Absolute Majority: More than half (i.e., 50 percent + 1)

Alternative Vote (AV): The same constituency boundaries are used under AV as FPTP and voters elect one person to represent them. Voters rank candidates in order of preference, putting '1' next to their first choice, '2' by their second choice and so on. If a candidate receives a majority of first place votes, he or she would be elected just as under the present system. However if no single candidate gets more than 50% of the vote, the candidate with least number of votes is eliminated and their votes redistributed according to the second preferences. This process is repeated until one candidate gets an absolute majority.

Approval Voting: A system in which voters can vote for as many candidates as they like, or "approve of". For example, if used in the last presidential election, voters could have voted for both Perot and Bush, if they liked both of them. The winner is the one who gets the most votes. Never used in public elections, but is used for some private organizations.

Borda Count: A Weighted System using Choice Voting. For example, if five are to be elected, the first preference gets five points, the second gets four, etc. The highest point-getters are the winners. This is a semi-proportional system, but its proportionality is poorer than Cumulative Voting.

Choice Voting: This system is also called STV (Single Transferable Voting), Preference Voting, Ranked Choice Voting, the Hare system, the Hare/Clark system, PR/STV, and other names. This system is the most common form of PR in English-speaking nations. Despite being based on voting for candidates rather than parties, it allows blocs of like-minded voters to win proportional representation. The voter ranks the candidates in order of preference, and the vote is counted in a manner giving proportional results in a multi-winner contest. Ranking additional candidates has no impact on a higher choice candidate's chance to win. Candidates win by reaching a "victory threshold" that is roughly the number of votes divided by the number of seats. If a candidate has too little support among first choices to win, votes for that candidate are transferred to voters' next choices.

Cumulative Voting: A semi-proportional system of voting in which voters have as many votes as seats elected in their constituency, and can allocate them however they wish--including giving more than one vote to a particular candidate. Generally results in fair minority representation. Since it does not allow for the transferring of votes, voters can and do still easily waste their votes. Cumulative voting is semi-proportional because votes can be "wasted" if a candidate receives more than necessary to win, or if two or more candidates "split" the vote of a particular constituency.

Electoral System: The general name for all the rules concerning elections, i.e., the voting system, boundaries, registration of electors, candidacy, campaign spending, broadcasting, etc.

First-Past-the-Post (FPTP): FPTP is the system currently used to elect Members of Parliament. A voting system based on single-member electorates in which the candidate who wins a simple majority of votes is elected. The candidate who gets the most votes wins, regardless of whether he or she has more than 50% support.

Fractional STV: This form of Choice Voting is recommended for all public elections, and for non-governmental elections when a computer will be used. In older forms of Choice Voting, when a candidate was elected, and had surplus votes, some method had to be chosen to determine which ballots would be transferred and which would stay with the candidate. Sometimes they were chosen randomly, sometimes just the last ballots would be chosen, and there are other methods. With fractional STV, a fraction of each ballot is moved to the next most preferred candidate on each ballot, so there is no randomness involved. This is a pain to do by hand, but fortunately there are computer programs to handle the count, if one wishes to use the fractional method. Note that mathematicians and statisticians have shown that the vast majority of the time that the "random" method will give the same results as the Fractional STV. See also "Simplified STV"

Instant Runoff Voting (IRV): Also known as "alternative vote" and "majority preference" voting. A system used when only one person can be elected, such as a mayor or president. IRV is based on the same "transferable vote" mechanism as choice voting, but is a "winner-take-all" system for electing a single candidate such as president or governor. Voters rank the ballot in order of preference. At first, only the #1 rankings are counted. If no candidate has a majority, then the weakest candidate (the one with the fewest number of votes) is defeated, and all of his/her ballots are transferred to the #2 candidate on each ballot. This process continues until someone has a majority. The system is normally abbreviated as "IRV", but is also sometime abbreviates as "IRO" or "IR". It is also sometimes called Majority Preference Voting (MPV), or Alternative Voting (AV).

