The 108 members of the Northern Ireland Assembly are elected from 18 constituencies (US = districts) each returning 6 members. There are 8 different parties represented in that Assembly plus 3 other individual members. The smallest party that gained representation had only 1.6% of the FIRST preference votes overall, but won 2 seats (1.85%). Obviously they concentrated their support into the most winnable constituencies. In one constituency the party had only 4.8% of the FIRST preferences, while in the other they had 9.6% of the FIRST preferences. In both constituencies the quota ("effective threshold") was 14.29% of the total vote. These two successful NIWC candidates won their quotas through the transfers of votes from other elected and excluded candidates. So you have to be very careful about interpreting the effective threshold and first preference votes. Six-member constituencies with STV-PR can give excellent representation of the voters, ie give most of the voters an elected member for whom they voted. But larger constituencies need be no problem. When STV-PR was used to elect the Scottish Education Authorities in the 1920s, the district magnitudes varied from 3 to 10. There were 5 districts with ten members, 14 with nine members, 11 with eight members and 25 with seven members. For a detailed analysis see Appendix 3 in Fairshare's submission to the Scottish Executive's consultation on its White Paper.

If I were confronted with the choice of ONLY FPTP or closed list party list, I too would opt for the party list PR. That is the choice that faced us for our EU Parliament elections, so we took the closed party list PR. Of course, we wanted STV-PR, or at least open list party list, but the government would accept neither. > Of course manageability is relative.

The Northern Ireland Assembly hand count of paper ballots takes one-and-a-half days, and that includes most of the first morning spent in reconciliation of the polling clerks' returns. In Ireland both Houses of the Parliament are elected by STV-PR, and in the 2002 Dail (Lower House) election, an electronic voting system was used for the first time in three constituencies. That trial was highly successful, but computer-only elections are not (yet) legally acceptable for public elections in the UK.
