The Age Gap in Voter Turnout Through Time and Space.

Young adults have since long been identified as a group of the electorate least likely to vote. Recent research suggests, however, that turnout among young cohorts is declining rapidly in some countries. It does so at a much faster pace than the turnout among older age groups. In sum, today's youth turns out at lower levels than their parents or grandparents did when they were young. Consequently, the turnout gap between younger and older voters enlarges. The trend towards a widening generational divide has been particularly well documented in Canada and Great Britain. In other countries, such as Sweden and the Netherlands, the turnout difference between younger and older citizens is however stable through time. This paper contributes to the literature on youth participation by assessing the age gap in voter turnout in a longitudinal and comparative way. After observing patterns in the age gap in turnout, competing hypotheses explaining trends are put to the test. Using time-series cross-sectional analysis, the impact of both characteristics of elections and characteristics of voters on the age gap are assessed. The focus is exclusively on Western democracies for which the age gap can be estimated through election survey data. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]
