor? That’s unique.” This was from a Gun Facts fan email during the breaking news cycle of the mass public shooting in Virginia Beach. The point being made was that by his reckoning, firearm suppressors were not often used in mass public shootings (MPSs). Fact is, they are not used in crimes much at all, which makes the desire of some politicos to ban suppressors an amusing example of uninformed policy pontification. Major Takeaways BATF traced 97 suppressors in all of 2016. This is 0.01% of those in circulation. Suppressors are ignored by criminals for the same reasons they rarely use derringers or machineguns. What the BATF Tracked We used 2016 for this review of suppressors for the reason that it is recent, we could get other crime data easily, and it skipped 2017 when there was a mass BATF trace of suppressors recovered in one state, … Continue reading →

Red Flags

Gun Facts Posted on by

Are red flag laws effective, or should politicians be flagged for being offsides? Take-aways Too few data points for statistical robustness Largely irrelevant to homicides Barely effective on suicides For suicides, “studies” thus far count only “firearm deaths” instead of all forms of suicides, which is a grave methodology error Trade-off between a few lives saved and significant due process questions is out of balance Wave Your Flag “Red Flag Laws” (RFL herein) are all the rage these days, with many states enacting or considering them. However, the relative newness of RFLs makes analyzing their effectiveness a little tricky. Before 2016, only two states – Connecticut and Indiana – had RFLs. To see before-and-after effects of any law, you need a little runway (we at the Gun Facts project think ±5 years is sufficient). Most states with RFLs have less than three years of experience with these laws. So, with … Continue reading →
