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.

Key Findings

• • 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 
• • Terrorism 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.
