Majoritarian and Proportional Representation Electoral Systems
Electoral systems determine how the votes cast by citizens are translated into political mandates. They therefore have a significant influence on the composition of a parliament, which parties are represented, and how governments are formed. The two fundamental principles are the majoritarian electoral system and the proportional representation system.
Under a majoritarian system, the main question is which candidate in a constituency receives the most votes or the required majority. Under proportional representation, the focus is instead on the relative strength of the parties. If a party receives, for example, 30 percent of the relevant votes, it should generally receive approximately 30 percent of the seats in parliament.
Germany uses neither a purely majoritarian system nor a purely proportional system for elections to the German Bundestag. The Bundestag electoral system is a form of personalized proportional representation. It combines the election of individual candidates in constituencies with proportional allocation of seats based on party votes. Since the electoral reform first applied in the 2025 federal election, the importance of the second vote for the composition of the Bundestag has become particularly significant.
1. What Is an Electoral System?
An electoral system establishes how votes are converted into political mandates. This includes, among other things, the division of a country into constituencies, the number of votes each voter has, whether voters elect individual candidates or parties, how seats are allocated, and whether electoral thresholds apply.
The fundamental distinction between majoritarian and proportional systems concerns the objective that takes priority when votes are converted into seats: should the winner in individual constituencies determine representation, or should parliament reflect the overall political distribution of voters as accurately as possible?
No electoral system is completely neutral. Each system places greater emphasis on certain political objectives. A majoritarian system can favor larger parties and clear majorities, while proportional representation generally allows a broader range of political parties to be represented.
2. The Majoritarian Electoral System
Under a majoritarian electoral system, a country or region is divided into constituencies. Candidates compete against one another in each constituency. The mandate generally goes to the candidate who obtains the required majority.
Under first-past-the-post or plurality voting, it is sufficient for a candidate to receive more votes than any other candidate. An absolute majority of more than 50 percent is not required.
A simple example:
| Candidate | Share of Votes |
|---|---|
| A | 42% |
| B | 33% |
| C | 15% |
| D | 10% |
Candidate A wins the constituency, even though 58 percent of voters chose someone else. The votes cast for the losing candidates do not produce separate mandates in that constituency.
Another variant is the absolute majority system. Here, a candidate must receive more than half of the votes. If no candidate achieves this majority in the first round, a second round may be held. A well-known example is the election of the French National Assembly.
Advantages of Majoritarian Systems
A commonly cited advantage of majoritarian voting is the clear relationship between a constituency and its elected representative. Voters know directly which person has won their constituency. This gives the representative a strong regional connection.
Plurality voting is also relatively easy to understand: the candidate with the most votes wins. There is no need for a complex nationwide calculation to distribute parliamentary seats according to party vote shares.
Another possible advantage is that majoritarian systems tend to favor larger parties. As a result, parliament may consist of relatively few parties. If one party wins a large number of constituencies, it may be able to form a government on its own, without requiring a coalition.
Disadvantages of Majoritarian Systems
The most important criticism concerns the number of votes that have no direct effect on the distribution of seats. A voter who supports a losing candidate does not, under a pure majoritarian system, contribute to the election of another candidate from that constituency.
In addition, vote shares and seat shares can differ considerably. A party might receive 40 percent of the votes nationwide but win 60 percent of the constituencies because its support is distributed particularly favorably.
Conversely, a smaller party can receive a substantial share of the vote but win relatively few seats. This can be particularly significant for parties whose supporters are evenly distributed across a country and who therefore finish narrowly behind another party in many constituencies.
3. Proportional Representation
Under proportional representation, the focus is not on winning individual constituencies but on distributing parliamentary seats in proportion to the strength of the parties. Seats are generally allocated according to each party's share of the vote.
A simplified example of a parliament with 100 seats:
| Party | Share of Votes | Seats |
|---|---|---|
| A | 40% | 40 |
| B | 30% | 30 |
| C | 20% | 20 |
| D | 10% | 10 |
In an idealized proportional system, the distribution of seats therefore corresponds directly to the distribution of votes. In practice, however, parliamentary seats cannot be divided into fractions. Mathematical methods are therefore used to convert vote totals into whole seats.
Advantages of Proportional Representation
The main advantage is that proportional representation provides a relatively accurate reflection of voters' preferences. Votes for a party generally contribute to its parliamentary representation even if that party does not win individual constituencies.
This gives smaller and medium-sized parties better opportunities to gain parliamentary representation. A proportional system can therefore represent a broader range of political movements and social interests.
Proportional representation can also reduce the number of votes that have no influence on the distribution of seats. An additional vote for a party can increase its share of parliamentary seats, provided that the party meets any applicable requirements for parliamentary representation.
