Party List Proportional Representation Calculator

Introduction & Importance

Party list proportional representation (PR) is a voting system that aims to ensure that the number of seats won by each party in a legislature reflects the number of votes received by that party. It’s important because it promotes fairness, encourages diverse representation, and can lead to more stable governments.
