From a territorial approach, political participation is analyzed within the framework of the unprecedented Chilean constituent process (2019-2021), according to the prevalence of multidimensional poverty and area (urban, rural, mixed), at a community scale and considering three modes of participation: protests, cabildos and voting in constitutional elections. Using logistic and linear regression models with weighted least squares, the results indicate that, in general, political participation had socioeconomic and territorial biases (in upper-middle income sectors and in urban areas, participation was higher). Such inequality of political voice must be considered in the understanding of the frustrated constituent process and represents a wake-up call for democracy.
