Political participation is a prerequisite for democracy. Therefore, political sociologists have advised to socialize people by encouraging political participation from a young age onward. Parents are one of the most important political socialization agents, especially at a young age. Although the intergenerational transmission of political attitudes has been studied quite intensively, the transmission of the political participation intention has been neglected. This study explores the effect of both mothers' and fathers' political activity on their offspring's intention to participate. Using a data set from 2085 Belgian parent-child triads, we tested the direct and indirect transmission of political participation intention. We found that although there is a direct transmission of political participation intention, after controlling for political discussion, political interest and socio-economic status, this effect is completely mediated. Therefore, we conclude that intergenerational transmission is an indirect process, supported by a high socio-economic status, more political interest and a more politicized family environment in which politics is clearly perceived as salient.
