Collection of enumeration forms for the Special Summary Revision (SIR) of electoral rolls is significantly lower in urban areas compared to rural areas across 12 states and Union Territories. Cities like Lucknow, Kanpur, and Noida have reported less collection, a trend also observed in Patna previously. The SIR, which began November 4, aims to identify and remove illegal migrants by verifying place of birth, following crackdowns on undocumented individuals.
