This dataset comes from an online survey conducted in June 2024 with a stratified national sample of 3,000 adults in Spain. The sample reflects the country’s demographic composition in terms of gender, age, education, municipality size, and regional distribution, and was collected through the Netquest online panel. The questionnaire covered six thematic areas: (1) leisure activities and cultural preferences, including music, sports, food, and clothing; (2) mobility and transportation habits; (3) personal and relational values, such as love, sexuality, and online dating; (4) moral and political attitudes toward equality, redistribution, the environment, immigration, and gender; (5) political orientation, voting intention, and affective polarization; and (6) demographic and socioeconomic characteristics. The dataset offers a comprehensive resource for analyzing cultural practices, lifestyles, values, and political attitudes in contemporary Spain.
