In Kerala's three districts where voter numbers rose post the Special Intensive Revision (SIR) of electoral rolls, turnout showed a jump in two of them while remaining stagnant in the other.
Kasaragod, Kannur, and Malappuram were the only districts in Kerala where voter numbers increased after SIR. In the rest of the 11 districts, the number of electors recorded a decline.
The number of voters in the draft list in October 2025 was 2,78,50,855, but it dipped to 2,69,53,644 after the SIR exercise, a decline of 8.97 lakh voters.
The highest decline was in Thiruvananthapuram district with 3.21 lakh, followed by Ernakulam with 1.83 lakh and Kottayam with 1.12 lakh.
The highest rise in voters post SIR was in Malappuram district with 2.02 lakh voters, while the increase in Kannur and Kasaragod districts was 47,242 voters and 17,895 voters respectively.
Thursday marked a 4% rise in overall turnout in the state compared to the 2021 assembly elections, a trend largely attributed to the clean-up of electoral rolls as part of the SIR.
The turnout this time was 78.27%, according to the last update of the Election Commission of India (ECI), but it still fell short of the 85% polling target set by the ECI.
Of the 32 constituencies across Malappuram, Kannur, and Kasaragod, where the number of voters rose post SIR, 27 of them recorded a rise in turnout ranging from 1% to 10%.
