A report by The Reporters’ Collective, in collaboration with data analysts published on September 1, found a staggering number of potential duplicate voters in Bihar. The investigation specifically looked at 39 assembly constituencies and found 1,87,643 cases where individuals with the exact same name and relative’s name were registered twice within the same constituency. The total number of votes from these “dubious cases” across these 39 constituencies adds up to 3.76 lakhs.
The problem of dubious duplicates: categories of duplication
The investigation further broke down the data into more granular categories, highlighting the varying degrees of suspiciousness:
- Identical Entries: In 16,375 cases, the duplicates were “spitting replicas” of each other, with names, relatives’ names, ages, and addresses all matching exactly or being only a few kilometres apart. These are the cases that should have been the easiest for the Election Commission of India (ECI) to detect.
- Near-Perfect Matches: There were 25,862 cases where all credentials—names, relatives’ names, and ages—matched, but the addresses were different. The report suggests that these could have been easily caught by the ECI’s software designed to identify “demographically similar entries.”
- Similar Ages: The most common category of duplication involved 1.02 lakh cases where individuals were registered twice with the same name, parent’s name, and an age difference of up to 5 years. This age similarity makes it difficult for a polling officer to distinguish between the two entries, potentially allowing a person to vote twice. The investigation also found 40,781 cases with a 6–10-year age difference and 45,774 cases with a difference of over 10 years.

The findings directly contradict the ECI’s claim that it had already removed more than seven lakh duplicate voters, representing 0.89% of electors, before publishing the draft rolls. The sheer number of remaining duplicates suggests that the deduplication process was not as thorough as the ECI had stated. The report also highlights that the ECI made the draft electoral rolls non-machine-readable, complicating large-scale data analysis by external parties.
Anomalies in voter deletions
On September 1, a separate analysis by The Hindu focused on the 65 lakh voters deleted from the draft electoral roll and revealed several distinct categories of anomalies. The patterns uncovered raise concerns about potential disenfranchisement, particularly of women and young voters, and the accuracy of the reasons for deletion.
Suspicious deletion patterns
The analysis identified eight specific patterns that defy demographic norms:
- Young Deaths: 80 assembly parts (polling stations) showed an unusually high proportion of young deaths. In these areas, more than half of the deceased voters were under the age of 50. For example, at one polling station in Bhagalpur, 50 out of 58 total deaths were of individuals under 50.
- Gender Bias: In 127 parts, there was a high gender bias in deletions, with women making up 80% or more of all deletions. This pattern suggests the potential disenfranchisement of women voters, particularly in areas with significant minority populations.
- Abnormally High Deletion Rates: 1,985 parts had more than 200 deletions each. In one part in Gopalganj, 641 voters were deleted, with the majority marked as “shifted.”
- Excessive Deaths: 412 parts reported more than 100 deaths each, a number that is demographically improbable.
- High Death Proportions: A staggering 7,216 parts reported that over 75% of their deletions were due to deaths. In some cases, like at a polling station in Bhagalpur, 99.4% of deletions were attributed to death.
- 100% Death-Based Deletions: 973 parts reported that all deletions were solely due to death, a statistically impossible scenario.
- Mass “Absent” Classifications: 5,084 stations had more than 50 voters marked as “absent.” In one case in Gopalganj, 457 voters were classified as absent.
- Suspicious Women “Shifts”: 663 parts showed a pattern where at least 60 voters were marked as “shifted,” with women comprising 75% or more of those cases. In three parts in Gopalganj, 100% of the shifted voters were women.

The geographic concentration of these anomalies in border districts and areas with significant minority populations is also noted. The high proportion of deleted young women voters, particularly those marked as “shifted,” raises questions about whether these are cases of marriage migration that were not properly re-registered.
The narratives and numbers
The two reports, while distinct in their focus, paint a similar picture of a flawed electoral roll revision process. They highlight a significant gap between the ECI’s stated claims of a “purified” list and the ground reality revealed by data analysis. The ECI has, in its social media statements, not denied the facts presented but has questioned the methodology, calling it “data mining” and arguing that such patterns do not conclusively prove duplication without on-the-ground verification.
However, the findings have been also endorsed by opposition political parties and activists. The Vote for Democracy expert, Dr. Pyara Lal Garg, for instance, extrapolated the findings of The Reporters’ Collective to estimate the total number of fake voters across all 243 constituencies in Bihar to be over 11.7 lakhs. Similarly, the Congress party has claimed to have submitted 89 lakh complaints of irregularities.
Another day, another “Voter Fraud”: Congress
Reacting to the Reporters’ Collective findings, Congress MP and General Secretary Randeep Singh Surjewala criticised the ECI. Taking to X (formerly Twitter), he wrote, “Another day – another ‘Voter Fraud’! 📍Now, 1,88,000 (1.88 Lakh) ‘Dubious Double Voters’ exposed in Bihar. 📍No day passes before ‘Vote Chori’ isn’t exposed in Bihar
Another day – another “Voter Fraud” !
📍Now, 1,88,000 (1.88 Lakh) “Dubious Double Voters” exposed in Bihar.

TMC MP Sagarika Ghosh also slammed the silence of mainstream media and the inaction of the Election Commission. She posted on X that “Mainstream Godi media may blank out the Opposition’s #VoterAdhikarYatra but EVERY DAY brings out new exposes by non-legacy media of MASSIVE vote manipulation. Time for the Kumbhakarna called @ECISVEEP to wake up. Aisa ‘SIR’ nahi chalega, sirs! #SIR”

However, the ECI has maintained that the draft roll is subject to continuous scrutiny and that individuals and political parties have the opportunity to file claims and objections. The reports highlight the difficulty in doing so, especially with the rolls being non-machine-readable. The Supreme Court has also intervened, with the ECI assuring the court that claims and objections can be filed even after the official deadline, extending the window for voters to rectify their details.
Moreover, the investigations reveal the critical need for transparency and a robust, verifiable process for electoral roll revision. While the ECI has the ultimate authority to validate these cases, the sheer volume of these dubious entries and deletions suggests that the current system has significant shortcomings that could impact the outcome of upcoming elections.
