Political discontent, frequently mirrored in voting patterns, extends beyond ballot votes. By focusing on Valparaiso, Chile, we introduce a more comprehensive measure, external political efficacy (EPE), capturing a sense of abandonment and gauging public sentiment towards the political system’s responsiveness to their needs. Our analysis addresses individual and area-level factors underpinning individual variations in EPE. The evidence suggests that long-term territorial socio-economic disadvantage, rather than low-paid employment, is significantly related to individual discontent, highlighting lowered beliefs in system responsiveness.
