of an election. Electoral systems are used in politics to elect governments, while non-political elections may take place in business, <a href="/wiki/Nonprofit_organization" title="Nonprofit organization">non-profit organisations</a> and informal organisations. These rules govern all aspects of the voting process: when elections occur, <a href="/wiki/Suffrage" title="Suffrage">who is allowed to vote</a>, <a href="/wiki/Nomination_rules" title="Nomination rules">who can stand</a> as a <a href="/wiki/Candidate" title="Candidate">candidate</a>, <a href="/wiki/Voting_method" class="mw-redirect" title="Voting method">how ballots are marked and cast</a>, how the ballots are counted, how votes translate into the election outcome, limits on <a href="/wiki/Campaign_finance" title="Campaign finance">campaign spending</a>, and other factors that can affect the result. Political electoral systems are defined by constitutions and electoral laws, are typically conducted by <a href="/wiki/Election_commission" title="Election commission">election commissions</a>, and can use multiple types of elections for different offices. </p><p>Some electoral systems elect a single winner to a unique position, such as prime minister, president or governor, while others elect multiple winners, such as members of parliament or boards of directors. When electing a <a href="/wiki/Legislature" title="Legislature">legislature</a>, areas may be divided into constituencies with one or more representatives or the electorate may elect representatives as a single unit. Voters may vote directly for an individual candidate or for a list of candidates put forward by a <a href="/wiki/Political_party" title="Political party">political party</a> or <a href="/wiki/Electoral_alliance" title="Electoral alliance">alliance</a>. There are many variations in electoral systems. </p><p>The <a href="/wiki/Mathematics" title="Mathematics">mathematical</a> and <a href="/wiki/Normative_economics" class="mw-redirect" title="Normative economics">normative</a> study of voting rules falls under the branches of <a href="/wiki/Economics" title="Economics">economics</a> called <a href="/wiki/Social_choice_theory" title="Social choice theory">social choice</a> and <a href="/wiki/Mechanism_design" title="Mechanism design">mechanism design</a>, but the question has also engendered substantial contributions from <a href="/wiki/Political_science" title="Political science">political scientists</a>, <a href="/wiki/Analytic_philosophy" title="Analytic philosophy">analytic philosophers</a>, <a href="/wiki/Computer_science" title="Computer science">computer scientists</a>, and <a href="/wiki/Mathematics" title="Mathematics">mathematicians</a>.

This is sometimes referred to as a type of majority voting, although usually only a plurality is required in the last round, and sometimes even in the first round winners can avoid a second round without achieving a majority. In social choice theory, runoff systems are not called majority voting, as this term refers to <a href="/wiki/Condorcet_method" title="Condorcet method">Condorcet-methods</a>. </p><p>There are two main forms of runoff systems, one conducted in a single round of voting using <a href="/wiki/Ranked_voting_system" class="mw-redirect" title="Ranked voting system">ranked voting</a> and the other using multiple elections, to successively narrow the field of candidates. Both are primarily used for single-member constituencies. </p><p>Runoff can be achieved in a single election using <a href="/wiki/Instant-runoff_voting" title="Instant-runoff voting">instant-runoff voting</a> (IRV), whereby voters rank candidates in order of preference; this system is used for parliamentary elections in <a href="/wiki/Australia" title="Australia">Australia</a> and <a href="/wiki/Papua_New_Guinea" title="Papua New Guinea">Papua New Guinea</a>. If no candidate receives a majority of the vote in the first round, the second preferences of the lowest-ranked candidate are then added to the totals. This is repeated until a candidate achieves over 50% of the number of valid votes. If not all voters use all their preference votes, then the count may continue until two candidates remain, at which point the winner is the one with the most votes. A modified form of IRV is the <a href="/wiki/Contingent_vote" title="Contingent vote">contingent vote</a> where voters do not rank all candidates, but have a limited number of preference votes. If no candidate has a majority in the first round, all candidates are excluded except the top two, with the highest remaining preference votes from the votes for the excluded candidates then added to the totals to determine the winner. This system is used in <a href="/wiki/Sri_Lanka" title="Sri Lanka">Sri Lankan</a> presidential elections, with voters allowed to give three preferences.