Dual-member proportional representationDual-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.
Alternative vote plusThe alternative vote plus (AV+), or alternative vote top-up, is a semi-proportional voting system. AV+ was devised by the 1998 Jenkins Commission which first proposed the idea as a system that could be used for elections to the Parliament of the United Kingdom. As the name suggests, AV+ is an additional member system which works in two parts: the 'AV' part and the 'plus' part. As in the alternative vote system, candidates are ranked numerically in order of preference.

Leveling seatLeveling seats (tillægsmandat, utjämningsmandat, utjevningsmandater, jöfnunarsæti, Ausgleichsmandat), commonly known also as adjustment seats, are an election mechanism employed for many years by all Nordic countries (except Finland) in elections for their national legislatures. In 2013, Germany also introduced national leveling seats for their national parliament, the Bundestag. The electoral reform in Germany 2023 removed the leveling seats, and replaced with Zweitstimmendeckung.
Electoral reformElectoral reform is a change in electoral systems which alters how public desires are expressed in election results. Reforms can include changes to: Voting systems, such as proportional representation, a two-round system (runoff voting), instant-runoff voting (alternative voting, ranked-choice voting, or preferential voting), Instant Round Robin Voting called Condorcet Voting, range voting, approval voting, citizen initiatives and referendums and recall elections.
Double simultaneous voteDouble simultaneous vote (DSV) is an electoral system in which multiple offices – such as the president and members of a legislature – are elected through a single vote cast for a party. It can be combined with other electoral systems; in Uruguay DSV is used to elect the president and members of the Senate and Chamber of Representatives, with the presidential election also using the two-round system; if no party/presidential candidate receives a majority of the vote, a second round is held for the presidential election.

Mixed-member majoritarian representationMixed member majoritarian representation (MMM) is type of a mixed electoral system combining majoritarian and proportional methods, where the disproportional results of the majoritarian side of the system prevail over the proportional component. Mixed member majoritarian systems are therefore also as a type of semi-proportional representation, and are usually contrasted with mixed-member proportional representation (MMP) which aims to provide proportional representation via additional compensation ("top-up") seats.
