What is the Group Threat Index (GTI)?

The GTI examines the volume of terrorist and rebel alerts, messaging traffic, videos, photos, incidents and the number killed and injured by a group over the past 30 days and runs it through an algorithm to assign the group its GTI. The higher the GTI the greater the risk posed by the group. The GTI should never be the sole measure of threat posed by a group but rather one factor to take into consideration. The Global GTI is arrived at by adding up each individual group's GTI. It serves as an overall indicator of global terrorist and rebel activity. The GTI Average is the average GTI for all groups with a GTI greater then zero. The Highest and Lowest GTI's reflect the highest and lowest GTIs for any one group in this report. All individual data points used to arrive at the GTI score are available in the ICD.
