High Quality Content by WIKIPEDIA articles! Proportional representation (PR) is a concept in voting systems used to elect an assembly or council. PR means that the number of seats won by a party or group of candidates is proportionate to the number of votes received. For example, under a PR voting system if 30% of voters support a particular party then roughly 30% of seats will be won by that party. PR is an alternative to voting systems based on single member districts or on bloc voting; these non-PR systems tend to produce disproportionate outcomes and to have a bias in favour of larger political groups. PR systems tend to produce a proliferation of political parties, while single member districts encourage a two-party system.
