Majority electoral systems can, and do, produce election outcomes that are just as disproportional as plurality electoral systems with regard to the ratio of seats to votes. This is not surprising, given that both systems rely almost exclusively on single-member districts. The district delimitation process in a majority system is, therefore, just as important as it is in a plurality electoral system.
Plurality voting is distinguished from a majoritarian electoral system, in which, to win, a candidate must receive an absolute majority of votes, i.e., more votes than all other candidates combined. Both systems may use single-member or multi-member constituencies.
Mixed member proportional representation (MMP), also called the additional member system (AMS), is a two-tier mixed electoral system combining a non-proportional plurality/majoritarian election and a compensatory regional or national party list PR election.
