Mass Shootings by Country 2021

Very few topics of discussion can evoke a more passionate (or politically charged) emotional reaction than the subject of mass shootings.

The main reason for this volatility is that most everyone agrees that mass shootings are horrific, but—particularly in the United States—virtually no one seems to agree on what causes mass shootings or what needs to be done about them.

One primary reason for this disconnect is that reliable data on mass shootings can be notoriously, frustratingly difficult to obtain.

How Differing Definitions of "Mass Shooting" Confound Comparisons

The first complication is that there is no official, universally accepted definition for a mass shooting, so each stat-tracking organization has its own qualifying criteria. As such, database-to-database differences are common—and confounding.

For example, the United States Federal Bureau of Investigations (FBI) defines a mass shooting as a single attack that happens in a public place and in which three or more people are killed with a firearm. However, most other stat trackers require at least four fatalities.

Similarly, some databases include events in which at least four people were wounded, but not necessarily killed. Others do not. Some databases include occurrences in which the shooter killed only family members (but still in a public place, such as a restaurant). Others do not. Some databases include organized terrorist attacks, armed robberies gone wrong, and gang-related shootings. Other databases discard some or all of these incidents.

In fact, in a 2019 study that compared four different databases, the number of mass shooting events recorded in the U.S. for the year 2017 ranged from a low of 11 to a high of 346.

Clearly, a significant error margin exists, particularly when creating country-to-country comparisons.

Statistics related to the overall level of gun violence in a given country tend to be easier to obtain. However, few gun-related deaths fall under any definition of a mass shooting.

In fact, in the U.S., roughly two-thirds of all gun-related deaths are suicides. In 2016, for example, there were 37,353 gun deaths in the United States. Of these, 22,938 were suicides, and 14,415 were homicides. Within the homicides, 71 were a result of a mass shooting.

Mass Shootings: A Global Concern

Although events in the U.S. tend to get the lion's share of media exposure, mass shootings are clearly a worldwide issue. Below is an alphabetized list of just some of the developed countries other than the United States that have experienced one or more mass shootings in the past few decades.

  • Azerbaijan
  • Belgium
  • Bosnia and Herzegovina
  • Brazil
  • Finland
  • France
  • Germany
  • India
  • Israel
  • Italy
  • Nigeria
  • Norway
  • Philippines
  • Russia
  • Serbia
  • Spain
  • Switzerland

The United States does have an unusually high rate of gun violence for a developed and wealthy nation. Viewed in terms of sheer volume, the U.S. also tallies the most mass shootings](/state-rankings/mass-shootings-by-state), with (depending upon definition) somewhere between 21 and more than 600 in 2020.

Does the United States have more mass shootings than other countries? It depends on the data

Exactly how mass shootings in the U.S. compare to those in other countries is a highly disputed subject.

In a widely publicized study originally released in 2015, the pro-gun nonprofit Crime Prevention Research Center (CPRC) compared the annual number of mass shooting deaths per million people in the U.S. to that of Canada and several European countries from 2009 to 2015. The result? Norway led the world with 1.88 deaths per million, followed by Serbia, France, and Macedonia. Where did the U.S. rank? 11th place.

Average (Mean) Annual Death Rate per Million People from Mass Public Shootings (U.S., Canada, and Europe, 2009-2015):

  1. Norway — 1.888
  2. Serbia — 0.381
  3. France — 0.347
  4. Macedonia — 0.337
  5. Albania — 0.206
  6. Slovakia — 0.185
  7. Switzerland — 0.142
  8. Finland — 0.132
  9. Belgium — 0.128
  10. Czech Republic — 0.123
  11. United States — 0.089
  12. Austria — 0.068
  13. Netherlands — 0.051
  14. Canada — 0.032
  15. England — 0.027
  16. Germany — 0.023
  17. Russia — 0.012
  18. Italy — 0.009

In addition, a 2018 CRPC study ranked the U.S. at number sixty-four in the world in terms of mass shooting rates per capita.

Statistics under scrutiny: Why some experts disagree with the CRPC report on mass shooters

As eye-opening as the CRPC study was, many statisticians believe the reason the results seem so counterintuitive is that they’re incorrect.

One of the more detailed analyses appeared on the fact-checking website and concluded that the CRPC report used “inappropriate statistical methods” which led to misleading results.

