In this paper, we explore the roots of perceptions of local corruption in U.S. cities, using survey data collected from 39 cities during 40 different mayoral election campaigns. We examine the impact of the city-level corruption context alongside measures of political information, partisan and racial/ethnic representation in local government, evaluations of personal and policy satisfaction, and other individual-level attitudinal and demographic characteristics. We find that perceptions of local corruption are responsive to the local corruption context—though this relationship is heavily conditioned by political knowledge—satisfaction with local conditions, other attitudinal measures, and, to a lesser extent, co-ethnic representation in local government.
