Country Reports on Terrorism 2013: Annex of Statistical Information

Title 22, Section 2656f of the United States Code requires the Department of State to include in its annual report on terrorism "to the extent practicable, complete statistical information on the number of individuals, including United States citizens and dual nationals, killed, injured, or kidnapped by each terrorist group during the preceding calendar year." The definition found in Title 22 of the US Code provides that terrorism is “premeditated, politically motivated violence perpetrated against noncombatant targets by subnational groups or clandestine agents.”

This Annex of Statistical Information is a guide to worldwide terrorist activity as reported by unclassified sources. We hope that these data will be useful for improving knowledge about patterns and characteristics of terrorism, and helpful for maintaining global awareness of the threat it poses.

The Annex of Statistical Information is provided for statistical purposes only. The statistical information contained in the Annex is based on reports from a variety of open sources that may be of varying credibility. Nothing in this report should be construed as a determination that individuals associated with the underlying incidents are guilty of terrorism or any other criminal offense. As with all records in the Global Terrorism Database, the information may be modified, as necessary and appropriate, if new information becomes available.

Any assessments and descriptions, including those regarding the nature of the incidents or the factual circumstances thereof, are offered only as part of the analytic work product of the National Consortium for the Study of Terrorism and Responses to Terrorism (START) and may not reflect the views of the United States Government.
