As the Election Commission of India (EC) conducts the Special Summary Revision (SIR) of electoral rolls across 12 states and union territories, the crucial role of Booth Level Officers (BLOs) has come into focus. Tasked with verifying, updating, and digitising voter details, BLOs are the frontline workers who ensure that every eligible voter is accounted for and no one is left out of the electoral process.

Each BLO is responsible for one booth within an assembly constituency.

Across India, a typical booth covers around 1,000 voters, generally drawn from about 300 households. The size of a booth can vary depending on population density, urbanisation, and geographical spread. Political parties and election officials often rely on these estimates for planning outreach and field operations.
