Political Generations and Electoral Change in Canada

Richard Johnston*

Abstract

This article lays out the elementary logic of age structures in party preference data and proposes a simple estimation model with demographic and historical elements. As voters age their preferences intensify. But they do not intensify much and generational differences in the direction of party preferences are correspondingly weak. The Canadian electorate does not seem all that strongly anchored by the accumulated experience of the individuals that make it up. The major source of long-term electoral change, therefore, is conversion in the existing electorate. Consideration is given to how distinctive the Canadian pattern is.
