Single Tranferable Vote
  1. How does it work?
    1. Constituencies return more than one member each
      1. Parties can put forward as many candidates as there are seats to fill in each constituency
        1. Electors vote by ranking candidates in order of preference
          1. Don't have to vote for all
            1. To get elected, the candidate needs to recieve a certain quota
              1. Droop Quota - total number of votes cast/(number of seats to be filled + 1) +1
                1. Example - if 100,000 people voted in a constituency of Northern Ireland the quota would be 100,000/6+1 +1 = 14,281 needed to be elected
                2. Votes are counted by first choice
                  1. Once a candidate has gained the quota, any surplus votes are transferred to second placed candidates and so on
                    1. This is repeated each time a candidate gains enough votes to be elected
                    2. If a candidate recieves insufficient first choice votes and is eliminated, all the votes for that candidate are redistributed to the second-placed candidate on the ballot
            2. Proportional Representation
              1. Advantages
                1. Gives the electorate choice between candidates as well as parties
                  1. Competition between candidates from the same party means candidates can be judged on their own merits and records rather than by party
                    1. Multi-member constituencies encourage power sharing
                      1. Far fewer wasted votes
                        1. Greater diversity among elected representatives
                          1. Results in multi-party system
                          2. Disadvantages
                            1. Degree of proportionality can vary
                              1. Single party government unlikely
                                1. Can be disruptive as it encourages competition amongst members of the same party
                                  1. While voting is straightforward, counting is complex and can take a long time
                                  2. Where's it used?
                                    1. Northern Ireland Assembly
                                      1. Local elections in Northen Ireland and Scotland
