Definition

The instant runoff electoral system, also known as ranked-choice voting, is a voting method where voters rank candidates by preference. If no candidate wins a majority of first-preference votes, the candidate with the fewest votes is eliminated, and their votes are redistributed according to the voters' next preferences, continuing until one candidate achieves a majority.

Examples

• Multi-Winner IRV: Minneapolis city council elections
• Proportional IRV: Australian Senate elections
• Single-Winner IRV: San Francisco mayoral elections
