Proportional representation (PR) is a democratic electoral system designed to ensure that the distribution of seats reflects the overall proportion of votes received by each political party.
Unlike the predominant winner-takes-all system in the United States, PR seeks to eliminate the problem of wasted votes and better represent diverse viewpoints.
PR systems come in various forms, such as the list PR, single transferable vote (STV), and mixed-member proportional (MMP), each tailored to the specific needs of a nation's political landscape.
