What is the Global Terrorism Index?
The Global Terrorism Index (GTI) is a comprehensive study analysing the impact of terrorism for 163 countries covering 99.7 per cent of the world’s population.
The GTI report is produced by the
Institute for Economics & Peace
(IEP) using data from Terrorism Tracker and other sources. The
GTI methodology
produces a composite score so as to provide an ordinal ranking of countries on the impact of terrorism. The GTI scores each country on a scale from 0 to 10; where 0 represents no impact from terrorism and 10 represents the highest measurable impact of terrorism.
Given the significant resources committed to counter-terrorism by governments across the world, it is important to analyse and aggregate the available data to better understand its various properties. One of the key aims of the GTI is to examine these trends. It also aims to help inform a positive, practical debate about the future of terrorism and the required policy responses.

Global Terrorism Index 2026
Key findings from the Global Terrorism Index 2026 report
Deaths
from terrorism fell by 28 per cent to 5,582, and incidents decreased by 22 per cent to 2,944, marking the lowest figures since 2007
In contrast, Western
terrorism fatalities rose sharply by 280 per cent to 57 in 2025, largely driven by antisemitism, Islamophobia and political terrorism
Iran risks becoming another breeding ground for terrorist militias if it becomes a failed State
Six of the ten countries most impacted by terrorism are in sub-Saharan Africa, maintaining its position as the epicentre
For the first time,
Pakistan leads the Index as the country most impacted by terrorism
, experiencing a sharp resurgence with 1,139 deaths and 1,045 incidents in2025, its highest level since 2013
Youth radicalisation fuelled lone-wolf attacks
, with youth terrorism investigations rising threefold since 2021. Over the same period, 93 per cent of all fatal attacks in the West were lone-wolf attacks
Islamic State (IS) and its affiliates remained the
deadliest terrorist organisation in 2026
, responsible for just under 17 per cent of all attacks worldwide
errorism in borderlands has more than doubled over the past 15 years. Over 76 per cent of attacks occurred within 100 km of an international border in 2025, up from just under 60 per cent in 2007.
Escalation of the conflict in Iran
could further destabilise the MENA region and increase the risk of groups sympathetic to Iran carrying out terrorist attacks overseas.