Disadvantages of Proportional Representation
Greater proportionality can result in a larger number of parties being represented in parliament. This can make it more difficult to form a government with a parliamentary majority.
In such cases, coalition governments become necessary. Coalitions can bring together different political interests and encourage compromise. At the same time, they can make it less straightforward to attribute political decisions to a single party.
In list-based systems, parties also play an especially important role in selecting and ordering candidates. With closed lists, voters cannot alter the order of candidates on the party list.
4. Majoritarian and Proportional Systems Compared
| Feature | Majoritarian System | Proportional Representation |
|---|---|---|
| Decisive principle | Winning the constituency | Party vote share |
| Main focus | Individual candidates | Parties and lists |
| Vote-seat relationship | Can differ substantially | Generally proportional |
| Smaller parties | Generally disadvantaged | Generally favored |
| Regional representation | Very strong | Depends on the specific system |
| Number of parties | Tends to be lower | Tends to be higher |
| Coalition governments | Potentially less frequent | More frequent |
5. The German Bundestag Electoral System
The German electoral system for the Bundestag is based on personalized proportional representation. It therefore combines elements of majoritarian and proportional voting.
Since the electoral reform, the Bundestag has a statutory size of 630 members. Germany is divided into 299 constituencies for Bundestag elections.
Each voter has two votes in a Bundestag election: the first vote and the second vote.
The First Vote
The first vote is cast for a candidate in the voter's constituency. In principle, the candidate receiving the most first votes wins the constituency.
The first vote therefore has a clear majoritarian element. Since the 2025 federal election, however, winning a constituency no longer automatically results in a Bundestag seat.
This is due to the principle known as second-vote coverage. A constituency victory by a party must be covered by the number of seats that the party is entitled to based on its second-vote result.
The Second Vote
The second vote is cast for a party's state list. It is decisive for the proportional composition of the Bundestag.
In simplified terms, the second-vote result determines how large a party's share of the Bundestag should be. Successful constituency candidates are then taken into account within that party's seat allocation.
This is the key difference from a classic majoritarian system: winning a constituency alone no longer guarantees a parliamentary seat.
6. Why Was the Bundestag Electoral System Changed?
One major reason for the electoral reform was the increasing size of the Bundestag. Under the previous system, so-called overhang seats could arise. If a party won more constituencies than the number of seats to which it was entitled based on its second-vote share, it could receive additional seats.
To restore the proportional balance between the parties, additional leveling seats were then awarded. As a result, the Bundestag could become considerably larger than its intended size.
Following the 2021 federal election, for example, the Bundestag had 736 members. The reform was intended to make the size of the Bundestag more predictable and manageable.
The new electoral law therefore provides for a fixed size of 630 seats. At the same time, it places the second vote more clearly at the center of the proportional allocation of seats.
7. Second-Vote Coverage Explained
Suppose a party is entitled to ten seats in a particular state based on its second-vote result.
At the same time, the party wins twelve constituencies. Under the current electoral law, all twelve constituency winners cannot automatically enter the Bundestag. The party's seat allocation amounts to only ten seats.
The successful constituency candidates are therefore considered according to their first-vote results. Only as many constituency winners can receive a mandate as are covered by the party's second-vote allocation.
This prevents a party from receiving more seats through constituency victories than its proportional share based on second votes would justify.
8. The Five-Percent Electoral Threshold
The Bundestag electoral system also contains an electoral threshold. As a general rule, a party must receive at least five percent of the relevant second votes to participate in the allocation of seats.
The purpose of this threshold is to prevent excessive fragmentation of parliament. Without such a threshold, parties could potentially enter parliament with very small shares of the vote.
The five-percent threshold is nevertheless a limitation on fully proportional representation. A party could receive, for example, just under four percent of the vote and still fail to receive seats corresponding to its share of the electorate.
The Basic-Mandate Clause
German electoral law also contains a special provision for parties that remain below five percent but win several constituencies. The so-called basic-mandate clause can allow such a party to participate in the proportional distribution of seats.
A well-known example is the 2021 federal election. The Left Party (Die Linke) remained below five percent of the second vote but won three constituencies and was therefore included in the allocation of seats.
9. Is the First Vote More Important Than the Second Vote?
The terminology can lead to a misunderstanding. The first vote is not simply the "more important" vote because it is listed first.
The second vote is decisive for the composition of the Bundestag. It generally determines the proportional share of seats allocated to each party.
The first vote primarily serves the purposes of personalization and regional representation. It determines which candidate receives the most votes in a constituency and can therefore be given priority within the party's seat allocation, subject to the second-vote coverage rule.
10. Proportional Representation in State Elections
Proportional representation also plays a central role in elections to Germany's state parliaments, the Landtage. However, the individual states have different electoral systems.
