How many mass shootings occurred in the United States in 2015? It seems like a relatively simple question; it sounds like just a matter of counting them. Yet, it is challenging to answer for two separate reasons: one is related to how we define mass shootings and the other to reliable sources of data on mass shootings. And neither of these challenges have easy solutions.
As scholars and teachers, we need to think about the kinds of events we should and should not include when we make claims about mass shootings. Earlier this year, we posted a gendered analysis of the rise of mass shootings in the U.S. relying the Mass Shootings in America database produced by the Stanford Geospatial Center. That dataset shows an incredible increase in mass shootings in 2015. Through June of 2015, we showed that there were 43 mass shootings in the U.S. The next closest year in terms of number of mass shootings was 2014, which had 16 (see graph below). That particular dataset relies heavily on mass shootings that achieve a good deal of media attention. So, it’s possible that the increase is due to an increase in reporting on mass shootings, rather than an increase in the actual number of mass shootings that occurred. Though, if and which mass shootings are receiving more media attention are certainly valid questions as well.
If you’ve been following the news on mass shootings, you may have noticed that the Washington Post has repeatedly reported that there have been more mass shootings than days in 2015. That claim relies on a different dataset produced by ShootingTracker.com. And both the Stanford Geospatial Center dataset and ShootingTracker.com data differ from the report on mass shootings regularly updated by Mother Jones.* For instance, below are the figures from ShootingTracker.com for the years 2013-2015.
For a detailed day-by-day visualization of the mass shootings collected in the ShootingTracker.com dataset between 2013 and 2015, see below (click each graph to enlarge).
The reason for this discrepancy has to do with definition in addition to data collection. The dataset produced by the Stanford Geospatial Center is not necessarily exhaustive. But they also rely on different definitions to decide what qualifies as a “mass shooting” in the first place.
The Stanford Geospatial Center’s Mass Shootings in America database defines mass shootings as shooting incidents that are not identifiably gang- or drug-related with 3 or more shooting victims (not necessarily fatalities) not including the shooter. The dramatic spike apparent in this dataset in 2015 is likely exaggerated due to online media and increased reporting on mass shootings in recent years. ShootingTracker.com claims to ensure a more exhaustive sample (if over a shorter period of time). These data include any incidents in which four or more people are shot and/or killed at the same general time and location. Thus, some data do not include drug and gang related shootings or cases of domestic violence, while others do. What is important to note is that neither dataset requires that a certain number of people is actually killed. And this differs in important ways from how the FBI has counted these events.
Neither ShootingTracker.com nor the Stanford Geospatial Center dataset rely on the definition of mass shootings used by the Federal Bureau of Investigation’s Supplementary Homicide Reporting (SHR) program which tracks the number of mass shooting incidents involving at least four fatalities (not including the shooter). The table below indicates how different types of gun-related homicides are labeled by the FBI.
Often, the media report on events that involve a lot of shooting, but fail to qualify as “mass murders” or “spree killings” by the FBI’s definition. Some scholarship has suggested that we stick with the objective definition supplied by the Federal Bureau of Investigation. And when we do that, whether mass shootings are on the rise or not becomes less easy to say. Some scholars suggest that they are not on the rise, while others suggest that they are. And both of these perspectives, in addition to others, influence the media.
One way of looking at this issue is asking, “Who’s right?” Which of these various ways of measuring mass shootings, in other words, is the most accurate? This is, we think, the wrong question to be asking. What is more likely true is that we’ll gather different kinds of information with different definitions – and that is an important realization, and one that ought to be taken more seriously. For instance, does the racial and ethnic breakdown of shooters look similar or different with different definitions? No matter which definition you use, men between the ages of 20 and 40 are almost the entire dataset. We also know less than we should about the profiles of the victims (those injured and killed). And we know even less about how those profiles might change as we adopt different definitions of the problem we’re measuring.
There is some recognition of this fact as, in 2013, President Obama signed the Investigative Assistance for Violent Crimes Act into law, granting the attorney general authority to study mass killings and attempted mass killings. The result was the production of an FBI study of “active shooting incidents” between 2000 and 2013 in the U.S. The study defines active shooting incidents as:
“an individual actively engaged in killing or attempting to kill people in a confined and populated area.” Implicit in this definition is that the subject’s criminal actions involve the use of firearms. (here: 5)
The study discovered 160 incidents between 2000 and 2013. And, unlike mass murders (events shown to be relatively stable over the past 40 years), this study showed active shooter incidents to be on the rise. This study is important as it helps to illustrate that the ways we have operationalized mass shootings in the past are keeping us from understanding all that we might be able to about them. The graph below charts the numbers of incidents documented by some of the different datasets used to study mass shootings.
Fox and DeLateur suggested that it is a myth that mass shootings are on the rise using data collected by the FBI Supplementary Homicide Report. We added a trendline to that particular dataset on the graph to illustrate that even with what is likely the most narrow definition (in terms of deaths), the absolute number of mass shootings appears to be on the rise. We do not include the ShootingTracker.com data here as those rates are so much higher that it renders much of what we can see on this graph invisible. What is also less known is what kind of overlap there is between these different sources of data.
All of this is to say that when you hear someone say that mass shootings are on the rise, they are probably right. But just how right they are is a matter of data and definition. And we need to be more transparent about the limits of both.

