Data-driven analysis of the 2024 Tamil Nadu Lok Sabha election results, covering competitiveness, candidate performance, and voter behaviour.
The victory margin is the difference in votes between the winning candidate and the runner-up. A constituency with a margin under 5,000 votes is considered closely fought. The average margin in Tamil Nadu 2024 was 222,255 votes.
The 10 parliamentary constituencies decided by the narrowest margins.
| Constituency | Winner | Party | Margin |
|---|
Candidates receiving less than one-sixth (16.67%) of valid votes forfeit their security deposit. A high forfeiture rate indicates a party fielded candidates in constituencies with little voter support.
NOTA (None of the Above) allows voters to reject all candidates. When NOTA votes exceed the victory margin, it signals significant voter dissatisfaction.
| Constituency | NOTA Votes | Win Margin | NOTA > Margin? |
