The EU and established political parties are facing core demographic challenges. The proportion of seniors (i.e. those aged over 55 years) will increase from just over 18% of the population today to 28% by 2050. While an aging population is generally seen as positive for more conservative political parties, the rise in the proportion of undecided swing voters over the last decade poses significant challenges for all established political groupings. This event, which also marks the UN International Day of Older Persons, will provide an analysis of how seniors voted in the 2014 European Parliament elections using research undertaken by the University of Leuven in association with the Martens Centre and the European Seniors Union. Entitled Seniors in the 2014 European Parliament Elections: Turnout, Voting Intentions and Representation, this research by Lawrence Cappelle, Gilles Pittoors and Steven Van Hecke is the most comprehensive analysis of its type and represents a further step in fostering our understanding of seniors’ voting patterns and motivations.
