The document discusses different electoral systems and their characteristics. It compares the single-member-district plurality (SMDP) system and the proportional representation (PR) system. The SMDP system favors large parties and hurts small ones, while the PR system provides proportional representation in the legislative body based on a party's electoral strength. It also discusses conditions like small district numbers that can cause the SMDP system to disadvantage small parties. Referendums allow direct public voting on policy decisions. Voter turnout varies significantly between countries and different demographic groups.
