GATE Data Project

The Government Actions in Terror Environments (GATE) data project is a multi-institutional effort to collect and code data on state action toward terrorist organizations or their constituencies in select countries. To date, the GATE database is the most comprehensive source of information on how governments respond on a day-to-day basis to terrorist violence.

This data can be used to identify how different types of government actions affect terrorist violence, why governments undertake certain actions, and a variety of other questions.

Initially intending to collect data solely on counterterrorism policies, Korbel Professor Erica Chenoweth and University of Maryland Professor Laura Dugan widened the scope of the data collection process to include all government actions aimed at constituent populations from which terrorist groups emerge.

The pilot project on Israel was completed in 2012, with data from 1987-2004.

The GATE-Canada data, with coverage from 1985-2013, was completed in 2015. 

At the Sié Center, project staff will continue to complete more countries' datasets for analysis, future countries to be completed are:

  • Algeria
  • Egypt
  • Turkey
  • Lebanon
  • Pakistan
  • Afghanistan
  • Philippines
  • India
  • Sri Lanka
  • United Kingdom
  • United States

Student researchers at the University of Denver support the collection, coding, and cleaning of the data for all additional countries. The project is estimated to be completed by 2015.

Project Partners

The GATE project is supported by a grant from the University of Maryland's START Consortium, part of the collection of Centers of Excellence supported by the U.S. Department of Homeland Security. The Government of Canada, through its Kanishka Project, also funds and supports the GATE Data Project.
