Electoral Reform Society (ERS) Data (00007)

This dataset contains the results of 86 separate elections of various elections held by non-profit organizations, trade unions, and professional organizations. They were originally donated by Nicolaus Tideman who secured NSF funding to have the ballots tabulated. The ballots are from elections held under various voting rules requiring incomplete strict orders. The tabulated results were initially collected by the Electoral Reform Society in the UK in order to support the adoption of STV and other range voting methods.

The files contain vote records with a maximum of 29 candidates and as few as 3; the number of voters ranges from 9 to 3419. The toc files have all unranked candidates tied, at the end of the order. Additionally, some of these are complete sets of ballots from the given elections and some are random samples from the set of all ballots.
