Accessing the GTD

Since 2001, START has compiled and published the GTD for use by scholars, analysts, financial modelers, journalists, security professionals, and policy makers. It has been our privilege to work closely with these user communities to continually improve the data and inform stakeholders. 

To better enable us to continue to provide the GTD for free to those who use it for scholarly research, we made the decision in 2019 to engage on a commercial basis with other users who value the GTD. To allow us to focus on the continual improvement of the data, we have partnered with a distribution partner to engage with commercial users. 

Our distribution partner CHC Global, has expertise of delivering terrorism analytics in the public and private sectors. Importantly, they share our commitment to distributing the GTD widely to those who work to understand and defeat terrorism, making them ideal partners.

User Selection

Since October 2019, the GTD is available without a fee only for individual, rather than organizational use.

Individual Use” includes scholarly, educational, research purposes, including classwork, theses, dissertations, and academic publication.

Organizational Use” includes using the data to perform services for a fee, to produce or manufacture products for sale to third parties, or to promote commercial advantage.

In order to qualify to access the GTD for free you must therefore meet the following criteria:

  •     You must be using the GTD in your personal capacity and not on behalf of an entity of any type.
  •     You must be using the GTD only for scholarly, educational, or research purposes.
  •     You must not use the GTD for commercial purposes.

United States Government users should select “Organizational Use” and fill out the brief form to request access using a .gov or .mil email address. For more information, please see the FAQ regarding USG employees and contractors.
