It aggregates the most authoritative data source on terrorism today, the Global Terrorism Database (GTD) collated by the National Consortium for the Study of Terrorism and Responses to Terrorism (START) into a composite score in order to provide an ordinal ranking of nations on the negative impact of terrorism. The GTD is unique in that it consists of systematically and comprehensively coded data on domestic as well as international terrorist incidents and now includes more than 140,000 cases.
The 2015 Global Terrorism Index highlights that terrorism continues to rise. The total number of deaths from terrorism in 2014 reached 32,685, constituting an 80 per cent increase from 18,111 the previous year. This is the highest level ever recorded. The significant majority of these deaths, over 78 per cent, occurred in just five countries; Iraq, Nigeria, Afghanistan, Pakistan and Syria.
While terrorism is highly concentrated in a small number of countries, the number of countries which have had a terrorist attack is also increasing. In 2014 terrorism impacted more countries than ever before. Attacks were recorded in 93 countries, up from 88 in 2013. This continues the trend from 2011 with more countries experiencing terrorist attacks and deaths each year.
Furthermore, there was a 120 per cent increase in the number of countries that recorded over 500 deaths: in 2014 eleven countries, up from five countries in 2013. Nigeria experienced the biggest year-on-year increase in deaths ever recorded with 5,662 more people being killed, an over 300 per cent increase.
