Data-driven analysis of the 1998 Bihar 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 Bihar 1998 was 60,163 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? |

The Lok Sabha (House of the People) is the lower house of India's Parliament. Members of Parliament (MPs) are directly elected by voters in their respective parliamentary constituencies through universal adult suffrage.
Bihar is divided into 54 parliamentary constituencies. The constituencies are categorized as: GEN (41 seats), SC (8 seats), ST (5 seats). SC and ST reserved constituencies ensure representation for historically marginalized communities.
India follows the First-Past-The-Post (FPTP) electoral system. The candidate who receives the highest number of votes wins the seat. Elections are conducted by the Election Commission of India (ECI) using Electronic Voting Machines (EVMs) and Voter Verifiable Paper Audit Trail (VVPAT).
