The state of terrorism in wealthy countries, explained with numbers

In 2016, OECD member countries experienced the most deaths from terrorism since the September 11 attacks in 2001. According to the Global Terrorism Index released in November, there has been a 67% increase in attacks and a nearly 600% increase in deaths from terrorism since 2014.

The report, which is produced by the Institute for Economics & Peace, shows that a significant portion of these deaths resulted from a small number of attacks that inflicted very high casualties. The November 2015 Paris attacks killed 137, the July 2016 Nice truck attack killed 87 and the June 2016 Orlando nightclub shooting resulted in 50 deaths. Combined, these three attacks account for 44% of all deaths from terrorism in OECD countries between 2014 and June 2017.

ISIL has been primarily responsible for driving this increase in deaths, with the group carrying out attacks in 18 of the 33 OECD countries since 2014. The group's ability to undertake and inspire attacks among OECD countries has been largely due to its successful exploitation of social media and the internet. ISIL has harnessed encryption technology for timely unmonitored communication between commanders in Iraq and Syria and operatives in the OECD. It has also developed a broad message that can be easily contextualised and distributed widely across various channels.

On 22 September 2014, leaders within the terrorist group issued a direct call to action for followers to carry out attacks in their home country. The imperative driving this message has since strengthened as ISIL fortunes have deteriorated on the battlefields in Iraq and Syria. With the loss of its self-declared caliphate, it has become harder for fighters to travel to the conflict zones. The group has subsequently further urged sympathisers to carry out attacks in their home countries and there has been a corresponding substantial increase in terrorism in these countries. These attacks have either been directed by ISIL or linked indirectly to them through contacts with perpetrators. Some attacks have also been inspired by ISIL but carried out by perpetrators who have had no direct contact with the organisation.

In what appears to be a positive trend, attacks attributed to the group appear to have peaked in 2016 with a notable decrease in the first six months of 2017. In 2014 there were ten attacks involving ISIL. This number increased to 31 in 2015 and seemingly peaked at 43 in 2016, with only 14 attacks in the first six months of 2017. A similar trend can be seen with attacks inspired by ISIL but not actually involving the group. The number of attacks increased from 17 in 2014 to 68 in 2016, yet declined to only 19 attacks in the first six months of 2017. This apparent decline coincides with ISIL’s diminishing capacity following its territorial losses in Iraq and Syria.

This seemingly positive trend is welcome news, although citizens understandably remain concerned about attacks within their home cities. France in particular has suffered from this rise in terrorism since 2014. Among OECD countries, France has witnessed the highest number of fatalities over the last three years and accounts for 43% of all deaths. Further, terrorist attacks related to ISIL caused 92% of the deaths in France.

Since the September 11 attacks, terrorism in the United States has remained relatively low, although the Pulse nightclub shooting in Orlando resulted in 50 deaths which pushed the total deaths from terrorism up to 64 people in 2016. However there has been a notable increase in lone actor attacks within the United States, which has suffered more lone actor attacks than any other OECD country. It experienced 32% of these types of attacks and 28 per cent of fatalities across OECD since 2008.

Greater investments in counterterrorism by OECD nations have resulted in an increased number of ISIL attacks, as well as ISIL-inspired attacks, being thwarted by the authorities. In 2016, two in three ISIL-involved attacks were foiled compared to about half of ISIL-inspired attacks.

The increasing ability of authorities to thwart ISIL terrorist attacks possibly reflects the fact that terrorism in OECD countries is certainly not without precedent. Prior to 2014 authorities had not encountered any ISIL related terrorist attacks. But terrorism in OECD member countries predates the emergence of ISIL and many nations have experienced some form of terrorism. Since 1970, there have been nearly 10,000 deaths from terrorism among OECD countries. Some 58% of these deaths occurred prior to 2000 and deaths from terrorism in 2016 were less than half of the number of deaths in 1985. Many of the deaths prior to 2000 were due to attacks by separatist groups, such as those based in Ireland and Spain.

Over 1,000 people have been killed in Spain as a result of terrorism since 1970, and the Basque Fatherland and Freedom party was responsible for around 70% of these deaths. The group also conducted attacks in France. The United Kingdom accounts for a quarter of all deaths from terrorism among OECD countries since 1970 with approximately 2,400 deaths. Most of these deaths resulted from attacks by Irish separatist groups with the Irish Republican Army responsible for every second death from terrorism in the United Kingdom.

While the recent increase in deaths from terrorism by radical Islamist extremists is substantial and is dissimilar from prior waves of terrorism that were largely driven by separatist causes, it remains important to remember that this is not the first time OECD nations have had to respond to terrorism. History also suggests that authorities have been successful in responding to the evolving threat of terrorism to safeguard their citizens.

Editorial note - This blog draws heavily on data and analysis within the 2017 Global Terrorism Index, which is published by the Institute for Economics & Peace (IEP). The analysis within this report excludes Israel and Turkey from its definition of OECD countries as IEP views the nature of the terrorist threat in these countries as not directly comparable with the other OECD member states. In Israel, the majority of terrorism is driven by broader political tension as part of the long standing Palestinian- Israel conflict. Similarly, in Turkey the majority of terrorist attacks are either from Kurdish separatists or arise from flow-on effects from the neighbouring Syrian conflict. Since 1970, Turkey and Israel combined have had over 5,000 deaths from terrorism since 2002.