Interactive Representation (IR): In this system, elected officials have the same number of votes as the number of people that voted for them. It uses an IRV-like procedure to limit the number of candidates. So, each elected official has a different number of votes. This is a very pure form of PR, but without voting for parties. It is a relatively new concept, and to our knowledge, has never been used in a government election. There are some concerns about whether or not it would be legal in public elections. The group that is promoting IR also advocates some other major systemic reforms. Sometimes used as an abbreviation for the Instant Runoff system.

International Order: The combination of major actors, rules, mechanisms and understandings to manage the co-existence and interdependence of states.

Limited Voting: A semi-proportional system in which each voter has less votes than the total number of open seats. For example, there may be five seats to fill, but each voter has one vote. The top vote getters win. Because majority voters have only vote each, they will still normally control a majority of the elected body, but minorities will be more fairly represented. However, votes can be and commonly are wasted, because there is no system to transfer votes from one candidate to another.

List System: In this most widely used form of PR, the voter votes for one party and its list of candidates to represent them. Party lists of candidates can be either "closed" or "open." A closed list means that parties determine the order of their candidates to be elected, often by primary or caucus. An open list allows voters to determine a party's list of candidates by indicating preferences for individual candidates. If a party wins 30 percent of the vote, its candidates win roughly 30 percent of the seats in the legislature, 10 percent of the vote wins roughly 10 percent of seats, and so on. Nationwide lists are used in some countries, but most have regional lists in smaller constituencies. A minimum share of the votes can be required to earn representation; Germany has a 5 percent threshold.

Majority Government: A government made up of one or more political parties that together have an absolute majority of MPs in the House of Representatives.

Microcosm: The idea that a governing body should be a miniature replica of the society it represents.

Minority Government: A government made up of one or more parties which together do not have an absolute majority of all the seats in the House of Representatives, and which therefore rely on the support of other parties outside the government on votes of confidence and in order to pass legislation.

Mixed Member Proportional(MMP): Increasingly popular around the world, this is a hybrid system in which voters have two votes -- one for their district representative, and one for their favorite party. Usually 50% of the seats are awarded by district, and 50% by the party lists. The overall representation is based on the parties' votes. MMP combines geographic representation and proportional representation of ideological interests. Depending on how party lists are allocated, MMP can be fully proportional or semi-proportional. First used in Germany.

Modified At-Large Systems: An election system that is an alternative to traditional at-large plurality systems. With modified at-large elections, the election is still held at-large, but the use of Choice Voting, Cumulative Voting, or Limited Voting, allows for minority representation.

New International Economic Order: A revision of the international economic system in favor of Third World countries.

Non-Compensatory Mixed Member: These semi-proportional systems have some seats filled from districts and some from party lists, but the overall representation is not determined by the party vote. This means that the bigger parties that win almost all the seats in the districts will be over-represented in government, while the smaller parties will be under-represented.

Normative: Political analysis based on values, commitments and ideas.

One-Party-Dominant System: A party system in which there are political alternatives but a single political party dominates the political process as a result of the overwhelming support of the electorate.

Pairwise: A family of single-winner election methods in which the voters rank the candidates in order of preference, and then each pair of candidates has their own little election to see who wins. For example, if candidates A, B, and C are running, and A beats C, but B beats A and B beats C, then B is the winner. This is the case even if B received the fewest number of #1 votes. In Pairwise, that doesn't matter. Pairwise can get complicated if there is no clear winner (A beats B, B beats C, and C beats A, for example). There are many ways to resolve this, so there are many methods that fit into the Pairwise category.

Parliamentary System: A system in which (a) the head of government is not directly elected, (b) the head of government can be removed by a vote of parliament, and (c) the terms of office are not fixed -- early elections can be called. Should never be confused with PR, which affects how candidates are elected when the people vote. Is the opposite of presidential systems. Note that some systems are neither pure parliamentary or presidential systems. England, Germany, Canada and Switzerland are a few examples of parliamentary systems.

Party List: A form of PR in which voters vote for their favorite party. Each party is awarded seats in proportion to the votes that it receives from the electorate. In Open-List systems, they also vote for their favorite candidates within the party.

Pluralism: The open competition of political interests.

