Political participation is often studied through socioeconomic and demographic factors such as income, education, race and ethnicity, age, housing, and poverty. Far less attention has been given to how the built environment shapes civic engagement, particularly within working-class Latina/o communities along the U.S.-Mexico border. Existing research has shown that neighborhood conditions and vehicle dependence can influence political participation, yet important questions remain about how multimodal transportation options, including walking, cycling, and public transit, as well as shared public and green spaces, affect voter turnout and civic connectedness. Drawing on Henri Lefebvre’s concept of the “production of space,” this study examines how physical infrastructure and public space may shape participation in historically underserved and underrepresented minority-majority communities. After accounting for socioeconomic conditions, neighborhood characteristics, and car dependency, the analysis investigates whether investments in transportation accessibility and shared community spaces are associated with increased voter participation. Findings may contribute to broader conversations about urban planning, social connectedness, and democratic engagement in border communities.
