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).
