In proportional representation systems, parties gain seats in the legislature in proportion to the number of votes they receive in elections. This differs from winner-takes-all systems, where only the candidate with the most votes wins. Various methods exist for implementing proportional representation, including party-list systems, single transferable vote, and mixed-member proportional systems. Proportional representation is often praised for increasing the diversity of political representation and improving voter satisfaction, as smaller parties have a better chance to gain seats.
