The ageing of society looms large as having a huge impact on the future political landscape, and is increasingly being acknowledged as a serious threat to the sustainability of democracy. The ageing of the voting electorate is contributing to the political imbalance between the old and young generations, and has the potential to levy excessive burden on future generations. With this background in mind, this research seeks to point out, through reform of the electoral system, the,problems of silver democracy caused by societal ageing, and to suggest ways to achieve political equilibrium between generations. Key suggestions are: 1) changing the basis of electoral districts from geographic area to age-cohort; 2) establishment of a new future generations district which can speak for the rights of those who are currently underage; and 3) weighting of votes cast by the younger generations, who may be at a numerical disadvantage in elections.
