Form 20 is an official statement of votes recorded in a constituency. For booth-level work, it allows researchers to compare candidate vote counts, identify the leading candidate at each polling station and calculate margins. These are foundations, not finished political conclusions.
Start with careful data cleaning: confirm polling-station identifiers, candidate names, totals and the treatment of NOTA. Then calculate each station's winner and winning margin in votes and, where useful, as a share of valid votes. Keep turnout analysis separate: turnout requires elector and votes-polled data that may come from other official records.
Patterns are descriptive. A booth-level result does not disclose how a caste, community or individual voted, and comparisons across elections may be affected by changed boundaries or polling-station arrangements. Useful reporting makes such limitations visible.
Good output: a clean dataset, a documented method, comparable summary tables and a brief explaining what the evidence supports.
