Vote Threshold

TheInfoList



OR:

The electoral threshold, or election threshold, is the minimum share of the primary vote that a candidate or political party requires to achieve before they become entitled to representation or additional seats in a legislature. This limit can operate in various ways, e.g. in party-list proportional representation systems where an electoral threshold requires that a party must receive a specified minimum percentage of votes (e.g. 5%), either nationally or in a particular electoral district, to obtain seats in the legislature. In Single transferable voting the election threshold is called the quota and not only the first choice but also the next-indicated choices are used to determine whether or not a party passes the electoral threshold (and it is possible to be elected under STV even if a candidate does not pass the election threshold). In MMP systems the election threshold determines which parties are eligible for the top-up seats. The effect of an electoral threshold is to deny representation to small parties or to force them into coalitions, with the presumption of rendering the election system more stable by keeping out fringe parties. Proponents say that simply having a few seats in a legislature can significantly boost the profile of a fringe party and that providing representation and possibly veto power for a party that receives only 1% of the vote not be appropriate; however, critics posit that in the absence of a ranked ballot system (such as the
spare vote The spare vote is a version of single transferable voting applied to the ranking of parties, first proposed for elections in Germany in 2013. This preferential party system is a ranked proportional representation electoral system applying to polit ...
), supporters of minor parties are effectively disenfranchised and denied the right of representation by someone of their choosing. Two boundaries can be defined—a threshold of representation is the minimum vote share that might yield a party a seat under the most favorable circumstances for the party, while the threshold of exclusion is the maximum vote share that could be insufficient to yield a seat under the least favorable circumstances. Arend Lijphart suggested calculating the informal threshold as the mean of these. Some MMP systems allow a party that wins a local seat to be eligible for top-up seats even if it does not exceed the election threshold.


Recommendations for electoral thresholds

The Parliamentary Assembly of the Council of Europe recommends for parliamentary elections a threshold not higher than 3%. For single transferable vote in part to keep the natural threshold below 10%, some scholar recommend a district magnitude higher than 3.


Electoral thresholds in various countries

In Poland's Sejm, Lithuania's Seimas, Germany's Bundestag and New Zealand's House of Representatives, the threshold is 5% (in Poland, additionally 8% for a coalition of two or more parties submitting a joint
electoral list An electoral list is a grouping of candidates for election, usually found in proportional or mixed electoral systems, but also in some plurality electoral systems. An electoral list can be registered by a political party (a party list) or can ...
and in Lithuania, additionally 7% for coalition). However, in Germany and New Zealand, if a party wins a minimum number of directly elected seats—three in Germany and one in New Zealand—the threshold does not apply (in Germany the directly elected seats are kept regardless). The threshold is 3.25% in Israel's Knesset (it was 1% before 1992, 1.5% in 1992–2003 and 2% 2003–2014) and 7% in the Turkish parliament. In Poland, ethnic minority parties do not have to reach the threshold level to get into the parliament and so there is always a small German minority representation (at minimum, one member) in the Sejm. In Romania, for the ethnic minority parties there is a different threshold than for the national parties that run for the
Chamber of Deputies The chamber of deputies is the lower house in many bicameral legislatures and the sole house in some unicameral legislatures. Description Historically, French Chamber of Deputies was the lower house of the French Parliament during the Bourbon R ...
. There are also countries such as Portugal, South Africa, Finland, the Netherlands and North Macedonia that have proportional representation systems without a legal threshold, although the Netherlands has a rule that the first seat can never be a remainder seat, which means that there is an effective threshold of 100% divided by the total number of seats (with 150 seats to allocate, this threshold is currently 0.67%).


Australia

For the Senate of Australia, which is elected through the single transferable vote (STV) form of proportional representation, the need for a formal electoral threshold is rendered moot due to the presence of small electorates that return comparatively few members to Parliament (and as such, they require a relatively high percentage of the vote (as determined through the
Droop quota The Droop quota is the quota most commonly used in elections held under the single transferable vote (STV) system. It is also sometimes used in elections held under the largest remainder method of party-list proportional representation (list PR). ...
) in order to be elected). As STV is a ranked voting system, supporters of minor parties are not disenfranchised as their votes are redistributed to other candidates according to the individual's indicated 2nd and further preferences.


