This thesis examines how subnational democratic contexts shape political self-censorship in Argentina. Using data from the 2017 World Values Survey and Gervasoni’s Subnational Democracy Index, it analyzes whether variations in provincial democratic quality are associated with citizens’ willingness to express political opinions. Self-censorship is operationalized through both direct measures of political conversation and indirect indicators based on item nonresponse to sensitive political questions. Employing multilevel regression models that account for individual- and provincial-level factors, the analysis shows that higher levels of subnational democratic quality are associated with lower levels of self-censorship. These relationships persist after controlling for political interest, civic engagement, and sociodemographic characteristics, indicating that democratic context exercises an independent effect on expressive behavior. The findings suggest that uneven democratic practices within a nationally democratic regime shape citizens’ perceptions of expressive risk, contributing to patterns of self-censorship in hybrid subnational contexts. By focusing on within-country variation, this study contributes to the literature on self-censorship by showing how subnational differences in democratic quality shape individual-level political expression within a nationally democratic regime.
