Odisha, a state on the eastern coast of India, is divided into 30 administrative geographical units called districts. These 30 districts have been placed under three different revenue divisions to streamline their governance. The divisions are Central, North and South with their headquarters at Kataka (Central Division), Sambalpur (Northern Division), Brahmapur (Southern Division) respectively. Odisha has 03 Divisions, 30 Districts, 58 Sub-Divisions, 317 Tahasils and 314 Blocks.

History The administrative geography of Odisha was established through three major historical milestones: the creation of a linguistically separate British province on 1 April 1936 under the Government of India Act 1935, the integration of 25 tributary princely states (Garhjats) between 1948 and 1949, and a state-wide administrative decentralization initiative executed between October 1992 and January 1994.

Divisions

The districts of Odisha have been placed under three different revenue divisions to streamline their governance. The divisions are Central, North and South with their headquarters at Kataka (Central Division), Sambalpur (Northern Division), Brahmapur (Southern Division) respectively. Each division consists of 10 districts, and has as its administrative head a Revenue Divisional Commissioner (RDC), a senior rank officer of Indian Administrative Service. The position of the RDC in the administrative hierarchy is that between that of the district administration and the state secretariat.

Administration The Collector and District Magistrate, an officer of the Indian Administrative Service (IAS), is in charge of revenue collection and the general administration of a district. The Superintendent of Police (SP), an officer of the Indian Police Service (IPS), is responsible for maintaining law and order and managing related policing issues within the district. The 30 districts of Odisha are divided into 58 sub-divisions. These sub-divisions are governed by a Sub-Collector and Sub-Divisional Magistrate. For local governance, the sub-divisions are decentralized into Urban Local Bodies (ULBs) for urban areas and Blocks (Panchayat Samitis) for rural areas. The following table lists the administrative sub-divisions, along with the specific urban local bodies and community development blocks mapped hierarchically inside each sub-division, fully totaling 58 sub-divisions, 143 urban local bodies, and 314 blocks statewide:
