The Representation Index measures the percentage of eligible voters who help elect a candidate; it would be 100.0 if all eligible voters helped elect someone and 0.0 if no voters elected someone. One can determine the Index by multiplying voter turnout by the percentage of votes cast for winning candidates. The Index does not weigh how many choices are available to voters, which is much higher in most democracies with proportional voting systems. Even though voters had far more choices than in the United States, the Index was 76.3 in Germany and over 85.0 in South Africa in 1994 elections.
