Scrutin majoritaire uninominalLe scrutin uninominal, ou scrutin uninominal majoritaire, est un système électoral dans lequel une seule personne est élue lors d'un scrutin. Il peut être utilisé soit pour pourvoir une fonction unique, soit pour élire une assemblée, en divisant le territoire en autant de circonscriptions que de sièges à pourvoir. Il s'agit d'un scrutin majoritaire. Il s'oppose au scrutin plurinominal. Il existe plusieurs types de scrutin uninominal.
Overhang seatOverhang seats are constituency seats won in an election under the traditional mixed member proportional (MMP) system (as it originated in Germany), when a party's share of the nationwide votes would entitle it to fewer seats than the number of individual constituencies won. The electoral reform in Germany removed the overhang seats, and replaced with Zweitstimmendeckung. Under MMP, a party is entitled to a number of seats based on its share of the total vote.
ScorporoScorporo (ˈskɔrporo, parceling out) is a partially compensatory, mixed-member majoritarian electoral system, sometimes referred to as a negative vote transfer system (NVT) whereby a portion of members are elected in single-member districts (SMDs) and a portion are elected from a list. It may be fully defined as a parallel voting system which excludes a portion (up to 100%) of the SMD winners' votes in electing the proportional tier, to result in a more proportional outcome.
FairVoteFairVote, formerly the Center for Voting and Democracy, is a 501(c)(3) organization that advocates electoral reform in the United States. Founded in 1992 as Citizens for Proportional Representation to support the implementation of proportional representation in American elections, the organization in 1993 became the Center for Voting and Democracy and in 2004 changed its name to FairVote to reflect its support of such proposals as instant-runoff voting (IRV), for single and multi-winner elections, a national popular vote for president, a right-to-vote amendment to the Constitution, and universal voter registration.
Electoral allianceAn electoral alliance (also known as a bipartisan electoral agreement, electoral pact, electoral agreement, electoral coalition or electoral bloc) is an association of political parties or individuals that exists solely to stand in elections. Each of the parties within the alliance has its own policies but chooses temporarily to put aside differences in favour of common goals and ideology in order to pool their voters' support and get elected.
Prime majoritaireLa prime majoritaire est une modalité des systèmes électoraux mixtes dans laquelle un nombre déterminé de sièges est attribué à la liste ayant obtenu le plus de voix. Les autres sièges sont distribués entre les listes en fonction du nombre de voix obtenues. La prime majoritaire vise à favoriser la constitution d'une majorité en atténuant la représentation proportionnelle. Elle est utilisée en Arménie, en Grèce et à Saint-Marin. Elle est également utilisée dans les élections municipales et régionales françaises, ainsi que dans trois assemblées régionales en Argentine.
Highest averages methodA highest-averages method, also called a divisor method, is a class of methods for allocating seats in a parliament among agents such as political parties or federal states. A divisor method is an iterative method: at each iteration, the number of votes of each party is divided by its divisor, which is a function of the number of seats (initially 0) currently allocated to that party. The next seat is allocated to the party whose resulting ratio is largest.

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.
Sequential proportional approval votingSequential proportional approval voting (SPAV) or reweighted approval voting (RAV) is an electoral system that extends the concept of approval voting to a multiple winner election. It is a simplified version of proportional approval voting. Proposed by Danish statistician Thorvald N. Thiele in the early 1900s, it was used (with adaptations for party lists) in Sweden for a short period from 1909-1921, and was replaced by a cruder "party-list" style system as it was easier to calculate.