Germany

Germany, as mentioned earlier, has a regular threshold of 5%, but a party winning three constituency seats in the Bundestag can gain additional representation even if it has achieved under 5% of the total vote, and ethnic minority parties have no threshold. The 2021 election demonstrated both thresholds: The Left still qualified for list votes despite getting just 4.9%, because they held three direct mandate seats, and the South Schleswig Voters' Association entered the Bundestag with just 0.1% as a registered party for Danish and Frisian minorities.


Norway

In Norway, the nationwide electoral threshold of 4% applies only to
leveling seat Leveling seats ( da, tillægsmandat, sv, utjämningsmandat, no, utjevningsmandater, is, jöfnunarsæti, german: Ausgleichsmandat), commonly known also as adjustment seats, are an election mechanism employed for many years by all Nordic countrie ...
s. A party with sufficient local support may still win the regular district seats, even if the party fails to meet the threshold. For example, the 2021 election saw the Green Party and Christian Democratic Party each win three district seats, and Patient Focus winning one district seat despite missing the threshold.


Slovenia

In Slovenia, the threshold was set at 3 parliamentary seats during parliamentary elections in 1992 and 1996. This meant that the parties needed to win about 3.2% of the votes in order to pass the threshold. In 2000, the threshold was raised to 4% of the votes.


Sweden

In Sweden, there is a nationwide threshold of 4% for the
Riksdag The Riksdag (, ; also sv, riksdagen or ''Sveriges riksdag'' ) is the legislature and the supreme decision-making body of Sweden. Since 1971, the Riksdag has been a unicameral legislature with 349 members (), elected proportionally and se ...
, but if a party reaches 12% in one election district, it will take part in the seat allocation for that district. As of the 2018 election, nobody has been elected based on the 12% rule.


United States

In the United States, as the majority of elections are conducted under the first-past-the-post system, legal electoral thresholds do not apply in the actual voting. However, several states have threshold requirements for parties to obtain automatic ballot access to the next general election without having to submit voter-signed petitions. The threshold requirements have no practical bearing on the two main political parties (the Republican and
Democratic Democrat, Democrats, or Democratic may refer to: Politics *A proponent of democracy, or democratic government; a form of government involving rule by the people. *A member of a Democratic Party: **Democratic Party (United States) (D) **Democratic ...

parties. The threshold rules also apply for independent candidates to obtain ballot access.


List of electoral thresholds by country


Europe

The electoral threshold for elections to the European Parliament varies for each member state, a threshold of up to 5% is applied for individual electoral districts, no threshold is applied across the whole legislative body.


Non-European countries


Legal challenges

The German Federal Constitutional Court rejected an electoral threshold for the European Parliament in 2011 and in 2014 based on the principle of one person, one vote. In the case of Turkey, in 2004 the Parliamentary Assembly of the Council of Europe declared this threshold to be manifestly excessive and asked Turkey to lower it (''Council of Europe Resolution 1380 (2004)''). On 30 January 2007 the European Court of Human Rights ruled by five votes to two and on 8 July 2008, its Grand Chamber by 13 votes to four that the former 10% threshold imposed in Turkey does not violate the right to free elections (Article 3 of Protocol 1 of the ECHR). It held, however, that this same threshold could violate the Convention if imposed in a different country. It was justified in the case of Turkey in order to stabilize the volatile political situation over recent decades.


Natural threshold

creates a "hidden" natural threshold (also called an effective, or informal threshold). The number of votes that means that a party is guaranteed a seat can be calculated by the formula (\frac + \varepsilon) where ε is the smallest possible number of votes. That means that in a district with four seats slightly more than 20% of the votes will guarantee a seat. Under more favorable circumstances, the party can still win a seat with fewer votes. The most important factor in determining the natural threshold is the number of seats to be filled by the district. Other less important factors are the seat allocation formula (

), the number of contestant political parties and the size of the assembly. Generally, smaller districts leads to a higher proportion of votes needed to win a seat and vice versa. The lower bound (the threshold of representation or the percentage of the vote that allows a party to earn a seat under the most favorable circumstances) is more difficult to calculate. In addition to the factors mentioned earlier, the number of votes cast for smaller parties are important. If more votes are cast for parties that do not win any seat, that will mean a lower percentage of votes needed to win a seat.

