Research about the determinants of electoral participation mainly relies on survey respondents self-reported voting. However, studies with individual-level validation data from the USA (Presser & Traugott, 1992), from Sweden (Granberg & Holmberg, 1991) and the UK (Swaddle & Heath, 1989) have shown strong response bias, practically only in the direction that respondents answer to have voted when in fact they have not. This leads to a systematic overestimation of electoral turnout, and has been shown to bias results about the determinants of political participation as well (Bernstein, Chadha, & Montjoy, 2001; Cassel, 2003). It is firstly prohibitively costly for political participation research, and often impossible because of data-protection laws, to solely rely on data that have been validated in voting registers. Secondly, validation data have been shown to be prone to a considerable degree of error as well. For example, in a revalidation
