American Ranked-Choice Voting Election Tabulations 2004-2024

ARCHIVE contains standardized tabulated results for over 7600 round-level candidate vote counts from 514 American ranked-choice voting elections held between 2004 and 2024. The dataset was created by Yuki Atsusaka using a semi-automated LLM-based procedure to collect and validate results from diverse reporting formats.

Use Cases

• Analyze round-level candidate vote counts to model vote transfer patterns across elimination rounds.
• Study electoral competition using consistent election identifiers to link election metadata with candidate-level information.
• Validate RCV tabulation algorithms by comparing simulated results against the standardized round-level attributes.
• Investigate temporal trends in RCV adoption and outcomes across 514 elections over a 20-year period.

Strengths

• Covers 514 American RCV elections, providing a substantial sample for analysis.
• Standardizes over 7600 round-level candidate vote counts from previously disparate sources.
• Includes multiple data levels: election metadata, round-level attributes, and candidate-level information.
• Spans a 20-year time range from 2004 to 2024, enabling longitudinal study.

Limitations

• The dataset's construction relies on a semi-automated LLM procedure, which may introduce standardization errors not fully validated.
• Limited to American jurisdictions, which may not be representative of RCV implementations in other countries.
• The exact number of columns, rows per table, and file formats are unspecified, complicating immediate technical integration.