As a result, Erdoğan's AKP gained power, winning more than two-thirds of the seats in the Parliament with just 34.28% of the vote, with only one opposition party ( CHP, which by itself failed to pass threshold in 1999) and 9 independents.

Amount of unrepresented vote

Electoral thresholds can sometimes seriously affect the relationship between the percentages of the popular vote achieved by each party and the distribution of seats. The proportionality between seat share and popular vote can be measured by the Gallagher index. While the amount of unrepresented vote is a measure of the total amount of voters not represented by any party sitting in the legislature and is related to No taxation without representation. The failure of one party to reach the threshold not only deprives their candidates of office and their voters of representation; it also changes the

every party above 1% got seats due to the electoral threshold in New Zealand of at least one seat in first-past-the-post voting, which caused a much lower unrepresented vote compared to the other years. In the Russian parliamentary elections in 1995, with a threshold excluding parties under 5%, more than 45% of votes went to parties that failed to reach the threshold. In 1998, the Russian Constitutional Court found the threshold legal, taking into account limits in its use. After the first implementation of the threshold in Poland in

34.4% of the popular vote did not gain representation. There had been a similar situation in Turkey, which had a 10% threshold, easily higher than in any other country. The justification for such a high threshold was to prevent multi-party coalitions and put a stop to the endless fragmentation of political parties seen in the 1960s and 1970s. However, coalitions ruled between 1991 and 2002, but mainstream parties continued to be fragmented and in the

66% of the seats. In the Ukrainian elections of March 2006, for which there was a threshold of 3% (of the overall vote, i.e. including invalid votes), 22% of voters were effectively disenfranchised, having voted for minor candidates. In the parliamentary election held under the same system, fewer voters supported minor parties and the total percentage of disenfranchised voters fell to about 12%. In Bulgaria, 24% of voters cast their ballots for parties that would not gain representation in the elections of

). In the Philippines where party-list seats are only contested in 20% of the 287 seats in the lower house, the effect of the 2% threshold is increased by the large number of parties participating in the election, which means that the threshold is harder to reach. This led to a quarter of valid votes being wasted, on average and led to the 20% of the seats never being allocated due to the 3-seat cap In

due to an increase in number of participating parties. These statistics take no account of the wasted votes for a party which is entitled to more than three seats but cannot claim those seats due to the three-seat cap. Electoral thresholds can produce a spoiler effect, similar to that in the first-past-the-post voting system, in which minor parties unable to reach the threshold take votes away from other parties with similar ideologies. Fledgling parties in these systems often find themselves in a

: if a party is perceived as having no chance of meeting the threshold, it often cannot gain popular support; and if the party cannot gain popular support, it will continue to have little or no chance of meeting the threshold. As well as acting against extremist parties, it may also adversely affect moderate parties if the political climate becomes polarized between two major parties at opposite ends of the political spectrum. In such a scenario, moderate voters may abandon their preferred party in favour of a more popular party in the hope of keeping the even less desirable alternative out of power. On occasion, electoral thresholds have resulted in a party winning an outright majority of seats without winning an outright majority of votes, the sort of outcome that a proportional voting system is supposed to prevent. For instance, the Turkish AKP won a majority of seats with less than 50% of votes in three consecutive elections (2002, 2007 and 2011). In the 2013 Bavarian state election, the Christian Social Union failed to obtain a majority of votes, but nevertheless won an outright majority of seats due to a record number of votes for parties which failed to reach the threshold, including the

15.7% voted for a party that did not meet the 5% threshold. In contrast, elections that use the ranked voting system can take account of each voter's complete indicated ranking preference. For example, the single transferable vote redistributes first preference votes for candidates below the threshold. This permits the continued participation in the election by those whose votes would otherwise be wasted. Minor parties can indicate to their supporters before the vote how they would wish to see their votes transferred. The single transferable vote is a proportional voting system designed to achieve proportional representation through ranked voting in ''multi-seat'' (as opposed to single seat) organizations or constituencies (voting districts). Ranked voting systems are widely used in Australia and Ireland. Other methods of introducing ordinality into an electoral system can have similar effects.
