This paper introduces transnational terrorist hostage event (TTHE) data set from 1978 to 2018. TTHE includes up to 50 variables for each of its 1,974 incidents, based on information in media sources. Four types of hostage incidents—kidnappings, barricade missions, skyjackings, and non-aerial hijackings—are recorded for a global sample. Select key variables include the number of hostages, targets of abductors’ demands, terrorist behavior in negotiations, amount of money ransom demands, other kinds of demands, duration of incident, and the outcome of negotiations. Our hostage data set also indicates location start and end, attack force size, victim numbers, casualties, weapons used, and logistical outcome. TTHE is tied to the International Terrorism: Attributes of Terrorist Events (ITERATE). We display interesting features of hostage incidents over time and an application of TTHE to identify the determinants of logistical and negotiation successes for hostage missions.

本文介绍了从1978年到2018年的跨国恐怖分子人质事件（TTHE）数据集。根据媒体来源的信息，TTHE对其1,974起事件中的每一个都包含多达50个变量。记录了四种类型的人质事件，包括绑架，路障任务，空中劫持和非空中劫持。选择的关键变量包括人质数量，绑架者要求的目标，谈判中的恐怖行为，金钱赎金要求，其他种类的要求，事件的持续时间以及谈判的结果。我们的人质数据集还指示了地点的起点和终点，攻击力量的大小，受害者人数，伤亡人数，使用的武器和后勤结果。这与《国际恐怖主义：恐怖主义事件的属性》（ITERATE）相关。