According to the snopes analysis, one of those inappropriate methods was the leaving out of the many European countries that had not experienced a single mass shooting between 2009-2015. This data would not have changed the position of the U.S. on the list, but its absence could lead a reader to believe—incorrectly—that the U.S. experienced fewer mass shooting fatalities per capita than all but a handful of countries in Europe.

A more important oversight, again according to snopes, was the report's use of average deaths per capita instead of a more stable metric. Thanks to the smaller populations of most European countries, individual events in those countries had statistically oversized influence and warped the results.

For example, Norway’s world-leading annual rate was due to a single devastating 2011 event, in which far-right extremist Anders Behring Breivik gunned down 69 people at a summer camp on the island of Utøya. Norway had zero mass shootings in 2009, 2010, 2012, 2013, 2014, and 2015.

An easy—though arguably insensitive—way to illustrate the shortcomings of this approach is to imagine it applied to the 9/11 attacks, which killed 2,977 people in the United States on a single day in 2001. Running that data through the CRPC formula yields the following statistic: Plane hijackings by terrorists caused an average of 297.7 deaths per year in the U.S. from 2001-2010. This is, in fact, mathematically accurate—but it paints a badly distorted picture of what actually happened during those ten years.

In addition, the CRPC study went a step further and computed average annual deaths per capita. Critics argue this further warps the data, because Norway’s population is a fraction of the U.S. population. As a result, Norway’s death rate came out more than 20 times higher than that of the U.S.—which tallied 66 deaths in 2012 alone (nearly matching Norway's total for the full study) and averaged at least one death per month for the entire seven-year data set.

A possible better alternative to the CPRC mass shooter report

The snopes analysis goes on to suggest that instead of computing the average, or mean mass shooting deaths, a better method would be to compute the median, or typical, number of deaths. The median is considered by many statisticians to be better at preventing individual outlier events (such as the Norway massacre) from skewing results, which leads to a more accurate day-to-day impression and country-to-country comparison.

Using the CPRC’s own data and more precise per-year population data from World Bank (the original study used only 2015 population data) to solve for the median, the snopes analysis results in a notably different list:

Typical (Median) Annual Death Rate per Million People from Mass Public Shootings (U.S., Canada, and Europe, 2009-2015):

  1. United States — 0.058
  2. Albania — 0
  3. Austria — 0
  4. Belgium — 0
  5. Czech Republic — 0
  6. Finland — 0
  7. France — 0
  8. Germany — 0
  9. Italy — 0
  10. Macedonia — 0
  11. Netherlands — 0
  12. Norway — 0
  13. Russia — 0
  14. Serbia — 0
  15. Slovakia — 0
  16. Switzerland — 0
  17. United Kingdom — 0

Using the median analysis, the United States is the only country examined that shows a propensity for mass shootings. The data itself supports this interpretation, as the United States endured mass shooting events all seven years, but the other countries all experienced mass shootings during only one or two years. Thus, in a typical year, most countries experience zero mass shooting deaths, while the US experiences at least a few.

Additional reports on mass shootings in the United States and the world

Many other studies and articles also offer opinions or interpretations counter to that of the CPRC.

For example:

A 2019 paper from Econ Journal Watch, a scholarly economics journal, notes that the CPRC data included many events that would be considered military or terrorist actions, such as when 200 insurgents in Ethiopia attacked an oil field and shot 74 people. While these are undeniably tragic deaths, the EJW proposes that they are not what most people associate with the term "mass shooting" and should not be included.

A 2021 BBC article used data from the FBI and the Las Vegas Police to point out that eight of the ten deadliest mass shootings in the past 20 years in the United States occurred between 2001 and 2021 (implying that mass shootings are becoming more frequent).

A 2016 paper from the University of Alabama compared 171 countries from 1966 to 2012 and concluded that the United States accounted for only 5% of the world’s population, but 31% of its mass shootings. CPRC has questioned the legitimacy of this report's data.

A 2015 Politifact article criticizing then-President Barack Obama’s statement that no other advanced country has mass shootings like the U.S. cited data from 2000 to 2014 to prove that mass shootings do indeed happen in other advanced countries. However, the article conceded that the [U.S. experienced 133 shootings] ( during that period, while the next-highest total was Germany with 6.
