Protest in times of change. The PROTEiCA project survey.

This paper introduces the PROTEiCA project survey, a dataset designed to explore the normalization of protest participation and the societal impact of large-scale demonstrations. The survey, conducted in 2019, provides a representative sample of the Spanish population aged 18 and over, focusing on the International Women's Day protests-among the largest mobilizations in Spain's history-and their political and social significance. The dataset includes variables on protest participation, and public perceptions of recent and historical mobilizations, enabling robust analyses of contentious events and their effects. This paper outlines the construction of the dataset, detailing the questionnaire design, the cross-sectional methodology with daily tracking over 20 days, and the administration strategy. Key insights into the dataset's value and potential applications for both expert and non-expert researchers are provided, highlighting its contribution to understanding protest normalization and the dynamics of societal change. By making this innovative dataset accessible, the PROTEiCA survey aims to support and inspire future research, fostering new insights into the dynamics of social movements and collective action.
