Concept:
The Election Commission of India (ECI) ensures the accuracy of electoral rolls through various revision processes.
• Electoral Roll: The list of all citizens eligible to vote in a particular constituency.
• Revision Types: These include Summary Revision and Intensive Revision.
Step 1: Understanding the Revision Process.
Electoral rolls must be updated regularly to include new voters and remove deceased ones.
When the data requires a deep, house-to-house verification beyond the standard annual update, a specific "Special" drive is conducted.
Step 2: Defining the Term.
SIR stands for
Special Intensive Revision.
During an SIR, Booth Level Officers (BLOs) perform a complete physical verification of the electors at their mentioned addresses to ensure 100% accuracy before a major election.
