Verified release 2.0.0 · reviewed 29 July 2026
This report establishes four descriptive facts from official Election Commission of India records: the 2026 party seat result, party vote share, statewide turnout history from 2011–2026, and election-administration metadata. It does not infer voter demographics or claim that campaign activity caused the result.
As reported in the ECI party-wise result.
17,226,209 votes in the ECI vote-share table.
11,929,144 votes.
10,462,146 votes.
Verified 2026 results
| Measure | TVK | DMK | ADMK | Validation |
|---|---|---|---|---|
| Seats won | 108 | 59 | 47 | All dataset rows sum to 234 constituencies. |
| Vote share | 34.92% | 24.19% | 21.21% | Source shares sum to 100.01% because ECI displays rounded percentages. |
| Votes | 17,226,209 | 11,929,144 | 10,462,146 | All vote rows sum to 49,324,121. |
The remaining seat and vote-share rows are preserved in the downloadable files. “Other” in the vote-share configuration is an ECI aggregate; this report does not redistribute it among parties or independent candidates.
Turnout series and its limits
| Election year | Statewide turnout | Status |
|---|---|---|
| 2011 | 78.29% | Historical ECI figure |
| 2016 | 74.81% | Historical ECI figure |
| 2021 | 73.63% | Historical ECI figure |
| 2026 | 84.69% | Provisional close-of-poll participation; excludes postal ballots and had 6,411 polling stations pending. |
A comparison across years is descriptive only. The 2026 number has a different publication status from the historical figures, so it should not be used to calculate a final percentage-point change without retaining that qualifier.

Reproducibility appendix
The release can be reproduced without a proprietary tool or private input. Use the pinned repository revision when you need the exact files reviewed for this report.
- Open the pinned Version 2.0.0 repository and inspect the README, field descriptions, and release notes.
- Download the four CSV files or select the matching configuration with the Hugging Face
datasetslibrary. - Check that seats sum to 234 and vote counts sum to 49,324,121. Do not force rounded vote-share values to equal exactly 100%.
- Filter the turnout file to 2026 and retain the complete status and notes fields whenever the 84.69% value is quoted.
- Follow each row’s source URL back to ECI. Record any later ECI revision separately rather than silently overwriting this release.

Think Politically transcribed the named fields into four separate schemas and added row-level provenance. The release does not join voter-level data, estimate missing demographics, model vote transfer, or attribute the outcome to campaign activity. Separating seats, votes, turnout, and metadata prevents fields with different units and evidentiary status from being treated as one observation.
Release checks confirmed that all four CSV schemas load successfully, every row contains a source URL and retrieval date, seat totals equal 234, and vote totals equal 49,324,121. The displayed vote shares total 100.01% due to source rounding. The four configurations and generated Parquet previews were also checked after publication.
Limitations and responsible use
- This is a descriptive, state-level compilation. It cannot establish why an individual voted or why a party won.
- No demographic, caste, age, gender, media-consumption, or campaign-effect inference is supported.
- The dataset does not contain constituency margins, candidates, youth turnout, booth-organisation quality, or party-specific polling-agent totals.
- The ECI “Other” vote-share row is an aggregate and is not decomposed here.
- The 2026 participation figure is provisional and must travel with its source qualification.
- Election authorities remain the authoritative source. Users should check ECI for corrections made after this release.
Version history and correction record
Version 2.0.0 — 29 July 2026: rebuilt as four source-linked ECI configurations with explicit units, status fields, retrieval dates, and a CC BY 4.0 compilation licence.
Version 1 withdrawn: the earlier release mixed incompatible schemas and included estimated margins, placeholder candidate records, youth-turnout estimates, and booth-organisation claims that were not reproducible from the cited official sources. Those files are retained only in repository history and must not be treated as current data.
The former 85.1% turnout statement is superseded by the ECI’s qualified 84.69% close-of-poll participation figure. This report contains no 85.1% result claim.
