A majority is a subset of a set consisting of more than half of the set’s elements. This can be compared to a plurality, which is a subset larger than any other subset considered; i.e. a plurality is not necessarily a majority as the largest subset considered may consist of less than half the set’s elements. 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. A majority may be called a simple majority to contrast with other types of majority: an overall majority, in parliamentary systems, is the difference of legislators between the government and its opposition; an absolute majority is a majority of all electors, not just those who voted; and a supermajority is a stronger majority than a simple majority.
