Single Transferable Vote. A voting system based on multi-member electorates, used for district Health Boards and some local government elections. Used for national elections in The Republic of Ireland and Malta. Electors indicate the order of their preference for the candidates by marking on the ballot paper 1, 2, 3 etc. The number of votes cast in an electorate and the number of members to be elected determine the quota of votes a candidate must win to be elected. Once the quota is set, the 1st preference votes are counted; candidates receiving more votes than the quota are declared elected and their surplus votes in excess of the quota are redistributed to other candidates according to voters' 2nd preferences. If the required number of members has not been elected, the lowest polling candidate is eliminated and his or her votes are redistributed to other candidates according to voters' 2nd preferences. The redistribution of surplus votes and of votes from eliminated candidates continues until the required number of candidates is elected. See also: STV material from the local body elections
