Plurality voting

Plurality voting refers to electoral systems in which the candidates in an electoral district who poll more than any other (that is, receive a plurality) are elected.[1]

Under single-winner plurality voting, and in systems based on single-member districts, plurality voting is called single member [district] plurality (SMP),[2][3] which is widely known as "first-past-the-post". In SMP/FPTP the leading candidate, whether or not they have a majority of votes, is elected.[4]

There are several versions of plurality voting for multi-member district.[5] The system that elects multiple winners at once with the plurality rule and where each voter casts multiple X votes in a multi-seat district is referred to as plurality block voting. A semi-proportional system that elects multiple winners elected at once with the plurality rule and where each voter casts just one vote in a multi-seat district is known as single non-transferable voting.

Plurality voting is widely used throughout the English-speaking world as a result of its spread by the British Empire, including in most of the United States. Outside of the English-speaking world, it is less popular[citation needed] than its close relatives in the runoff family of methods. Overall, more countries in the world use a form of proportional representation than use plurality or a form of runoff.[6]
