As of March 2020, almost 10 million voting-age adults live in U.S. jurisdictions that use RCV, or have adopted RCV and plan to implement it for their next round of elections.
Since 2004, when San Francisco first began using RCV to elect municipal offices, there have been 366 RCV elections to 128 offices, across 23 jurisdictions. The graph below depicts the number of contests in each of the 21 jurisdictions that presently use RCV or which plan to implement RCV in their next elections.
Of the 23 jurisdictions presently or imminently using RCV to elect offices, 17 exclusively use single-winner RCV (instant runoff voting), while Cambridge (MA) and Eastpointe (MI) exclusively use multi-winner RCV (single transferable vote); Minneapolis (MN) and Palm Desert (CA) use a combination of single and multi-winner RCV, and Payson (UT) and Vineyard (UT) use a combination of single-winner RCV and a form of RCV called preferential block voting. See the glossary for more information on these methods.
