Definition: A plurality electoral system is an electoral system in which candidates can win seats without receiving a majority of the votes. Most plurality electoral systems use single-member electoral districts, whose boundaries must be changed from time to time to remain relatively equal in population.
In a plurality electoral system, the candidate receiving the highest number of votes wins, but does not have to have a majority.
There are five main types of plurality electoral systems:
- first past the post
- single non-transferable vote
- block vote
- limited vote
- approval voting
