Mass shootings in America are a serious problem -- and these 9 charts show just why

(CNN)There's no one commonly accepted definition of a "mass shooting." But whatever criteria you use, the conclusion's the same: There are more mass shootings in the United States than in any other country in the world.

If you go with the raw numbers ...

According to the Gun Violence Archive, which compiles data from shooting incidents, a "mass shooting" is any incident in which a gunman ...
  • shoots or kills four or more people
  • in the same general time and location
By that definition, according to the Gun Violence Archive, we have seen 307 mass shootings from January 1 to November 5.
That averages to almost 7 mass shootings a week.

Under the narrowest definition ...

The government has never defined "mass shooting" as a standalone category. Let's go with the most commonly accepted definition, from the Congressional Research Service: a shooting in which a gunman ...
  • kills four or more people
  • selects victims randomly (ruling out gang killings or the killing of multiple family members)
  • attacks in a public place
That definition rules out the Congressional baseball practice shooting in June, because the gunman didn't kill four people. In September, a man shot and killed eight people in Plano, Texas -- but that attack doesn't count either because police say the gunman had a "connection to the house."
Using that narrow definition to the Gun Violence Archive numbers, we have seen ten deadly mass shootings from January 1 to November 5.
That averages to one a month.

The five deadliest shootings in the US have occurred in roughly the past 10 years

The Las Vegas attack was the deadliest shooting in modern US history (at least 58 killed), and it's only 10 years removed from the 2007 Virginia Tech massacre (32 killed) and a year removed from the second-deadliest shooting, the Orlando nightclub shooting. November's shooting in Sutherland Springs, Texas is now the fifth-deadliest shooting, with at least 26 victims.
In fact, of the 30 deadliest shootings in the United States dating back to 1949, 18 have occurred in the last 10 years.

It's a largely American phenomenon

From 1966 to 2012, nearly a third of the world's mass shootings took place in the United States. A 2016 study looked at 292 incidents in which four or more people were killed. It found 90 of them occurred in America. Put another way: While the United States has about 5% of the world's population, it had 31% of all public mass shootings.

People have a greater chance of dying in mass shootings if they're at school or place of business

According to FBI data from 2013, incidents in schools and businesses represent 7 out of 10 active shootings. Some of the country's most high-profile mass shootings have occurred in those kinds of places: Sandy Hook,
