  • The number of mass shootings in the US this year reached 30 on Wednesday.
  • A gunman opened fire on students and staff at Marjory Stoneman Douglas High School in Parkland, Florida, killing at least 17 people.
  • There have been nearly as many US mass shootings as days in 2018.

On Wednesday, a gunman opened fire on students and staff at a high school in Parkland, Florida, killing at least 17 people. It was the deadliest US mass shooting so far this year.

The incident marked the 30th mass shooting in 2018, according to the nonprofit Gun Violence Archive, which tracks shootings in the US. To put this into perspective, we are 46 days into the year, which means the US has had nearly as many mass shootings as days in 2018.

Americans are more likely to die from gun violence than many leading causes of death combined, with some 11,000 people in the US killed in firearm assaults each year.

There is no broadly accepted definition of a mass shooting. Gun Violence Archive defines a mass shooting as a single incident in which four or more people, not including the shooter, are “shot and/or killed” at “the same general time and location.”

The government also doesn’t have an official definition. In 2013,a report from the Congressional Research Service, known as Congress’s think tank, described mass shootings as those in which shooters “select victims somewhat indiscriminately” and kill four or more people – a higher bar than Gun Violence Archive’s, as it doesn’t take injuries into account.

In 2013, a federal mandate lowered that threshold to three deaths. By this definition, using data from Gun Violence Archive, the Parkland event was the sixth US mass shooting in 2018.

Data from Gun Violence Archive also shows that more than 1,800 people have died from gun-related violence so far this year and more than 3,100 others were injured.

Here’s a complete list of the mass shootings– as defined by Gun Violence Archive – that have occurred in the US so far in 2018.
