This paper presents the data collected in the survey Marcha das Margaridas 2019: food, social mobilization and gender, whose objective was to understand the social composition and the perception of activists on these issues. The survey was conducted on August 13 and 14, 2019 in face-to-face (458) and self-administered form (1657) modalities. The Marcha das Margaridas is one of the case studies of the Food for Justice Research Group, which analyzes social mobilizations that counter injustices in food systems, as well as social and political innovations that confront multiple and intersectional inequalities such as class, gender, race, ethnicity and nationality, in the construction of just and ecological food systems.
