The Special Intensive Revision (SIR) of voter lists in nine states and three Union Territories is showing significantly lower collection of enumeration forms in urban areas compared to rural areas. Election Commission officials attribute this trend to electors' unavailability due to work commitments and constant migration. Cities like Lucknow, Kanpur, and Noida have reported lower collection rates, a pattern observed in previous exercises. The SIR aims to update electoral rolls and identify illegal migrants.
