History and use of instant-runoff voting
![]() | This article includes a improve this article by introducing more precise citations. (May 2024) ) |
Instant-runoff voting (IRV) is a ranked voting method used in single-winner elections. IRV is also known outside the US as the alternative vote (AV) or preferential voting. IRV is known by different names in the various countries in which it is used. It is also known as the 'Alternative Vote', 'Ranked Choice Voting', and 'Preferential Voting', although IRV is only one of many ranked (or preferential) voting systems.
Today it is in use at the national level to elect the Australian House of Representatives, the National Parliament of Papua New Guinea, the President of Ireland and President of India. In Australia it is also used for elections to the legislative assemblies (lower houses) of all states and territories except Tasmania and the Australian Capital Territory, and for the Tasmanian Legislative Council (upper house).
IRV is also used in some municipal elections in Australia, the
Instant-runoff voting is based on the
It is also known as Ware's method, after William Robert Ware, the founder of the schools of architecture at the Massachusetts Institute of Technology (MIT) and Columbia University,[1][2] who, while describing the experience of holding a demonstration single transferable vote election in 1871, mentioned that a similar method could be used for single-winner elections.[3][4]
IRV was adopted for the Australian House of Representatives in 1918 and has been used to elect the President of Ireland since the office came into being in 1937. It was introduced in Fiji in 1999 and in Papua New Guinea in 2007.
IRV in its true form (what was called Alternative Voting at the time) was first used in Australia in 1909.
History of the use of IRV by country
Australia
The first known use of an IRV-like method in a governmental election was in the 1893 general election in the Colony of Queensland (in present-day Australia).[5] The variant used for this election was a "contingent vote", where all candidates but two are eliminated in the first round, with one of the last two elected by majority after votes of the others are transferred. Queensland used contingent voting until 1942, one of the longest uses of the system anywhere.[6]
IRV in its true form (what was called Alternative Voting at the time) was first used in
IRV was introduced for federal (nationwide) elections in Australia after the Swan by-election in October 1918, in response to the rise of the conservative Country Party, representing small farmers. The Country Party split the non-Labor vote in conservative country areas, allowing Labor candidates to win without a majority of the vote. The conservative government of Billy Hughes introduced IRV (in Australia called "preferential voting") as a means of allowing competition between the Coalition parties without putting seats at risk. It was first used at the Corangamite by-election on 14 December 1918, and at a national level at the 1919 election.[9] IRV continued to benefit the Coalition until the 1990 election, when for the first time Labor obtained a net benefit from IRV.[10]
IRV (in Australia called preferential voting) was introduced for
Ballot papers are marked with the order of preferences: 1, 2, 3, etc. Counting of the ballot papers proceeds and when no candidate receives more than 50% of the first preference vote (candidates with a number one), the candidate with the fewest first preference votes is eliminated and that candidate's votes are distributed to the remaining candidates. The process continues until a candidate accumulates 50% plus one vote, or a simple majority. Counting will continue to finality, which results in what is referred to as the two-party preferred vote, which expresses the electorate's voting preference equivalent to a 2-person election of the two most popular candidates.
A study of the 2007 federal election found that every House of Representatives electorate had at least four candidates, and the average number of candidates was seven. 76 candidates depended on preferences to win, which represented more than half of the 150 winners.[15]
Preferential voting is used for most state and local elections in Australia, but sometimes with optional preferential voting where voters are allowed to limit their number of rankings. The Australian Senate, the upper houses of four states (New South Wales, South Australia, Victoria and Western Australia), the lower house of one state (Tasmania) and the sole house of the Australian Capital Territory, use the multi-winner single transferable vote system.
In 1955, IRV was used to elect councils in five municipalities in Tasmania - Burnie, Devonport, Kentish, Latrobe and Ulverstone - and in Hobart to elect the mayor.[16]

