In contrast to multi-member districts, single-member districts elect only one representative per geographic constituency.
Proportional Representation (PR): Proportional representation is an electoral system used in some multi-member district systems, aiming to allocate seats proportionally based on the percentage of votes received by each political party or group.
List System: The list system is a type of proportional representation used in multi-member district systems, where voters choose from pre-determined lists of candidates presented by political parties or groups.
