Replication Data for: At-Large Elections and Minority Representation in Local Government

Despite a long history of legal challenges alleging that elections conducted at-large suppress minority representation, this remains the dominant electoral system in local governments throughout the United States. Moreover, a large empirical literature remains divided over the present-day impact of at-large elections on the political success of underrepresented groups. We reconcile the competing findings in this literature by providing contingent, causal estimates of the effect of conversion from at-large to ward elections on minority officeholding, using a novel identification strategy afforded by the California Voting Rights Act of 2001. We find a dramatic positive effect of conversion in districts where Latinos constitute a sufficiently large share of the voting population, and in large and residentially segregated districts. When these conditions are not satisfied, we consistently see null estimated effects.
