Is mayor of India also known as collector?

No, the mayor of a city in India is not the same as a collector. The mayor is the elected head of a municipal corporation and is responsible for local governance, while a collector, also known as a district magistrate, is an administrative officer appointed by the state government to oversee the administration of a district. The roles and responsibilities of these two positions are distinct, with the mayor focusing on urban management and the collector handling Law and Order, revenue collection, and various administrative functions at the district level.
