Political and Affective Polarisation in a Democracy in Crisis: The E-Dem Panel Survey Dataset (Spain, 2018-2019)

The E-DEM dataset is a micro-level online panel survey of the Spanish voting age population comprised of four waves carried out over a six-month period between late October 2018 and May 2019 (the detailed timing of each wave will be presented in Table 1). The survey waves coincide with key moments in Spanish political life (including local, regional, national, and European elections, as well as the conviction of Catalan secessionist leaders). It also covers the six-month period of the surge of Spain’s new radical right party, Vox, spanning from shortly before its first major electoral success in Spain’s most populate region, Andalusia, to its consolidation in the May 2019 European elections. In addition, the project comprises a series of survey experiments, embedded in the different waves, regarding measures on confidence in institutions, exposure to media and social networks, as well as on political behavior and polarization attitudes based on passive data, captured with software that the interviewees installed on their mobile devices. Three datasets are provided: the four-waves dataset, the experimental dataset, and the integrated dataset, which includes the former two. Each dataset is provided in three formats: tab-separated delimited text, tab-separated rawtext, and Stata 15.0 (.dta).E-DEM数据集是针对西班牙适龄投票人群的微观级在线面板追踪调查，于2018年10月下旬至2019年5月间的六个月周期内开展了四轮调查（各轮次的具体时间安排详见表1）。该调查各轮次的开展时点与西班牙政治生活中的一系列关键节点高度契合，涵盖地方、大区、全国及欧洲议会选举，以及加泰罗尼亚分离主义领导人的定罪审判。本数据集同时覆盖了西班牙新兴激进右翼政党Vox崛起的六个月周期，时间跨度从该党在西班牙人口最多的大区安达卢西亚取得首次重大选举胜利前不久，直至其在2019年5月欧洲议会选举中站稳脚跟。 此外，本项目在各轮次调查中嵌入了一系列调查实验，实验内容涉及公共机构信任度、媒体与社交网络接触情况，以及基于被动数据的政治行为与极化态度研究——该被动数据由受访者安装在其移动设备上的专用软件采集获取。 本次共提供三类数据集：四轮追踪调查数据集、实验数据集，以及整合前两类数据的综合数据集。 每类数据集均提供三种格式：制表符分隔定界文本文件、制表符分隔原始文本文件，以及Stata 15.0格式（.dta文件）。
