A majority, also known as a simple majority in the U.S., is a subset of a group consisting of more than half of the group. This should not be confused with a plurality, which is a subset having the largest number of parts. A plurality is not necessarily a majority, as the largest subset may be less than half of the entire group. In British English, majority and plurality are often used as synonyms; it can also refer to the margin of vote separating the first-place finisher from the second-place finisher, so that a candidate who wins by 1000 votes may be said to have received "a majority of 1000 votes". The term "overall majority" is used in British English to refer to the difference between the number of votes received by the winner and the combined votes cast for all other candidates. The term "absolute majority" is used to indicate more than fifty percent of the vote.
For example, in a hypothetical group of 40 athletes there are:
- 15 association football players
- 10 sprinters
- 9 marathon runners
- 6 table tennis players
In this group, a majority would consist of more than half the total number of athletes, or 21 athletes. The group of all ball sport players together (15 football players + 6 table tennis players = 21) comprise a majority. However, football players, 15 in number, comprise a plurality, not a majority. In British English usage, football players would be described as having a majority of 5 (15 - 10) over sprinters, no individual sport has an absolute majority or an overall majority, and ball players have an overall majority of 2 (21 - 19) over the other sports.
