The Election Commission's draft electoral roll for West Bengal, released on December 16 as part of the Special Intensive Revision (SIR) process ahead of the 2026 Assembly elections, has revealed surprising patterns in "unmapped" voters – those unable to link their enrolment to the 2002 voter list through self or family references. Contrary to earlier political claims that the revision would primarily target alleged infiltrators in border areas, data shows that districts with significant minority populations along the Bangladesh border have the lowest rates of unmapped voters.
Unmapped voters, numbering around 32 lakh statewide, are not automatically deleted but will receive notices for hearings where they can provide documentation to verify their eligibility. The process involves linking current voters to the baseline 2002 roll, a step intended to eliminate duplicates, deceased entries, and untraceable names.
In minority-heavy border districts, unmapped figures remain remarkably low:
- Murshidabad: 2% (approximately 1.2 lakh voters)
- Malda: 1.9% (about 60,000 voters)
- North Dinajpur: 3.2%
- South Dinajpur: 5.4%
Some assembly segments in these areas report even lower rates, with constituencies like Domkal (0.4%), Hariharpara (0.6%), and Sujapur (0.5%) showing near-perfect mapping.
In contrast, higher unmapped percentages appear in other districts:
- Nadia: 6.1%
- Darjeeling: 9%
These figures highlight a stark regional divide. Analysts attribute the strong mapping in border minority belts to long-established community roots, often backed by historical land records spanning generations. The data has undermined pre-revision propaganda suggesting the SIR would disproportionately exclude Muslim voters suspected of illegal infiltration from Bangladesh. Instead, the lowest unmapped rates occur in Muslim-majority areas, while higher figures emerge in regions with significant Hindu populations, including refugee-descended communities.
The Matua community, a Scheduled Caste group largely comprising Hindu refugees from Bangladesh and their descendants concentrated in Nadia and North 24 Parganas, appears particularly affected. In Matua-stronghold areas like Bongaon subdivision, over 1.3 lakh voters face potential hearings due to mapping issues, with many lacking direct links to the 2002 roll because of post-1971 migration.
Political reactions have been sharp. The Trinamool Congress has called the findings proof that narratives of widespread infiltration were exaggerated, arguing the revision exposes settled communities rather than outsiders. Opposition voices maintain that further scrutiny during hearings could still reveal irregularities.
Overall, the draft roll reduced West Bengal's electorate from 7.66 crore to about 7.08 crore, with 58 lakh names deleted mainly for reasons like death, migration, or duplication. The claims and objections period runs until early 2026, giving affected voters time to respond.
For many voters the immediate consequence is practical: those listed as unmapped must produce documentation or submit claims during the designated hearing period, or risk exclusion from the final roll. The patterns revealed by the December 16 draft will almost certainly feature prominently in political debate in the coming weeks - not least because the SIR’s handling, its transparency and the pace of hearings will shape public confidence ahead of next year’s polls.
How to check: The EC has made the draft rolls available on the voters.eci.gov.in portal, the ECINET app and through local election offices; affected electors can file Forms and seek corrections as per instructions on official portals.
