Intergenerational Representation in Electoral Systems

Summary

Intergenerational representation refers to the extent to which electoral bodies reflect the age composition of the electorate. Across democracies, legislative assemblies and executive offices are often dominated by older cohorts, creating a democratic deficit for younger and future generations. This imbalance can shape policy outcomes—favouring pensions and healthcare over education and climate action—and may discourage youth turnout, weakening political legitimacy. Key structural factors include electoral system design, candidate selection mechanisms and formal age requirements. Proportional representation systems and lower minimum age thresholds tend to enhance youth presence, while majoritarian or plurality systems often favour established, older candidates. Party dynamics—such as the strength of youth wings and decentralised nomination processes—interact with institutional rules to determine the age profile of elected officials. New datasets and indices allow systematic comparison across countries and over time, revealing persistent under-representation of those under 40 and wide regional variation. Reform proposals range from age quotas and reserved seats to mentorship schemes and targeted public funding for young candidacies. In the context of ageing populations and rapid societal change, ensuring generational pluralism in representative institutions has become a global priority both for democratic fairness and for the formulation of policies that address intergenerational equity.