Under the name 'preferential' or 'elimination ballot' or alternative vote,
Provincially, British Columbia used a mixture of voting methods to elect their members of the Legislative Assembly (MLAs): single-member districts using first-past-the-post and multi-member districts using through block voting. Elections in BC from the province's creation until the 1990 election were held under a mix of multi-member and single-member districts, with district types often being changed back and forth from one election to the next. Through almost all of BC's history, seats were filled by plurality elections. The only exceptions were the 1952 and 1953 elections where Instant-runoff voting was used.
Through the 1940s, the province was governed by a
By the 1950s, the coalition had begun to fall apart, resulting in the Conservatives and Liberals having to run for office separately under their own party banners. However, to try to prevent the CCF from being elected, one of the last acts of the coalition government was to introduce the alternative voting system (known today in the US as instant-runoff voting), which was implemented for the 1952 general election. IRV was brought in even in multi-seat districts by the innovation that each seat would be filled by a separate contests, two or even three separate ballots and contests in a district.
In each contest in a district, rather than voting for one candidate by marking an "X" on the ballot, an elector ranked the candidates running in the contest by placing numbers next to their names on the ballot. (They could rank as few or as many candidates as they desired.) The candidate marked with a 1 received the vote in the first count. In the first count, if a candidate received a majority of first preferences marked by voters, that candidate was declared elected with no vote transfers being conducted. If not, the candidate with the fewest votes was dropped and the candidate's ballots were re-allocated to the remaining candidates based on the second choices marked on the ballots. This procedure was repeated again and again if necessary until a candidate received a majority of votes.
The result of using this voting method (plus completely different voting behavior by many BC voters) was the unexpected election of enough MLAs of the
The SoCred minority government lasted only nine months before losing a vote in the Legislature and an election having to be called. Alternative voting was again employed in this general election. The result this time was a SoCred majority.[citation needed]
After this second IRV election, the SoCreds abolished the preferential voting system and returned the province to the province's traditional mixed system of block voting in multiple-member constituencies and FPTP contests in single-member districts. The change-back benefited the government party by creating large numbers of wasted votes and a wide possibility for gerrymandering. Finally in the 1980s, this unfair system was discarded due to wide criticism, and the province adopted a consistent system of FPTP in single-seat districts. In the next election many CCF supporters chose the relatively unknown Social Credit Party, a minor party that had never held any seats in the British Columbia legislature, as their second choice. The Social Credit Party achieved an upset victory in the 1952 election, winning 19 seats in the 48-member legislature to 18 for the CCF, 6 for the Liberals and 4 for the Conservatives. The Socreds formed a short-lived minority government until the 1953 election, in which they won a majority of seats (28 of 48). After the 1953 election, the Liberal and renamed Progressive Conservative Parties were reduced to third parties in the province, and first-past-the-post was reinstated by the government.[citation needed]
IRV was also used for provincial elections in Alberta (1926–1955 in rural districts), and Manitoba (1927–1953) outside Winnipeg (excluding St. Boniface in 1949 and 1953). IRV was also used in provincial by-elections in these two provinces between 1924 and 1955.[19][20]
IRV has never been used for federal elections.
IRV was used in city elections in Lethbridge from 1913 to 1927.
IRV was used to elect mayors in city elections when STV was used to elect city councillors. STV/IRV was used in 20 Canadian cites during the 20th Century.
IRV is used for certain party and private elections in Canada, including such large-scale elections at the Canadian Wheat Board,[21] the 2006 Progressive Conservative Association of Alberta leadership election, where it has generated high turnout,[22] and the 2011 British Columbia Liberal Party leadership election. The Liberal Party of Canada had adopted IRV with a national primary for its leadership elections.[23]
In 2014, the Province of Ontario announced that municipalities would have the option to use IRV for local elections starting in 2018,[24] and authorizing legislation was passed in 2016.[25] London, Ontario became the first city to use ranked choice voting in 2018.[26] Cambridge and Kingston were set to adopt IRV in the 2022 elections.[27] However, in 2020, the Legislative Assembly of Ontario passed a law repealing the option to use IRV in municipal elections. As a result, every city in Ontario used the First Past the Post system in 2022, making the 2018 London election the only one to use IRV under this legislation.[28]

