Even where old enough to vote, young people tend to be less well integrated than older groups into electoral and political processes as reflected partly in their lower voter turnout. The correlation is not proof of causality, but it does suggest to some researchers that societies must make greater efforts to increase opportunities for education, jobs, livelihoods and political engagement for their youth. This tendency, if not counterbalanced by hope for a better future, can sometimes lead young people to become involved in violence (Urdal, 2006).
