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 – not just a bare plurality or (exclusively) the majority – and that the system produces mixed, balanced representation reflecting how votes are cast.
The two-round system (TRS), also known as runoff voting, second ballot, or ballotage, is a voting method used to elect a single candidate, where voters cast a single vote for their preferred candidate. It generally ensures a majoritarian result, not a simple-plurality result as under first past the post. Under the two-round election system, the election process usually proceeds to a second round only if in the first round no candidate received an absolute majority of votes cast, or some other lower prescribed percentage. Under the two-round system, usually only the two candidates who received the most votes in the first round, or only those candidates who received above a prescribed proportion of the votes, are candidates in the second round. Other candidates are excluded from the second round.
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.
The House of Representatives is the lower house of the bicameral Parliament of Australia, the upper house being the Senate. Its composition and powers are set down in Chapter I of the Constitution of Australia.
Albania is a unitary parliamentary constitutional republic, in which the president of Albania is the head of state and the prime minister of Albania is the head of government in a multi-party system. The executive power is exercised by the Government and the prime minister with its Cabinet. Legislative power is vested in the Parliament of Albania. The judiciary is independent of the executive and the legislature. The political system of Albania is laid out in the 1998 constitution. The Parliament adopted the current constitution on 28 November 1998. Historically Albania has had many constitutions. Initially constituted as a monarchy in 1913, Albania became briefly a republic in 1925, and then a authoritarian monarchy in 1928. In 1939 Albania was invaded by Fascist Italian forces, imposing a puppet state, and later occupied by Nazi German forces. Following the partisan liberation from the Nazis in 1944 a provisional government was formed, which by 1946 had transformed into a communist one-party state. In March 1991 democracy was restored with multi-party elections.
The electoral system of Australia 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.
The Victorian Legislative Council (VLC) is the upper house of the bicameral Parliament of Victoria, Australia, the lower house being the Legislative Assembly. Both houses sit at Parliament House in Spring Street, Melbourne. The Legislative Council serves as a house of review, in a similar fashion to its federal counterpart, the Australian Senate. Although, it is possible for legislation to be first introduced in the Council, most bills receive their first hearing in the Legislative Assembly.
An electoral district, also known as an election district, legislative district, voting district, constituency, riding, ward, division, electorate, or (election) precinct, is a subdivision of a larger state created to provide its population with representation in the larger state's constituency. 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.
Elections in Chile are held nationwide, including the presidency, parliament, regional offices, and municipal positions. Chilean citizens and foreign residents with legal residency of at least five years, who are 18 years or older on election day, are eligible to vote. Previously, voting was voluntary, but since 2023, it has become compulsory.
France is a unitary semi-presidential republic with a bicameral legislature. Public officials in the legislative and executive branches are either elected by the citizens or appointed by elected officials. Referenda may also be called to consult the French citizenry directly on a particular question, especially one which concerns amendment to the Constitution.
Though Afghanistan has had democratic elections throughout the 20th century, the electoral institutions have varied as changes in the political regime have disrupted political continuity. Elections were last held under the Islamic Republic of Afghanistan, which was deposed by the Taliban in August 2021. The Taliban dissolved the Elections Commission in December 2021. In May 2022, when asked if the Taliban would hold elections, First Deputy Leader Sirajuddin Haqqani said the question was "premature". All political parties have been banned since August 2023.
Elections in Lithuania are held to select members of the parliament, the president, members of the municipal councils and mayors, as well as delegates to the European Parliament. Lithuanian citizens can also vote in mandatory or consultative referendums.
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.
Instant-runoff voting (IRV) is a voting method used in single-seat elections with more than two candidates. Instead of voting only for a single candidate, voters in IRV elections can rank the candidates in order of preference. Ballots are initially counted for each elector's top choice, losing candidates are eliminated, and ballots for losing candidates are redistributed until one candidate is the top remaining choice of a majority of the voters. When the field is reduced to two, it has become an "instant runoff" that allows a comparison of the top two candidates head-to-head.
Instant-runoff voting (IRV), also known as plurality with elimination,plurality loser, or Hare RCV, is a ranked-choice voting system that modifies plurality by repeatedly eliminating the last-place winner until only one candidate is left. In the United Kingdom, it is generally called the alternative vote (AV). In the United States, IRV is often referred to as ranked-choice voting (RCV), by way of conflation with ranked voting systems in general.
Electoral reform is a change in electoral systems which alters how public desires are expressed in election results.
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.
