Divisions serve as the highest-tier administrative units in Bangladesh's three-level system of governance, with the country divided into 8 divisions. Established to decentralize administration and improve regional governance, divisions function primarily as coordinating bodies between the national government and lower administrative tiers. Each division is headed by a Divisional Commissioner appointed by the central government, who oversees the implementation of national policies, coordinates inter-district activities, and supervises district administrations within their jurisdiction. Divisions facilitate the delivery of essential public services including law enforcement coordination, revenue collection, disaster management, and development planning. While they possess limited autonomous decision-making authority, divisions play a crucial role in aggregating data, monitoring government programs, and ensuring administrative coherence across their constituent districts and upazilas.
