Districts serve as the principal administrative subdivisions in Sri Lanka, forming the second and final level of the country's territorial organization below the provincial level. The country contains 25 districts, each headed by a District Secretary appointed by the central government. These administrative units coordinate the delivery of government services at the local level, including healthcare, education, agricultural extension programs, and infrastructure development. District offices function as intermediaries between provincial authorities and local divisional secretariats, ensuring policy implementation and resource allocation across their jurisdictions. The districts also serve as the primary units for statistical data collection, electoral administration, and disaster management coordination. While Sri Lanka's provincial councils hold certain devolved powers, districts remain crucial operational divisions for central government administration and public service delivery throughout the island nation.
