Patna, 30th Oct: A constituency-wise analysis of Bihar’s Special Intensive Revision (SIR) data as of September 30, 2025, has revealed a 4.88 per cent drop in registered voters compared to the rolls published on January 1, 2025, according to data examined by M76 Analytics.
Using advanced Artificial Intelligence tools, the analytics team processed nearly 90,000 scanned voter block documents across 243 Assembly constituencies to ensure a detailed comparison. On average, each Assembly segment recorded 15,809 fewer voters than in January.
However, the reduction varies across regions — with the sharpest declines in Seemanchal and Bhojpur, while Magadh recorded the least reduction. The Seemanchal belt, where RJD+ and NDA were closely matched in 2020, also saw AIMIM securing 11% of the vote then. Bhojpur, with a 5.56% reduction, was previously an RJD+ stronghold with a seven-point lead over NDA.
Regions such as Anga Pradesh, Mithilanchal, and Tirhut continue to show a historical advantage for the NDA, while Magadh remains a base for RJD+.
The analysis indicates that voter reduction is widespread, cutting across party strongholds. This suggests that the SIR exercise has not disproportionately affected any single political alliance. Still, data shows that 107 Assembly seats fall into categories where the voter reduction exceeds 7.27%, and average victory margins in 2020 were within 11.74%, implying potential shifts in election outcomes.
The real impact of the revision on the 2025 Assembly elections will become evident only after the votes are counted. For now, the figures point toward a reshaped electoral landscape, particularly in regions like Seemanchal and Bhojpur, where voter reductions are highest.
