Single Transferable Vote

A Single Transferable Vote voting system is a very typical electoral reform proposal. When there is a single winner, e.g. a Mayor, it is called instant runoff voting and is covered in a separate article.

basis of other improved schemes

A bioregional multi-member district scheme and other "mixed PR-STV" schemes are based ultimately on STV to elect most members.

All such options should be closely considered by any Citizens Assembly on these questions in any jurisdiction. STV may be a first step to other schemes in which some small percentage of seats may be allocated using MMPR.


STV schemes are robust in practice although, worldwide, only about 2% of all voters worldwide cast their votes in such a system. The competing mixed member proportional representation systems are much more common.

Australia and Ireland are the two most notable developed nations using an STV system.

must be ratified

An electoral reform referendum such as the May 17, 2005 BC referendum is usually required to ratify instituting any such system.
