Proportional representation (PR) refers to any type of electoral system under which subgroups of an electorate are reflected proportionately in the elected body. The concept applies mainly to political divisions among voters. The essence of such systems is that all votes cast – or almost all votes cast – contribute to the result and are effectively used to help elect someone – not just a bare plurality or (exclusively) the majority – and that the system produces mixed, balanced representation reflecting how votes are cast.
Mixed-member proportional representation is a mixed electoral system in which votes are cast for both local elections and also for overall party vote tallies, which are used to allocate additional members to produce or deepen overall proportional representation.
Electoral reform in New Zealand has been a political issue in the past as major changes have been made to both parliamentary and local government electoral systems.
Canada holds elections for legislatures or governments in several jurisdictions: for the federal (national) government, provincial and territorial governments, and municipal governments. Elections are also held for self-governing First Nations and for many other public and private organizations including corporations and trade unions. Municipal elections can also be held for both upper-tier and lower-tier governments.
The Citizens' Assembly on Electoral Reform was created by the government of British Columbia, Canada to investigate changes to the provincial electoral system. On October 25, 2004, the citizens' assembly proposed replacing the province's existing first past the post (FPTP) system with BC-STV, a single transferable vote (STV) system. This recommendation was put to the electorate in a referendum in 2005 held during that year's provincial election. The provincial government required the referendum to achieve a super-majority of 60 percent of voters and simple majorities in 60 percent of the 79 districts in order to pass. The second of these thresholds was easily met, with a majority supporting the reform in 77 out of 79 electoral districts, but the overall vote fell short of the 60 percent requirement, with 57.69 percent of the votes in favour. A second referendum in 2009 on adopting the STV system also failed to pass carrying 8 electoral districts and 39.09 percent of the overall vote.
A referendum was held in the Canadian province of British Columbia on May 17, 2005, to determine whether or not to adopt the recommendation of the Citizens' Assembly on Electoral Reform to replace the existing first-past-the-post electoral system (FPTP) with a single transferable vote system (BC-STV). It was held in conjunction with the BC Legislative Assembly election of 2005. Voters were given two ballots at that time: a ballot to vote for a Member of the Legislative Assembly of British Columbia (MLA) in their constituency and a referendum ballot. The referendum received considerable support from the electorate but failed in meeting the 60-percent threshold that had been set. A second referendum was held in 2009.
A referendum was held on October 10, 2007, on the question of whether to establish a mixed member proportional representation (MMP) system for elections to the Legislative Assembly of Ontario. The vote was strongly in favour of the existing plurality voting or first-past-the-post (FPTP) system.
The Gallagher index measures an electoral system's relative disproportionality between votes received and seats in a legislature. As such, it measures the difference between the percentage of votes each party gets and the percentage of seats each party gets in the resulting legislature, and it also measures this disproportionality from all parties collectively in any one given election. That collective disproportionality from the election is given a precise score, which can then be used in comparing various levels of proportionality among various elections from various electoral systems. The Gallagher index is a statistical analysis methodology utilised within political science, notably the branch of psephology.
BC-STV is the proposed voting system recommended by the Citizens' Assembly on Electoral Reform in October 2004 for use in British Columbia, and belongs to the single transferable vote family of voting systems. BC-STV was supported by a majority of the voters in a referendum held in 2005 but the government had legislated that it would not be bound by any vote lower than 60 percent in favour. Because of the strong majority support for BC-STV, the government elected to stage a second referendum in 2009, but with increased public funding for information campaigns to better inform the electorate about the differences between the existing and proposed systems. The leadership of both the "yes" side and the "no" side were assigned by the government. The proposal was rejected with 60.9 percent voting against, vs. 39.1 percent in favour, in the 2009 vote.
The Royal Commission on the Electoral System was formed in New Zealand in 1985 and reported in 1986. The decision to form the Royal Commission was taken by the Fourth Labour government, after the Labour Party had received more votes, yet it won fewer seats than the National Party in both the 1978 and 1981 elections. It was also a reaction to the power displayed by Prime Minister Robert Muldoon, whose action of illegally abolishing the Superannuation scheme in 1975 without any repercussions highlighted the need to distribute power in a more democratic way. The Royal Commission's report Towards a Better Democracy was instrumental in effecting New Zealand to change its electoral system from first-past-the-post to mixed member proportional.
The Politics of British Columbia involve not only the governance of British Columbia, Canada, and the various political factions that have held or vied for legislative power, but also a number of experiments or attempts at political and electoral reform.
Following the 2005 electoral reform referendum, British Columbia held a second referendum on electoral reform in conjunction with the provincial election on May 12, 2009. As in 2005, voters in 2009 were asked were asked which electoral system should be used to elect legislators: the existing first-past-the-post electoral system or the BC single transferable vote electoral system (BC-STV) proposed by the British Columbia Citizen's Assembly on Electoral Reform to ensure more proportional representation in the provincial Legislative Assembly.
A referendum was held in the Canadian province of Prince Edward Island on November 28, 2005, to determine whether to adopt the Mixed Member Proportional (MMP) system as recommended by the Prince Edward Island Electoral Reform Commission in 2003.
The 2011 New Zealand voting system referendum was a referendum on whether to keep the existing mixed member proportional (MMP) voting system, or to change to another voting system, for electing Members of Parliament to New Zealand's House of Representatives. It was held on 26 November 2011 in conjunction with the 2011 general election.
Electoral reform is a change in electoral systems which alters how public desires are expressed in election results.
Dual-member proportional representation (DMP), also known as dual-member mixed proportional, is an electoral system designed to produce proportional election results across a region by electing two representatives in each of the region’s districts. The first seat in every district is awarded to the candidate who receives the most votes, similar to first-past-the-post voting (FPTP). The second seat is awarded to one of the remaining district candidates so that proportionality is achieved across the region, using a calculation that aims to award parties their seats in the districts where they had their strongest performances.
A non-binding referendum on electoral reform was held in the Canadian province of Prince Edward Island between 27 October – 7 November 2016. This was the second electoral reform referendum to be held in Prince Edward Island, following a vote to maintain the status quo in 2005. The referendum asked which of five voting systems residents would prefer to use in electing members to the Legislative Assembly of Prince Edward Island. The referendum involved four counts under Instant-runoff voting rules and at the end, mixed member proportional representation was the majority choice with 55.03% support on the final ballot, with support of 52.42% of votes cast.
A referendum on electoral reform took place by mail-in ballot between October 22 and December 7, 2018, in the Canadian province of British Columbia. 61.3 percent of voters supported maintaining the first-past-the-post voting system rather than switching to a proportional representation voting system, which was supported by 38.7 percent of voters. This was British Columbia's third referendum on electoral reform, following ones in 2005 and 2009.
Rural–urban proportional representation (RUP), also called flexible district PR, is a mixed electoral system which combines the use of single- and multi-member constituencies in a lower tier and top-up seats in an upper tier to meet the different needs of both rural and urban areas, while protecting the objective of proportionality. The term was coined by Fair Vote Canada, which devised a rural–urban system with the intention of meeting the special challenges of Canada's geography, which includes wide-flung, sparsely populated areas.
A referendum on electoral reform was held on April 23, 2019, in the Canadian province of Prince Edward Island – simultaneously with the 2019 provincial election – to determine if the province should adopt a mixed-member proportional representation voting system (MMP). A narrow majority voted to keep the existing first-past-the-post system. However, the referendum was not binding, as neither the yes or no side received majority support in 60% or more of the province's 27 electoral districts.
