ITERATE, International terrorism: attributes of terrorist events, 1960-2020

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 data are available in two formats: as MS Excel tables and as text-file narratives. The Excel Tables are available for download via this Dataverse record. For access to the text-file narratives, please contact the Map & Data Library, University of Toronto. ITERATE’s numeric version, in Excel format, covers 1968 through 2020, coding the incidents discussed in the textual chronologies. It combines four distinct and interrelated files which count the most salient components of international terrorism: Common File 1968-2019 - includes over 13,000 cases and 42 variables Hostage File 1968-2007 - coded characteristics of 1,410 terrorism incidents that involved hostage-taking, with 41 variables Fate File 1968-1987 - includes 974 incidents and14 variable Skyjack File 1968-1987 - includes over 372 skyjacking incidents and 27 variables All variables and values for the data have remained consistent. New values are added with the emergence of new terrorist groups and types of terrorist activity. Incident codes for each event are consistent across files, enabling immediate cross reference. See codebook for further information. The datasets are based upon, inter alia, an exhaustive search of major media, research, news and information services, including AP, UPI, Reuters, CNN , MSNB , AFP, The Washington Post, New York Times, LA Times, Time, Newsweek, and al-Jazeera. The chronology incorporates information obtained from interviews with government officials, scholars, and former hostages/others involved in international terrorist incidents. Additional sources include relevant manuscripts and scholarly publications dealing with the subject. Finally, the chronology uses many official government chronologies, including those published by the NCTC, FBI, CIA, US Department of State, and FAA. ITERATE Text and ITERATE Numeric data files were acquired in April 2021.

ITERATE项目（ITERATE Project）旨在量化统计跨国恐怖组织的特征、具有国际影响力的恐怖活动及其运营环境相关数据。该项目的数据包含两种格式：Microsoft Excel（MS Excel）表格与文本叙事文件。Excel格式的表格数据集可通过本数据verse（Dataverse）记录下载；如需获取文本叙事文件，请联系多伦多大学地图与数据图书馆（Map & Data Library, University of Toronto）。

该项目的Excel数值版数据集覆盖1968年至2020年，对时序年表中记载的恐怖事件进行编码。该数据集整合了4个相互独立且彼此关联的文件，用于统计国际恐怖主义最显著的构成要素：
1. 1968-2019年通用文件：包含逾13000起事件与42个变量；
2. 1968-2007年人质事件文件：对1410起涉及人质劫持的恐怖事件特征进行编码，共包含41个变量；
3. 1968-1987年结果文件：包含974起事件与14个变量；
4. 1968-1987年劫机文件：包含逾372起劫机事件与27个变量。

所有数据的变量与变量值均保持统一标准。随着新型恐怖组织与恐怖活动类型的出现，数据集会同步新增对应数值。各事件的事件编码在所有文件中保持一致，可直接进行跨文件交叉参照。详细信息请参阅编码手册（codebook）。

本数据集除其他来源外，基于对主流媒体、研究机构、新闻与信息服务机构的穷尽式检索，信息来源包括美联社（AP）、合众国际社（UPI）、路透社（Reuters）、美国有线电视新闻网（CNN）、微软全国广播公司（MSNBC，原文标注为MSNB）、法新社（AFP）、《华盛顿邮报》《纽约时报》《洛杉矶时报》《时代》周刊、《新闻周刊》以及半岛电视台（al-Jazeera）。

该时序年表整合了通过采访政府官员、学者、前人质及其他涉及国际恐怖事件的相关人员所获取的信息。其他补充来源包括与该主题相关的手稿及学术出版物。此外，该年表还参考了诸多官方政府发布的年表，包括美国国家反恐中心（NCTC）、联邦调查局（FBI）、中央情报局（CIA）、美国国务院以及美国联邦航空管理局（FAA）的官方年表。

ITERATE文本数据集与数值数据集文件于2021年4月完成获取。
