The Problem of Mass Shootings

The recent years have brought about much gun violence in America with mass shootings frequently dominating the nation's headlines. Mass shootings such as the Orlando Nightclub and Sandy Hook Elementary School shootings are closely associated with the issue of gun violence.

While there is no universal definition of a mass shooting, we use the definition "FOUR or more shot and/or killed in a single incident, at the same general time and location not including the shooter" which is similar to the FBI's definition of a mass killing, which does not specify a weapon type.

Using data on mass shootings kindly provided to us by the Gun Violence Archive, a not-for-profit corporation dedicated to providing accurate public access to gun-related violence in the United States, we present an overview of some of the numbers surrounding mass shootings from 2013 to 2016.

...But there is more to it than just Mass Shootings

Because of the sheer number of victims in a single incident, mass shootings have been heavily covered in the media. However, the number of deaths by mass shootings only account for a small fraction of the total gun deaths in the United States.

In 2015, 0Americans died from gun related injuries
Each
represents 100 deaths
Out of the 36,252 deaths caused by gun-violence, 334 of these deaths occured in a mass shooting.
Over the past decade, from 2005 to 2015, the number of gun deaths has risen to become fairly similar to the number of deaths caused by car accidents. In contrast, the number of Americans killed in terrorist incidents pale in comparison.
Across other high-income countries, based on their Human Development Index score, the United States ranks the highest in number of gun deaths per 100,000 people.

Understanding the Circumstances

Breaking down the data further can give us a more nuanced understanding of who the victims are and where these crimes are perperated. In this visualization, we break down the data for 2015 into 1 or 2 variables which can reveal deeper insights into the circumstances and factors surrounding these tragic events.

    Suicide accounts for the largest proportion of gun deaths among white people, while homicides make up the largest proportion of gun deaths for black people.
  • Select Age > Intent:
    Suicide accounts for the largest proportion of gun deaths among the 40+ age group, while homicides make up the largest proportion of gun deaths among those aged 20-29.
  • Select Education > Intent:
    Suicide accounts for the largest proportion of gun deaths among those holding some degrees, while homicides make up a larger proportion of gun deaths among those without one.

What is the state of firearm regulations in the United States?

Laws exist to ensure general safety and to ensure that our rights as citizens are guarded against abuse by others. including ourselves. Similarly, firearm laws exist to preserve both public and private safety in matters concerning the use of firearms.

While there are federal laws in place to regulate firearm activity, state and local police are not legally obligated to enforce these laws. Many states implement their own firearm laws and as a result of this, the laws in each state vary considerably. Next, we explore the types of gun laws present at the state level.