Many states use variants of personalized proportional representation. These systems often include constituency and party-list votes or comparable elements.
The details differ considerably, however. It is therefore not correct to say that every state election functions exactly like a Bundestag election.
Some states use distinct models. Baden-Württemberg, for example, has a special electoral system, while Hamburg and Bremen also use systems that differ from the classic Bundestag model.
11. European Parliament Elections in Germany
The election of German members of the European Parliament is based on proportional representation. Voters have one vote and choose a party list.
Unlike Bundestag elections, Germany currently has no five-percent electoral threshold for European Parliament elections. Smaller parties can therefore win seats if their share of the vote is sufficient.
The European election is therefore an example of an election in which proportional representation is more strongly emphasized than the direct election of individual representatives in constituencies.
12. Local Elections
Local elections are particularly diverse. Electoral rules are established by the individual German states and therefore differ from one state to another.
Many states use proportional systems that give voters additional opportunities to select individual candidates.
These include mechanisms such as cumulation and panachage. Cumulation allows voters to concentrate several votes on a particular candidate. Panachage allows voters to distribute votes among candidates from different parties or lists.
Local elections can therefore differ considerably from Bundestag elections.
13. The Bundesrat Is Not Elected by Majoritarian or Proportional Vote
The Bundesrat is a special case. Its members are not directly elected by the public.
The Bundesrat consists of members of the state governments. The states appoint their representatives and can recall them. The Bundesrat is therefore an institution representing the federal states rather than a directly elected popular chamber like the Bundestag.
14. Majoritarian and Proportional Representation: An Example
The difference can be illustrated particularly clearly using a fictional country with 100 constituencies.
Suppose Party A receives 40 percent of the nationwide vote, Party B 35 percent, Party C 15 percent, and Party D 10 percent.
Under an idealized proportional system, the distribution of seats would be roughly:
- Party A: 40 seats
- Party B: 35 seats
- Party C: 15 seats
- Party D: 10 seats
Under a plurality system, however, Party A might win 55 constituencies, Party B 40, and Party C five. Party D would receive no seats despite obtaining ten percent of the vote.
The example demonstrates a key difference: under majoritarian voting, the geographical distribution of votes is important. Under proportional representation, the overall vote share is much more decisive.
15. Which Electoral System Is Better?
There is no universally objective answer to whether majoritarian or proportional representation is "better." The two systems prioritize different political objectives.
Those who prioritize clear majorities, a strong regional relationship between representatives and constituencies, and relatively straightforward decision-making may see advantages in majoritarian systems.
Those who prioritize accurate representation of vote shares, political diversity, and stronger representation for smaller parties may prefer proportional representation.
The central political question is therefore not simply "Which system is more democratic?" but rather: Which form of democratic representation should receive greater weight?
16. The German Model as a Compromise
Germany's Bundestag electoral system attempts to combine several objectives. Constituencies provide a personal and regional element, while second votes ensure proportional representation of the parties.
The five-percent threshold is intended to prevent excessive fragmentation of parliament. The basic-mandate clause can nevertheless take account of parties that have strong support in several constituencies despite receiving a relatively small nationwide share of second votes.
The electoral reform has also limited the size of the Bundestag to 630 seats. The second-vote coverage rule ensures that constituency victories do not automatically result in a larger parliament or a significant departure from the proportional distribution determined by second votes.
17. Conclusion
Majoritarian and proportional representation systems pursue different objectives. Under a majoritarian system, the success of individual candidates in constituencies is decisive. Such systems can produce clear majorities and establish a strong relationship between representatives and their constituencies. At the same time, many votes can have no direct effect on the distribution of seats, and seat shares can differ substantially from vote shares.
Proportional representation, by contrast, seeks to reflect the political balance of the electorate as accurately as possible. This gives smaller parties better opportunities for parliamentary representation. At the same time, a larger number of parties can make coalition governments more likely.
Germany uses personalized proportional representation for elections to the Bundestag. The first vote is used to elect a candidate in a constituency, while the second vote is decisive for the proportional composition of the Bundestag.
Since the 2025 federal election, the reformed electoral law has been in force. The Bundestag has a statutory size of 630 members. Winning a constituency no longer automatically guarantees a seat; the constituency victory must be covered by the party's second-vote allocation.
It is therefore inaccurate to describe Germany as having a purely majoritarian electoral system. It would be equally simplistic to describe the Bundestag system as pure proportional representation. The more precise description is personalized proportional representation with constituency-based elements.
State and local elections are governed by different rules depending on the German state. European Parliament elections in Germany are based on proportional representation, while the Bundesrat is not directly elected by the population at all.
Overall, the German electoral system can be understood as an attempt to combine two fundamental principles of democratic representation: personal and regional representation through constituencies on the one hand, and proportional representation of political parties on the other.
