An analysis by Kolkata's Sabar Institute reveals that during the first phase of the Special Intensive Revision (SIR) of electoral rolls, ‘Das’ and ‘Singh’ were the top surnames removed. ‘Das’ made up 16.73% and ‘Singh’ 12.11% of names deleted in Kolkata and nearby areas including Behala, Salt Lake, and Newtown. The next highest were ‘Shaw’ at 7.82%, ‘Roy’ 6.24%, and ‘Khatoon’ 5.03%. Other surnames deleted included ‘Yadav’, ‘Begum’, ‘Ram’, ‘Sharma’, ‘Mondal’, and ‘Ghosh.’ Ashin Chakraborty from the Sabar Institute said, “The surname analysis indicates that predominantly non-Bengali surnames have been removed during the first phase of SIR. Overall, male names have been excluded to a much greater extent, suggesting that single male migrants, likely from North Indian states such as Uttar Pradesh and Bihar, have been the most affected during the exercise.” The study covered 17 Assembly constituencies including Bhabanipur and Kolkata Port. In Bhabanipur, where Chief Minister Mamata Banerjee is the MLA, ‘Das’ accounted for 18.81% and ‘Singh’ 13% of deletions, followed by ‘Yadav’ and ‘Roy’. In Kolkata Port, represented by Mayor Firhad Hakim, ‘Singh’ was 13.27% and ‘Khatoon’ 8.41%. Earlier, Sabar Institute noted areas with higher Muslim populations in West Bengal had fewer names removed. Following the first phase, about 58,20,899 voter names were struck off statewide, cutting the total registered voters to 7.08 crore as per the draft rolls published on December 16.
