Detailed Insights
Bihar’s 38 districts serve as grassroots operational units for state administration. The nine divisions—such as Patna, Munger, and Darbhanga—cluster districts for more efficient oversight. A District Magistrate, supported by the district collector and development officers, ensures seamless implementation of policy, maintenance of public order, and timely revenue collection. The territorial extent of districts ranges from the agriculturally rich plains of West Champaran to the hilly enclaves of Arwal, covering a total area of approximately 84,400 km². Population figures—ranging from 5,838,465 in Patna to 2,811,569 in Araria—highlight the unequal spread of demographic weight across the state.
West Champaran, located in the north‑western corner, is not only the largest by area but also hosts the historic Champaran Satyagraha of Mahatma Gandhi. Sheohar, carved out of Sitamarhi in 1990, is the smallest district and is renowned for high‑yield paddy and maize cultivation.
