Tamil Nadu, a state in southern India, is administratively divided into districts that serve as the primary sub‑state units for governance, planning and public administration. Each district contains smaller units such as revenue divisions, taluks, blocks and municipalities. Districts are important for implementing government schemes, maintaining law and order and collecting local statistics.
Administration and characteristics
Each district is typically headed by a District Collector (also called District Magistrate), an officer responsible for revenue collection, development coordination and disaster management. Districts vary widely in geography and economy: some, like Chennai and Coimbatore, are highly urban and industrialized, while others include large agricultural tracts, forested or hilly terrain such as the Nilgiris.
History and development
The boundaries and number of districts in Tamil Nadu have changed repeatedly since British colonial times and after Indian independence. New districts are usually created by dividing existing ones to improve administrative efficiency and bring government services closer to citizens. The process has continued into the 21st century, producing several new districts in recent decades.

Uses and notable facts
Districts provide the framework for local administration, elections to state and national legislatures, and the delivery of education, health and welfare services. They are also used in statistical reporting and development planning. Because boundaries can change, official government sources remain the best place to confirm the current set of districts and their administrative centers.