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">&#91;</span>4<span class="cite-bracket">&#93;</span></a></sup> </p><p>The other main form of runoff system is the <a href="/wiki/Two-round_system" title="Two-round system">two-round system</a>, which is the most common system used for presidential elections around the world, being used in 88 countries. It is also used in 20 countries for electing the legislature.<sup id="cite_ref-IDEA_1-4" class="reference"><a href="#cite_note-IDEA-1"><span class="cite-bracket">&#91;</span>1<span class="cite-bracket">&#93;</span></a></sup> If no candidate achieves a majority of votes in the first round of voting, a second round is held to determine the winner. In most cases the second round is limited to the top two candidates from the first round, although in some elections more than two candidates may choose to contest the second round; in these cases the second round is decided by plurality voting. Some countries use a modified form of the two-round system, such as <a href="/wiki/Ecuador" title="Ecuador">Ecuador</a> where a candidate in the presidential election is declared the winner if they receive 40% of the vote and are 10% ahead of their nearest rival,<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">&#91;</span>5<span class="cite-bracket">&#93;</span></a></sup> or Argentina (45% plus 10% ahead), where the system is known as <a href="/wiki/Ballotage_in_Argentina" title="Ballotage in Argentina">ballotage</a>. In some cases, a runoff may be held using a different system, as in <a href="/wiki/Contingent_election" title="Contingent election">contingent elections</a> when no candidate wins a majority of the <a href="/wiki/Electoral_College_(United_States)" class="mw-redirect" title="Electoral College (United States)">United States Electoral College</a>. </p><p>An <a href="/wiki/Exhaustive_ballot" title="Exhaustive ballot">exhaustive ballot</a> is not limited to two rounds, but sees the last-placed candidate eliminated in each round of voting.

As a result, some countries have <a href="/wiki/Leveling_seat" title="Leveling seat">leveling seats</a> to award to parties whose seat totals are lower than their proportion of the national vote. </p><p>In addition to the <a href="/wiki/Electoral_threshold" title="Electoral threshold">electoral threshold</a> (the minimum percentage of the vote that a party must obtain to win seats), there are several different ways to allocate seats in proportional systems. There are two main types of systems: <a href="/wiki/Highest_averages_method" title="Highest averages method">highest average</a> and <a href="/wiki/Largest_remainder_method" class="mw-redirect" title="Largest remainder method">largest remainder</a>. Highest average systems involve dividing the votes received by each party by a <i>divisor</i> or <i>vote average</i> that represents an idealized <a href="/wiki/Seats-to-votes_ratio" title="Seats-to-votes ratio">seats-to-votes ratio</a>, then rounding normally. In the largest remainder system, parties' vote shares are divided by an <a href="/wiki/Electoral_quota" title="Electoral quota">electoral quota</a>. This usually leaves some seats unallocated, which are awarded to parties based on which parties have the largest number of "leftover" votes. </p><p><a href="/wiki/Single_transferable_vote" title="Single transferable vote">Single transferable vote</a> (STV) is another form of proportional representation. In STV, multi-member districts are used and each voter casts one vote, being a <a href="/wiki/Ranked_voting_system" class="mw-redirect" title="Ranked voting system">ranked</a> ballot marked for individual candidates, rather than voting for a party list. STV is used in <a href="/wiki/Malta" title="Malta">Malta</a> and the <a href="/wiki/Republic_of_Ireland" title="Republic of Ireland">Republic of Ireland</a>. To be certain of being elected, candidates must pass a quota (the <a href="/wiki/Droop_quota" title="Droop quota">Droop quota</a> being the most common). Candidates that pass the quota are elected. If necessary to fill seats, votes are transferred from the least successful candidates. Surplus votes held by successful candidates may also be transferred. Eventually all seats are filled by candidates who have passed the quota or there are only as many remaining candidates as the number of remaining seats.