Coverage and Updates

Voter registration is compulsory in India, which means that every citizen 18 years of age or older must register to vote. We collect voter data from the Electoral Authority in each of India’s 29 States and 7 Union Territories. We keep and track historical records of more than 1 Billion Indian citizens through address changes, name changes and other updates to voter information.

The data is typically updated on an annual schedule as it becomes available from the State and Union Territories Electoral Authorities. We constantly monitor the data release schedule and acquire, process, and make the updated data available soon thereafter. Data updates are available as either a full database replacement or as a delta update containing changes and additions only. You are notified via automatic process that the newest version of the database is available for download.
