Proportional representation (PR) refers to a 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.
Party-list proportional representation (list-PR) is a subset of proportional representation electoral systems in which multiple candidates are elected through their position on an electoral list. They can also be used as part of mixed-member electoral systems.
The single transferable vote (STV), sometimes known as proportional ranked choice voting (P-RCV), is a multi-winner electoral system in which each voter casts a single vote in the form of a ranked-choice ballot. Voters have the option to rank candidates, and their vote may be transferred according to alternate preferences if their preferred candidate is eliminated or elected with surplus votes, so that their vote is used to elect someone they prefer over others in the running. STV aims to approach proportional representation based on votes cast in the district where it is used, so that each vote is worth about the same as another.
Elections in Sweden are held once every four years. At the highest level, all 349 members of Riksdag, the national parliament of Sweden, are elected in general elections. Elections to the 20 county councils and 290 municipal assemblies – all using almost the same electoral system – are held concurrently with the legislative elections on the second Sunday in September.
The additional-member system (AMS) is a mixed electoral system under which most representatives are elected in single-member districts (SMDs), and the other "additional members" are elected to make the seat distribution in the chamber more proportional to the way votes are cast for party lists. It is distinct from parallel voting in that the "additional member" seats are awarded to parties taking into account seats won in SMDs, which is not done under parallel voting.
The Australian electoral system comprises the laws and processes used for the election of members of the Australian Parliament and is governed primarily by the Commonwealth Electoral Act 1918. The system presently has a number of distinctive features including compulsory enrolment; compulsory voting; majority-preferential instant-runoff voting in single-member seats to elect the lower house, the House of Representatives; and the use of the single transferable vote proportional representation system to elect the upper house, the Senate.
Electoral systems of the Australian states and territories are broadly similar to the electoral system used in federal elections in Australia.
Norway elects its legislature on a national level. The parliament, the Storting, has 169 members elected for a four-year term by a form of proportional representation in multi-seat constituencies.
Open list describes any variant of party-list proportional representation where voters have at least some influence on the order in which a party's candidates are elected. This is as opposed to closed list, which allows only active members, party officials, or consultants to determine the order of its candidates and gives the general voter no influence at all on the position of the candidates placed on the party list.
The House of Assembly, or Lower House, is one of the two chambers of the Parliament of Tasmania in Australia. The other is the Legislative Council or Upper House. It sits in Parliament House in the state capital, Hobart.
There are five types of elections in Slovakia: municipal elections, regional elections, parliamentary elections, presidential elections and elections to the European Parliament. All four types of elections are normally held after fixed periods, although early elections can occur in certain situations. Elections are conventionally scheduled for a Saturday - the polls normally open at 7:00 in the morning and close at 22:00 in the evening. Citizens aged 18 years or older are eligible to vote. Those serving prison sentences for particularly serious crimes, as well as those deprived of legal capacity, including persons with mental disabilities, are denied the right to vote. Voter registration is passive and decentralized with the voter register maintained by municipalities based on the permanent residence register. Voter lists are updated continuously based on municipal records and input provided by state institutions or other municipalities. Voters may verify their data in voter lists, and, if necessary, request correction until the day before election day. On election day, a voter can be added to a voter list upon presenting an identity card with proof of residency. Some 4.4 million voters are registered and valid to vote in the elections. Voters are only able to vote from abroad during the Parliamentary Elections in Slovakia.
In electoral systems which use ranked voting, a donkey vote is a cast ballot where the voter ranks the candidates based on the order they appear on the ballot itself. The voter that votes in this manner is referred to as a donkey voter.
In electoral systems, a wasted vote is any vote that does not receive representation in the final election outcome. Plurality voting systems have the greatest number of wasted votes.
Historically, the single transferable vote (STV) electoral system has seen a series of relatively modest periods of usage and disusage throughout the world; however, today it is seeing increasing popularity and proposed implementation as a method of proportional representation and a goal of electoral reform. STV has been used in many different local, regional and national electoral systems, as well as in various other types of bodies, around the world.
There are a number of complications and issues surrounding the application and use of single transferable vote proportional representation that form the basis of discussions between its advocates and detractors.
Panachage is the name given to a procedure provided for in several open-list variants of the party-list proportional representation system. It gives voters more than one vote in the same ballot and allows them to distribute their votes between or among individual candidates from different party lists. Seats are allocated to parties based on party vote share, with the seats of a party going to the most-popular candidate(s) of that party.
An electoral system or voting system is a set of rules that determine how elections and referendums are conducted and how their results are determined. Electoral systems are used in politics to elect governments, while non-political elections may take place in business, non-profit organisations and informal organisations. These rules govern all aspects of the voting process: when elections occur, who is allowed to vote, who can stand as a candidate, how ballots are marked and cast, how the ballots are counted, how votes translate into the election outcome, limits on campaign spending, and other factors that can affect the result. Political electoral systems are defined by constitutions and electoral laws, are typically conducted by election commissions, and can use multiple types of elections for different offices.
The Parliament of Malta is the constitutional legislative body in Malta, located in Valletta. The parliament is unicameral, with a democratically elected House of Representatives and the president of Malta. By constitutional law, all government ministers, including the prime minister, must be members of the House of Representatives.
Hare-Clark is a type of single transferable vote electoral system of proportional representation used for elections in Tasmania and the Australian Capital Territory. The method for the distribution of preferences is similar to other voting systems in Australia, such as for the Australian Senate.
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 political parties instead of individual candidates. The spare vote refers to a secondary vote (preference) of the voter, which only comes into play if the first preference for the political party preferred by the voter, is below the electoral threshold. In Germany, there were draft laws for the spare vote system in Saarland, Schleswig-Holstein and Brandenburg federal states, but they were not implemented.
