1. Some preliminary remarks

First a general remark about terrorism statistics: defining what counts as a terrorist attack or a terrorist fatality is controversial. According to a famous saying, one man’s terrorist is another man’s freedom fighter. Some terrorism databases or indices count rebel attacks, others don’t, some limit terrorism to peacetime, others include wartime attacks, and so on. However, a reasonably uncontroversial definition states that a terrorist attack is “an unlawful use of force and violence against persons or property to intimidate or coerce a government, the civilian population, or any segment thereof, in furtherance of political or social objectives.” The victims are usually innocent bystanders; the perpetrators are non-governmental groups; and the purpose is fear. Hence, the murder of abortion doctors would also count.

Another remark: media attention for terrorism doesn’t correspond to the importance of terrorism. There isn’t really a lot of terrorism in the world. As a cause of death, it’s ridiculously rare: in 2012, more Americans died crushed by their TVs or furniture (16) than from terrorism (10). And it was about the same in earlier years (with the exception of 2001).

causes of death


Since 9/11, 53 people have been killed by terrorists in the UK. Every one of those deaths is tragic. So is every one of the 26,805 deaths to have occurred on Britain’s roads between 2002 and 2012 inclusive, an average of 6.67 deaths a day. … This means that 12 years of terrorism has killed as many people in the UK as eight days on our roads. (source)

Which doesn’t mean we should neglect the very real suffering that terrorism causes, but this does put things in perspective.

2. US terrorism deaths

Given these caveats, here are some numbers. In the US alone – hardly the most affected country – there have been 2,608 terrorist attacks – 226 of them with fatalities – between 1970 and 2011; 9-11 of course being the deadliest one.

The severity rather than the frequency of attacks is a better measure: one attack killing nearly 3000 people is arguably worse than 3000 attacks killing hardly anyone. Here’s an indication of recent fatalities:

3. Global terrorism deaths

If we look at the rest of the world, one of the best sources for statistics on terrorism is the Global Terrorism Database:

deaths due to terrorism

global terrorism deaths


Another useful source is the National Counterterrorism Center:

countries with most deaths caused by terrorists


And then there’s also the Global Terrorism Index established by the Institute for Economics and Peace (IEP). Of the 158 countries covered by the index, only 31 have had no attacks in the ten years to 2011. However, the majority of attacks are

concentrated in just a handful of countries. Iraq ranks first based on a five-year weighted average of the number of incidents, deaths, injuries and estimated property damage. It has suffered from the most attacks, including 11 of the world’s worst 20. Indeed, Iraqis comprised one third of deaths from terrorism between 2002 and 2011. But while the number of incidents there have climbed since 2007, deaths have actually declined. Other terrorist hotspots include Pakistan, Afghanistan and India. The worst attack over the period was in Nepal, where 518 people died and 216 were injured. If there is any small cause for comfort, it is that terrorist incidents have plateaued since their peak in 2008. (source)

(This attack in Nepal, however, was an attack by Maoist rebels on a Nepalese army barracks in 2004. The vast majority of the 518 fatalities in that attack were the rebels themselves).

global terrorism index

According to the GTI, Iraq and Afghanistan account for 35% of last decade’s terrorist attacks.

8. Public opinion on the justifiability of terrorism

public opinion on targeting civilians, by religion


Those data are for US citizens only, but the data below show that Muslims in general, and not just Muslim Americans, aren’t more inclined to accept terrorism:

9. Terrorism and form of government

Interestingly, terrorism tends to occur much more in democratic countries than in nondemocratic ones:

10. Counter-terrorist actions

Counter-terrorist actions also produce fatalities. Perhaps the most salient form of counter-terrorism are drone attacks. Since 2004, drone strikes have killed an estimated 3,110 people in Pakistan. Less than 2% of those have been high-profile targets. Many have been innocent bystanders (source). Torture is another problem. Some data here.

  1. I was hoping to see charts that show terrorism by type of religion – for example, the yearly frequency of attacks by members of Islam, Christians, Hindus, Atheists, etc – correlated by percentage of world population.

  2. Lala says

    “All Terrorists are Muslims…Except the 99.6% that aren’t”, try this link…it can be a very instructive article!

  3. Cassandra says

    Thank you for the statistics. I use some of the information for my project. Please send me an email if you have more information.

  4. maria says

    you should have a posting of stats based on female terrorism, and the increase for the past three decades now.

  5. this is really good research, I’m a senior here at new tech high school in Anderson, CA and this is really extraordinary. Thank you for you statistics!! helped A lot!!

  6. roondog says

    I read “” awhile back, and loved it. and I was able to find terror attack by religion, from the link they provided, which was to the FBI’s website, but it has since vanished. I think the only thing on the FBI’s site now is by year, and they are only recent years. it’s frustrating.

  8. Hey there,

    I’ve enoyed your coverage of terrorism and how it has developed after the death of Bin Laden. I recently finished working on an infographic that explores this issue and other interesting information about Al Qaeda from a visual perspective. I thought I would share it with you in the hopes you might make some use of it. Here’s the link:

    It seems odd that the country of Israel does not appear to be listed on any of these lists or charts. I seem to recall that they have had a pretty serious history with Palestinian terrorist groups.

  14. David T says

    By the same logic, it’s safer to climb Mt Everest than to drive to work.

  15. David T says

    Terrorism statistics should not be compared to accidents and incurable diseases as terrorism is a deliberate act. It is murder of people, men, women and children going about their daily lives. The acceptable number of terrorism deaths or injuries is zero.

    The number of terrorism acts is a poor statistic, and obviously requires the definition of what is an act of terrorism. For example the FBI list of terrorism acts 2002-2005 includes 9/11 and on 9/16/2005 an act of attempted arson by the animal liberation front. Clearly these 2 acts do not deserve equal weighting and is why counting acts is misleading. It is a secondary statistic for guiding law enforcement, but some people misleadingly promote it as THE statistic. Injuries and fatalities are the meaningful statistics.

    When terrorist acts are committed, it will always be traced back to a group or race. What is needed is those groups to vocally denounce the acts, as silence will always be interpreted as tacit approval. Loud and clear denouncement is needed.

  16. Ian says

    Note by limiting perpetrators to non-governmental groups, acts of terrorism such as the bombing of Pan-Am flight 103 over Lockerbie in Scotland and killing of 6 million Jews in the Holocaust are not counted in these statistics as both were acts of terrorism by governments. If terrorism by governments were counted in these statistics then the deaths caused by non-governmental terrorists would be swamped and difficult to spot.
