plurality

n. numerousness, variability; majority of voices in a vote

A plurality, relative majority or simple majority is the largest share of something, which may or may not be considered an absolute majority, i.e. it is the largest group/category, but is not necessarily a majority (more than half). In United States usage, a simple majority does not include abstentions or absent members. It is more strict than a plurality vote, but less strict than an absolute majority vote. The plurality voting system, also known as "First past the post", elects the candidate who is the stated first choice of the plurality of voters.
