The GTTAC Data Portal helps users identify, analyze, and visualize national, regional, and global terrorism incidents. Users can examine the distribution and variation in the number of incidents, deaths, and injuries by month and year over time. The online tool breaks down the frequency of terrorist incidents on critical variables. With the filter tool, users can explore the data on perpetrators, tactics, facilities, and weapons used during the attack in greater detail. Users can compare countries and terrorist groups in terms of temporal, spatial, and incident-level attributes of terrorist incidents and create visualization outputs.
