The merger of the remaining villages is expected to add a population of at least 4 lakh to the city, which will necessitate an increase in the number of corporators to 168 in the civic body, if the 2011 census is taken into consideration. If the 2021 census is completed before the 2022 civic polls, then the number of corporators in the PMC may increase further, considering the population increase in the existing city limits.
