Electoral systems

Electoral systems refer to the detailed constitutional arrangements and voting systems which convert the vote into a determination of which individuals and political parties are elected to positions of power.

The first step is to tally the votes, for which various different vote counting systems and ballot types are used. Voting systems then determine the result on the basis of the tally. Most systems can be categorized as either proportional or majoritarian. Among the former are party-list proportional representation and additional member system. Among the latter are First Past the Post (FPP) (relative majority) and absolute majority. Many countries have growing electoral reform movements, which advocate systems such as approval voting, single transferable vote, instant runoff voting or a Condorcet method; these methods are also gaining popularity for lesser elections in some countries where more important elections still use more traditional counting methods.

While openness and accountability are usually considered cornerstones of a democratic system, the act of casting a vote and the content of a voter's ballot are usually an important exception. The secret ballot is a relatively modern development, but it is now considered crucial in most free and fair elections, as it limits the effectiveness of intimidation.