<sup id="cite_ref-IDG_10-1" class="reference"><a href="#cite_note-IDG-10"><span class="cite-bracket">&#91;</span>10<span class="cite-bracket">&#93;</span></a></sup> </p><p>Under <a href="/wiki/Single_non-transferable_vote" title="Single non-transferable vote">single non-transferable vote</a> (SNTV) voters can vote for only one candidate, with the candidates receiving the most votes declared the winners; this system is used in <a href="/wiki/Kuwait" title="Kuwait">Kuwait</a>, the <a href="/wiki/Pitcairn_Islands" title="Pitcairn Islands">Pitcairn Islands</a> and <a href="/wiki/Vanuatu" title="Vanuatu">Vanuatu</a>.<sup id="cite_ref-IDEA_1-5" class="reference"><a href="#cite_note-IDEA-1"><span class="cite-bracket">&#91;</span>1<span class="cite-bracket">&#93;</span></a></sup> </p> <div class="mw-heading mw-heading4"><h4 id="Mixed_systems">Mixed systems</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Electoral_system&amp;action=edit&amp;section=8" title="Edit section: Mixed systems"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure typeof="mw:File/Thumb"><a href="/wiki/File:Electoral_systems_map_mixed.svg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/d/da/Electoral_systems_map_mixed.svg/250px-Electoral_systems_map_mixed.svg.png" decoding="async" width="250" height="127" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/d/da/Electoral_systems_map_mixed.svg/375px-Electoral_systems_map_mixed.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/d/da/Electoral_systems_map_mixed.svg/500px-Electoral_systems_map_mixed.svg.png 2x" data-file-width="2754" data-file-height="1398" /></a><figcaption>Countries using a mixed electoral system (lower house or unicameral legislature):<br /><b>Compensatory</b> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r981673959"><div class="legend"><span class="legend-color mw-no-invert" style="background-color:#5a2ca0; color:white;">&#160;</span>&#160;Mixed-member proportional (<a href="/w/index.php?title=Seat_linkage&amp;action=edit&amp;redlink=1" class="new" title="Seat linkage (page does not exist)">seat linkage</a>) type compensatory</div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r981673959"><div class="legend"><span class="legend-color mw-no-invert" style="background-color:#8D5FD3; color:black;">&#160;</span>&#160;<a href="/wiki/Vote_linkage" title="Vote linkage">Vote linkage</a> type partially compensatory (supermixed)</div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r981673959"><div class="legend"><span class="legend-color mw-no-invert" style="background-color:#ffaaee; color:black;">&#160;</span>&#160;Majority jackpot</div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r981673959"><div class="legend"><span class="legend-color mw-no-invert" style="background-color:#dd85ad; color:black;">&#160;</span>&#160;Two round majority jackpot</div> <b>Non-compensatory</b> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r981673959"><div class="legend"><span class="legend-color mw-no-invert" style="background-color:#FF00CC; color:black;">&#160;</span>&#160;Parallel voting (Party list + FPTP)</div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r981673959"><div class="legend"><span class="legend-color mw-no-invert" style="background-color:#8B008B; color:white;">&#160;</span>&#160;Parallel voting (Party list + TRS)</div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r981673959"><div class="legend"><span class="legend-color mw-no-invert" style="background-color:#DA0077; color:white;">&#160;</span>&#160;Parallel voting (Party list + BV/PBV)</div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r981673959"><div class="legend"><span class="legend-color mw-no-invert" style="background-color:#550088; color:white;">&#160;</span>&#160;<a href="/wiki/Majority_bonus" class="mw-redirect" title="Majority bonus">Majority bonus</a> (fusion)</div> </figcaption></figure> <p>In several countries, <a href="/wiki/Mixed_electoral_system" title="Mixed electoral system">mixed systems</a> are used to elect the legislature.
