A final—and unique—example of electoral system design is the modified Borda Count used in the tiny Pacific country of Nauru. The Borda Count is a preferential electoral system in which electors rank candidates as for the Alternative Vote. It can be used in both single- and multimember districts. There is only one count, there are no eliminations and preferences are simply tallied as ‘fractional votes’: in the modified Borda Count devised by Nauru, a first preference is worth one, a second preference is worth half, a third preference is worth one-third and so on. These are summed and the candidate(s) with the highest total(s) are declared the winners.
