How single transferable vote works
NZ is having local elections. Some of the elections work by single transferable vote. The working of STV are not precisely statistics, but they’re nerdy enough in a vaguely mathematical way to be on topic. And I’ve run the counting of STV elections (for the Monash Association of Students), so I have a pretty good grasp of how it works.
Rather than explain it to you, though, I’m going to outsource to Graeme Edgeler’s nice and accurate explanation.
