# Majority

A majority, also called a simple majority to distinguish it from similar terms, is the greater part, or more than half, of the total. It is also a plurality, which is defined as one group being greater than any other in the set. It is a subset of a set consisting of more than half of the set's elements. For example, if a group consists of 20 individuals, a majority would be 11 or more individuals, while having 10 or fewer individuals would not constitute a majority. "Majority" can be used to specify the voting requirement, as in a "majority vote", which means more than half of the votes cast.
A majority can be compared to a plurality, which is a subset larger than any other subset but not larger than all other subsets combined. For example, if there is a group with 20 members which is divided into subgroups with 9, 6, and 5 members, then the 9-member group would be the plurality. A plurality is not necessarily a majority as the largest subset considered may consist of less than half the set's elements. This can occur when there are three or more possible choices.
In British English the term "majority" is also alternatively used to refer to the winning margin, i.e., the number of votes separating the first-place finisher from the second-place finisher. Other related terms containing the word "majority" have their own meanings, which may sometimes be inconsistent in usage.

## Majority vote

In parliamentary procedure, the term "majority" simply means "more than half." As it relates to a vote, a majority vote is more than half of the votes cast. Abstentions or blanks are excluded in calculating a majority vote. Also, the totals do not include votes cast by someone not entitled to vote or improper multiple votes by a single member.
Depending on the parliamentary authority used, there may be a difference in the total that is used to calculate a majority vote due to "illegal votes". Illegal votes are votes which are cast for unidentifiable or ineligible candidates or choices. In this definition, "illegal" refers to the choices made on the ballot and does not refer to the persons who cast the votes.
In Robert's Rules of Order Newly Revised, illegal votes are counted as votes cast, but are not credited to any candidate. In The Standard Code of Parliamentary Procedure, illegal votes are not included in the total and a majority vote is defined as being more than half of all eligible votes cast. The issue of "illegal votes" does not exist when only two options are possible, such as when a majority vote is required to adopt a proposal. In this context, a majority vote is more "yes" votes than "no" votes.
A majority vote is not the same as a vote of a "majority of the members present" or a vote of a "majority of the entire membership".

## Examples

For example, assume that votes are cast for three people for an office: Alice, Bob, and Carol.

### Scenario 1

In Scenario 1, Alice received a majority vote. There were 20 votes cast and Alice received more than half of them.

### Scenario 2

In Scenario 2, assume all three candidates are eligible. In this case, no one received a majority vote. This example also illustrates that half the votes cast is not a majority vote.

### Scenario 3

In Scenario 3, assume that Alice and Bob are eligible candidates, but Carol is not. Using Robert's Rules of Order, no one received a majority vote, which is the same as Scenario 2. In this case, the 4 votes for Carol are counted in the total, but are not credited to Carol. However, using The Standard Code, Alice received a majority vote since only votes for eligible candidates are counted using this book. In this case, there are 16 votes for eligible candidates and Alice received more than half of those 16 votes.

### Comparison to plurality

In all three scenarios, Alice received a plurality, or the most votes among the candidates. However, only in Scenario 1 did Alice receive a majority vote using Robert's Rules of Order.

## Related terms

Other related terms containing the word "majority" have their own meanings, which may sometimes be inconsistent in usage.
A majority may sometimes be called a "simple majority" to contrast with other terms using "majority". A "simple majority" may also mean a "relative majority", or a plurality. These two definitions would conflict when a "simple majority" is not a "majority".
An "absolute majority" may mean a majority of all electors, not just those who voted. This usage would be equivalent to a "majority of the entire membership". However, the definition for "absolute majority" is not consistent, as it could also mean the same as "majority" or "simple majority". The meanings for "absolute majority" and "simple majority" would have to be determined from the context in which these terms are used.
A "supermajority", or a "qualified majority", is a specified higher threshold than one half. A common use of a supermajority is a "two-thirds vote", which is sometimes referred to as a "two-thirds majority".
In parliamentary systems, an "overall majority" is the difference of legislators between the government and its opposition. In this context, the term "majority" could be also alternatively used to refer to the winning margin, i.e. the number of votes separating the first-place finisher from the second-place finisher.
A "double majority" is a voting system which requires a majority of votes according to two separate criteria.

## Temporary majority

A temporary majority exists when the positions of the members present and voting in a meeting of a deliberative assembly on a subject are not representative of the membership as a whole. Parliamentary procedure contains some provisions designed to protect against a temporary majority violating the rights of absentees. For instance, previous notice is required to rescind, repeal or annul or amend something previously adopted by a majority vote; if previous notice has not been given, a two-thirds vote is required. However, in this and many other cases, previous notice is not required if a majority of the entire membership votes in favor, because that indicates that it is clearly not a temporary majority. Another protection against a decision being made by a temporary majority is the motion to reconsider and enter on the minutes, by which two members can suspend action on a measure until it is called up at a meeting on another day.

## Application in other voting requirements

"Majority" could be specified with respect to the voting body.

### "Majority of the entire membership" and "majority of the fixed membership"

A "majority of the entire membership" means more than half of all the members of a body. A "majority of the fixed membership" means more than half of all the seats of a body. A majority of the entire membership is different from a majority of the fixed membership when there are vacancies.
For example, say a board has 12 seats. If the board has the maximum number of members, or 12 members, a majority of the entire membership and a majority of the fixed membership would both be 7 members. However, if there are two vacancies, then a majority of the entire membership would be 6 members, but a majority of the fixed membership would still be 7 members.

### "Majority of the members present"

A "majority of the members present" means more than half of the members at the meeting. If 30 members were at a meeting, a majority of the members present would be 16. In any situation which specifies such a requirement for a vote, an abstention would have the same effect as a "no" vote.
A vote of a "majority of the members present" is not the same as a "majority vote". When unqualified, a "majority vote" is taken to mean more than half of the votes cast. If 30 members were at a meeting, but only 20 votes were cast, a majority vote would be 11 votes.

## Erroneous definitions

Erroneous definitions of majority include "50% +1" and "51%".
For example, say a board has 7 members. A majority would be 4. If "50% +1" is used, the number calculated would be 3.5+1, and thus a majority may be mistaken as 4.5, and by using Swedish rounding would be rounded up to 5. This confusion would exist for all odd numbers using the erroneous definition of "50%+1", though this can be fixed by remembering to always round down, in which case both odd and even numbers would work out correctly.
In another example, say a convention has 1000 delegates. Using the erroneous definition of 51% would result in a majority being mistaken as 510 instead of 501. The same logic applies for 50.1%, 50.01%, 50.001%, etc.
