Limited supply: Youth underrepresentation in the Canadian House of Commons

Much of the research on youth representation focuses on the final stage of electoral recruitment: young peoples' presence in legislatures. We expand this scope using a supply and demand framework to document the representation of young people not only in parliament but also in the candidate stage that proceeds it. Drawing on an extensive dataset of more than 3000 candidates in Canadian federal elections from 2008 to 2021, we show that young peoples’ numerical underrepresentation is not primarily a function of voter discrimination but rather a result of the small number of young candidates who come forward. We find that limited youth representation in the candidate pool translates into low representation rates in parliament. These results suggest that efforts to ameliorate youth underrepresentation in politics must be attentive to supply-side issues, including party gatekeeping, resource constraints, political ambition, and the motivations for running for office.
