This article examines the extent to which political socialization accounts for generational differences in electoral participation found in recent studies. Political socialization is defined as the learning process in which an individual adopts various political attitudes, values and patterns of actions from his or her environment. The analysis is based on the Finnish National Elections Study 2003. The results show that even though politics has had the smallest role during the formative years of the youngest generation and they most often do not know their parents’ partisanship, this generation has received the most encouragement for voting and the attitudinal change towards voting within an individual's life span has been the most positive. Consequently, the study shows that if there were no differences in the socialization between the youngest and the older generations, the difference in turnout would be larger if only sex and socioeconomic factors were taken into account. Based on these results, the author draws the conclusion that, rather than political socialization, the factors behind the low turnout among the young generation have to be searched for elsewhere.
