Proportional Representation

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. There are many different forms of proportional representation. Some are focused solely on achieving the proportional representation of different political parties (such as list PR) while others permit the voter to choose between individual candidates (such as PR-STV). The degree of proportionality also varies; it is determined by factors such as the precise formula used to allocate seats, the number of seats in each constituency or in the elected body as a whole, and the level of any minimum threshold for election.

Famous quotes containing the word proportional:

    The Humanity of men and women is inversely proportional to their Numbers. A Crowd is no more human than an Avalanche or a Whirlwind. A rabble of men and women stands lower in the scale of moral and intellectual being than a herd of Swine or of Jackals.
    Aldous Huxley (1894–1963)
