When the [[single transferable vote]] (STV) [[voting system]] is applied to a single-winner election it is sometimes called '''instant-runoff voting''' (IRV), as it is much like holding a series of [[runoff voting|runoff]] elections in which the lowest polling candidate (based on 1st choice votes; see [[Ranked ballot|ranked ballot]]) is eliminated in each round until someone receives a [[simple majority|majority]]
Outside the US, IRV is known as the '''[[Alternative Vote]]''', '''[[preferential voting]]''', '''single-winner STV''', or the '''[[Thomas Hare|Hare]] System''', though there is room for confusion with some of these terms, since they can also refer to STV in general. In the US, IRV is also known as '''Ranked Choice Voting''' ('''RCV'''), a term preferred by election officials in San Francisco in 2004 because election results were not instant, and voters are responsible for ranking candidates.<ref>As described on a [https://web.archive.org/web/20040514072509/http://www.ci.sf.ca.us/site/election_page.asp?id=24269 City of San Francisco election page in 2004] "''Is 'ranked-choice voting' the same as 'instant runoff voting'? In San Francisco, ranked-choice voting is sometimes called 'instant run-off voting.' The Department of Elections generally uses the term ranked-choice voting, because it describes the voting method—voter are directed to rank their first, second and third choice candidates. The Department also uses the term ranked-choice voting because the word 'instant' might create an expectation that final results will be available immediately after the polls close on election night. But the term 'instant run-off' does not mean instantaneous reporting of results—the term means that there is no need for a separate run-off election.''"</ref>
