Plurality voting refers to electoral systems in which the candidate in an electoral district who poll more than any other are elected.
Proportional representation (PR) refers to any 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. Under other election systems, a bare plurality or a scant majority are all that are used to elect candidates. Further, a PR system is one that produces mixed and balanced representation, reflecting how votes are cast.
Party-list proportional representation (list-PR) is a system of proportional representation based on preregistered political parties, with each party being allocated a certain number of seats roughly proportional to their share of the vote.
The single transferable vote (STV), a type of 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 alternative 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.
Single non-transferable vote or SNTV is an electoral system used to elect multiple winners. It is a semi-proportional variant of first-preference plurality, applied to multi-member districts where each voter casts just one vote. SNTV generally makes it unlikely that a single party will take over all seats in a city, as generally happens with winner-take-all systems. SNTV is highly similar to cumulative voting, and can be considered a variant of dot voting where each voter has only one point to assign.
Block or bloc voting refers to a class of electoral systems where multiple candidates are elected simultaneously. They do not guarantee minority representation and allow a group of voters to ensure that only their preferred candidates are elected. In these systems, a voter can select as many candidates as there are open seats. That is, the voter has as many votes to cast as the number of seats to fill. The block voting systems are among various election systems available for use in multi-member districts where the voting system allows for the selection of multiple winners at once.
Electoral systems of the Australian states and territories are broadly similar to the electoral system used in federal elections in Australia.
Closed list describes the variant of party-list systems where voters can effectively vote for only political parties as a whole; thus they have no influence on the party-supplied order in which party candidates are elected. If voters had some influence, that would be called an open list. Closed list systems are still commonly used in party-list proportional representation, and most mixed electoral systems also use closed lists in their party list component. Many countries, however have changed their electoral systems to use open lists to incorporate personalised representation to their proportional systems.
An electoraldistrict, sometimes called a constituency, riding, or ward, is a subdivision of a larger state created to provide its population with representation in the larger state's legislature. That body, or the state's constitution or a body established for that purpose, determines each district's boundaries and whether each will be represented by a single member or multiple members. Generally, only voters (constituents) who reside within the district are permitted to vote in an election held there. District representatives may be elected by a first-past-the-post system, a proportional representative system, or another voting method. They may be selected by a direct election under universal suffrage, an indirect election, or another form of suffrage.
Canada holds elections for legislatures or governments in several jurisdictions: for the federal (national) government, provincial and territorial governments, and municipal governments. Elections are also held for self-governing First Nations and for many other public and private organizations including corporations and trade unions. Municipal elections can also be held for both upper-tier and lower-tier governments.
Elections in Spain encompass four different types: general elections, regional elections, local elections, and elections to the European Parliament. General elections and regional elections are typically conducted at the conclusion of the national or regional legislative mandate, which usually spans four years since the previous election. However, early elections can be called in certain circumstances. On the other hand, local council elections and elections to the European Parliament follow fixed dates, although some local government bodies, such as provincial councils, are not directly elected. In most elections, a party-list proportional representation (PR) system is employed, while the Senate utilizes the plurality system.
The Politics of British Columbia involve not only the governance of British Columbia, Canada, and the various political factions that have held or vied for legislative power, but also a number of experiments or attempts at political and electoral reform.
A plural district was a district in the United States House of Representatives that was represented by more than one member. States using this method elected multiple members from some of their geographically defined districts. They did so on a single ballot or on separate concurrent ballots for each seat. In more modern terms, for less ambiguity, such a district is termed a multi-member district.
A party-list system is a type of electoral system that formally involves political parties in the electoral process, usually to facilitate multi-winner elections. In party-list systems, parties put forward a list of candidates, the party-list who stand for election on one ticket. Voters can usually vote directly for the party-list, but in other systems voters may vote for directly individuals candidates within or across party lists, besides or instead of voting directly for parties.
Block plurality voting is a winner-take-all method for multi-winner elections. Each voter may cast as many votes as the number of seats to be filled. The usual result when the candidates divide into parties is that the most popular party in the district sees its full slate of candidates elected.
Electoral districts go by different names depending on the country and the office being elected.
There are five types of elections in the United Kingdom: elections to the House of Commons of the United Kingdom, elections to devolved parliaments and assemblies, local elections, mayoral elections, and police and crime commissioner elections. Within each of those categories, there may also be by-elections. Elections are held on Election Day, which is conventionally a Thursday, and under the provisions of the Dissolution and Calling of Parliament Act 2022 the timing of general elections can be held at the discretion of the prime minister during any five-year period. All other types of elections are held after fixed periods, though early elections to the devolved assemblies and parliaments can occur in certain situations. The five electoral systems used are: the single member plurality system (first-past-the-post), the multi-member plurality, the single transferable vote, the additional member system, and the supplementary vote.
An electoral 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.
A winner-take-all electoral system is one where a voting bloc can win all seats in a legislature or electoral district, denying representation to any political minorities. Such systems are used in many major democracies. Such systems are sometimes called "majoritarian representation", though this term is a misnomer, as most such systems do not always elect majority preferred candidates and do not always produce winners who received majority of votes cast in the district, and they allow parties to take a majority of seats in the chamber with just a minority of the vote.
Dual-member proportional representation (DMP), also known as dual-member mixed proportional, is an electoral system designed to produce proportional election results across a region by electing two representatives in each of the region’s districts. The first seat in every district is awarded to the candidate who receives the most votes, similar to first-past-the-post voting (FPTP). The second seat is awarded to one of the remaining district candidates so that proportionality is achieved across the region, using a calculation that aims to award parties their seats in the districts where they had their strongest performances.