Estonia
The small Baltic state of Estonia held its first post-Soviet elections in 1992. It used a combination of IRV (for president) and STV (for legislators) — a system that had been popularized by Rein Taagepera, an expatriate Estonian political scientist at the University of California.[17]
Hong Kong
IRV was used to elect a small number of functional constituencies of the Legislative Council of Hong Kong until the 2021 Hong Kong electoral changes.
Hungary
IRV has not been used for national or local elections. For the first time in 2024, a broad opposition primary election in the 12th district of Budapest was held via IRV, locally known as "instant multi-round voting" ("azonnali többfordulós szavazás").[32] Certain organizations, like the Two-Tailed Dog Party and some student unions use IRV to elect their officials[citation needed].

Multi-winner single transferable vote (STV) is used for all district health board elections in New Zealand.[48] In 2004, several New Zealand cities and local authorities began to use STV for their elections—including the nation's second-largest city and capital, Wellington, and its fifth-largest city, Dunedin [49] Where electing a mayor directly, these cities used instant runoff voting. In 2007, for example, Wellington's mayor Kerry Prendergast was elected over 10 rivals on the 9th round of counting.[50] Other IRV races that involved multiple rounds of counting included the 2010 Dunedin mayoral election and 2010 Wellington City mayoral election. As of September 2013, seven local authorities in New Zealand were elected using STV.

IRV (again under the name preferential vote[52]) was used on the initial ballot of the 2015–2016 New Zealand flag referendums for voters to choose among five flag options.
Papua New Guinea
A form of IRV has been used to elect members of parliament since last plurality voting election in 2002. Called "limited preferential voting" because voters are limited to ranking three candidates, the system has been credited with reducing election violence in a highly fractured political system.[53] IRV has been used since 2003 for the national parliament election, where voters are limited to ranking three candidates.[54][55]

IRV has been debated vigorously in the country since the early 20th century. In 1917, for example, the Speaker's Conference advocated the adoption of IRV for 358 of the 569 constituencies in the UK, and STV for the rest; its intention was that STV would be used in densely populated urban areas but, in order to keep constituencies from being too large, IRV would be used in more sparsely populated rural areas. Although the

Since 1912, IRV has been adopted and repealed in various United States jurisdictions.
Between 1912 and 1930, limited forms of RCV (typically with only two rankings[69]) were implemented, with 24 cities using proportional RCV before repeal in some areas (Florida, Indiana, Maryland, Minnesota, and Wisconsin) Proportional RCV has been used continuously in Cambridge, Massachusetts since 1941.
Since 2002, IRV has been adopted by more than a dozen cities, with some adoptions pending implementation.
Jurisdictions that have implemented and then repealed IRV include Ann Arbor, Michigan (1974–1976);[70] Pierce County, Washington (2006–2009);[71] Burlington, Vermont (2005–2010);[72] Aspen, Colorado (2007–2010);[73] and in North Carolina (2006–2013).
As of October 2022, American cities and counties currently using IRV to elect at least one office included
San Francisco's system of IRV was challenged in federal court, but a unanimous panel of the US Court of Appeals for the 9th Circuit upheld San Francisco's IRV law, finding that the plaintiff failed to establish that the City's chosen electoral system was unconstitutional.[75]
Private organizations in the U.S. that use IRV[76] include the Hugo Awards for science fiction,[77] the Academy of Motion Picture Arts and Sciences in selection of the Oscar for Best Picture,[78] and more than fifty colleges and universities for student elections.[79]
Six states planned to use RCV in the 2020 Democratic Party presidential primaries: Alaska, Hawaii, Kansas, and Wyoming for all voters; Iowa and Nevada for absentee voters.[84] Rather than eliminating candidates until a single winner is chosen, voters' choices would be reallocated until all remaining candidates have at least 15%, the threshold to receive delegates to the convention.[85]
