International Examples of Mixed-Member Proportional (MMP) Systems

Mixed-Member Proportional (MMP) voting systems are used in various countries and regions around the world. This page provides examples of how MMP has been implemented in different contexts.

New Zealand

New Zealand adopted MMP in the 1990s, following a public referendum in 1993. Some notable features of its implementation include:

• Two Votes: Voters cast one vote for a local electorate candidate and another for a political party.
• Mixed-Member System: The Parliament includes both electorate MPs and list MPs.
• Threshold: A party must win at least one electorate seat or 5% of the party vote to gain list seats.
• Coalition Governments: The system has often resulted in coalition governments that may reflect a broader range of views.
• Electoral Commission: An independent electoral commission is responsible for implementing and administering the system.

Germany

Germany's electoral system, often referred to as "Personalized Proportional Representation", is a well-established example of a mixed-member system. Its key elements include:

• Two Votes: Voters cast one vote for a constituency candidate, and one for a party list.
• Mixed-Member System: The Bundestag includes both directly elected constituency members and members elected from party lists.
• No Threshold for Direct Seats: There is no vote threshold to win a direct seat. However, a party must win at least three direct seats, or achieve at least 5% of the party vote to be awarded seats from a party list.
• Proportionality: The total seats each party gains aims to be proportional to its share of the party vote.
• Stable Governance: The system has been credited with providing stable governance while ensuring representation of diverse political interests.

Other Examples

Several other countries and regions use systems based on mixed-member proportional representation. These include:

• Parts of Latin America: Countries like Mexico and Bolivia use forms of MMP at a national level.
• Parts of Europe: Some regions in Europe have adopted systems which are similar to MMP.
• Africa: Several African nations also employ elements of MMP in their electoral processes.

Key Observations

• Variety in Design: MMP is implemented in a variety of ways, reflecting unique national circumstances.
• Focus on Proportionality: Despite variations, each system aims to achieve a more proportional outcome than purely majoritarian systems.
• Influence on Political Culture: The systems influence the way governments are formed and the types of political cooperation that take place.
