District that elects only one representative.

A geographic district from which a single member is elected by a majority or plurality of the popular vote to represent it in a legislative body.

The current arrangement for electing national and state legislators in the United States in which one candidate is elected in each legislative district; the winner is the candidate with the most votes. The single-member system allows only one party to win in any given district. This is directly opposite to the more common proportional system, in which much larger districts are used and several members are elected at one time based on the proportion of votes their parties receive.