Plurality Election Systems: An election system in which the winners are the ones who receive the most votes, without any transferring or other mechanism to allow for minority representation. One common example is a city council in which there are 5 seats to fill, all voters get five votes, and the candidates with the top five totals win. Plurality systems are horrible in terms of minority representation. Another is the Presidential election -- the candidate who receives the most votes wins each state, even if they don't have majority support. Also sometimes called "At-Large" elections, and District Elections have traditionally been the proposed remedy.

Political Culture: Attitudes, values, beliefs, and orientations that individuals in a society hold regarding their political system.

Political Economy: The study of the involvement by the state in the economy of the nation-state.

Preference Voting: Any sort of voting system in which the voter ranks the ballot in order of preference, such as the Single Transferable Vote, the Instant Runoff, Pairwise, Weighted systems, and Bucklin.

Proportional Representation (PR): Proportional representation is the term used to describe any electoral system that ensures that the number of seats each party gets is roughly the same as their share of the vote. The main three types of PR are "MMP", "Choice Voting", and "Party List". There is also a fourth type of PR called Interactive Representation. Is the opposite of "winner take all" or "first past the post" systems. Provides for majority rule, but with fair minority representation. Minimizes the number of wasted votes in each election.

PrV: Sometimes used as an abbreviation for Preference Voting

Representative Democracy: A system of government based on the election of decision-makers by the people.

Residual Powers: Those powers in a federal system of government not explicitly allocated in a constitution.

Responsible Government: A form of government in which the political executive must retain the confidence of a majority of the elected legislature or assembly, and it must resign or call an election if and when it is defeated on a vote of non-confidence.

Runoff System: An electoral system in which additional rounds of balloting are held (with trailing candidates dropped) until a candidate receives a majority of the votes cast.

Semi-Proportional Election: These systems are more proportional than winner-take-all systems, but not as good as PR systems. The three most common kinds of semi-proportional systems are Cumulative Voting, Limited Voting, and non-compensatory mixed member systems.

Simplified STV: A set of rules for counting a Choice Voting election, which is suitable for a hand count for organizations that have up to 500 votes in a contest. The system is still fully proportional and fair, just simpler, not quite as sophisticated as Choice Voting can be. In Simplified STV there are no surplus ballots. The Hare Threshold is used, the Fractional STV system is not used, and duplicate rankings are not allowed. See also "Fractional STV".

Single Transferable Vote (STV): STV is used to elect the Northern Ireland Assembly, as well as for local and European elections in Northern Ireland. It is the system favored by the Electoral Reform Society and is currently being considered by the Scottish Executive for Scottish local elections. With STV constituencies are combined to produce multi-member constituencies each electing several MPs. Parties can field more than one candidate. A single ballot paper is used on which voters rank the candidates in their order of preference - 1,2,3 and so on. From the total votes cast a 'quota' is calculated, which is the minimum number of votes needed for a candidate to be elected. If a candidate has more than the quota of votes the surplus portion of the votes is transferred to the voters' next preferences. Similarly, if a candidate does not have sufficient votes to be elected his or her votes are transferred to the next preferences on the ballot papers.

Single-Member-Plurality (SMP): An electoral system in which the candidate with the most votes wins, even though that win may not represent 51% of the votes.

Single-Party Government: A majority government or a minority government made up of only one political party.

Single Non-Transferable Voting (SNTV): A type of Limited Voting in which each voter gets one vote. Unlike Single Transferable Voting, however, the vote is never transferred, so it is a much less powerful vote.

Weighted Systems: Typically used in sports polls; each voter ranks the ballot, with each level of vote getting a different number of points. Ex) a #1 vote might give that candidate/team 5 points, a #2 vote might be worth 3 points, etc. The points are added up to determine the overall team rankings. Not a bad system when the voters are very knowledgeable and very objective. Not a great system for public elections, because the stakes are so much higher, and people tend to be strong supporters of their favorite candidates.

Winner Take All Systems: Systems in which 50.1% of the voters can win 100% of the representation. These systems, by definition, are un-proportional, the very opposite of Proportional Representation. Examples are plurality elections and runoff elections, the two most common types of election systems used in the United States.
