The purpose of this erratum is to address an error in Making Young Voters: The Impact of Preregistration on Youth Turnout. The error affects the size of the coefficient estimate on preregistration laws in the difference-in-difference model reported in Table 2 (column 1). Updating the difference-in-difference model estimate finds a smaller, but still positive effect of preregistration laws on youth turnout. Taken together with the results from other model specifications, data sources, and analytic approaches, the conclusion of the article remains the same: preregistration appears to be a viable electoral policy for increasing youth turnout. The error in the difference-in-difference model comes from including state fixed effects, year fixed effects, and state*year fixed effects. Because our treatment variable—preregistration availability in the state and year—is defined by state and year, we should not include the interactions in the model. Stata version 11.2 (using code posted on the AJPS Dataverse) estimated the model by dropping the fixed effect on Delaware in 2012, resulting in a misinterpretation of the treatment variable. We are grateful to Ryan Enos, James Snyder, and the Harvard American Politics Summer Reading Group for alerting us to this error (email dated August 10, 2016) and to Anthony Fowler for following up with additional information (email dated November 22, 2016).