*Mother Jones defines mass shootings as single incidents that take place in a public setting focusing on cases in which a lone shooter acted with the apparent goal of committing indiscriminate mass murder and in which at least four people were killed (other than the shooter). Thus, the Mother Jones dataset does not include gang violence, armed robbery, drug violence or domestic violence cases. Some have suggested that not all of shootings they include are consistent with their definition (like Columbine or San Bernardino, both of which had more than one shooter).














In the panel of the cartoon reproduced here, you can see Wimberly’s original color swatch for the character alongside the swatch he was instructed to use for the character.




Now, perhaps it was unfair to use Batman as a comparison as his character is more often depicted at night than is Wonder Woman—a fact which might mean he is more often depicted in dynamic lighting than she is. But it’s an interesting thought experiment. Based on this sample, two things that seem immediately apparent. Amazing-man is depicted much darker when his character is drawn angry. And Wonder Woman exhibits the least color variation of the three. Whether this is representative is beyond the scope of the post. But, it’s an interesting question. While 




While they were allowed to select all of the possible reasons that might apply, only about a quarter of the sample cited “professional reasons” for not having children earlier. The overwhelming majority of women (88%) claimed that “lack of partner” was the primary reason (see our adapted graph).2
As such, it might not be all that surprising that a more diverse group are delaying and forgoing marriage. Indeed, as 
In The Incredibles, Bob Parr’s incredible strength and monstrous body look silly accomplishing domestic tasks or even occupying a traditionally domestic masculinity. His small car helps is body appear laughable in this role as he drives to work. At work, Bob’s desk plays a similar role. His body is depicted as not belonging there—domesticity is symbolically holding him back. This sort of “crisis of masculinity” narrative plays out in the stories of many of these characters. So, when they occupy the role they are initially depicted as denying, the narrative creates a frame for the audience to collectively experience relief as they take on the heroic roles for which their bodies symbolically situate them as more naturally suited. The scene in The Incredibles in which Bob Parr (Mr. Incredible) quits his job by punching his boss (whose physically inferior body is regularly situated alongside Bob’s for comic relief) through a wall is perhaps the most exaggerated example of this. The pleasures these films invite us to share at these moments when gendered hierarchies of embodiment are symbolically put on display play a role in reproducing inequality.
Indeed, side-kicks and villains are most often depicted as occupying masculine bodies less worthy of status. These masculine counter-types (like Randall in Monsters Inc., Sid Phillips in Toy Story, or Buddy Pine/Syndrome in The Incredibles) embody masculinities portrayed as “deserving” the “justice” they are served.
