ITERATE : 1968-2022 : Data Codebook and Iterate Common File (y) 2021

The ITERATE project is an attempt to quantify data on the characteristics of transnational terrorist groups, their activities which have international impact, and the environment in which they operate. ITERATE 3 and 4 update the coverage of terrorist incidents first reported in ITERATE 1 and 2, which can be obtained from the Inter-University Consortium for Political and Social Research, Box 1248, Ann Arbor, Michigan 48106. ITERATE 3 and 4 are compatible with the coding categories used in its predecessors, but includes new variables.

The dataset consists of four parts. Nearly all incidents appear in the COMMON file, which the FATE, HOSTAGE and SKYJACK files supplement. Some non-terrorist domestic skyjackings appear in the SKYJACK file and not in the COMMON file. In cases in which we know what happened to the terrorists, we record their destiny in the FATE file. Variables specific to hostage-taking incidents, including aerial, land, and sea hijackings, barricade-and-hostage situations, and kidnappings are provided in the HOSTAGE file.
