Terrorism in Armed Conflict: New Data Attributing Terrorism to Rebel Organizations


The Terrorism in Armed Conflict (TAC) project integrates the Uppsala Conflict Data Project (UCDP) sample of rebel organizations with START’s Global Terrorism Database (GTD), covering 409 organizations 1970- 2013. Many GTD incidents are missing, or include ambiguous, perpetrator information. Because the accuracy of perpetrator information likely varies systematically, simply dropping these incidents from analyses may bias results. TAC provides possible attribution to specific rebel groups with coding for uncertainty, enabling researchers to 1) address ‘description bias’ in media-based terrorism data, 2) model uncertainty regarding perpetrator attribution, and 3) vary the way terrorism is counted.
