Daerahs serve as the primary administrative divisions of Brunei Darussalam, with the country subdivided into four districts: Brunei-Muara, Belait, Tutong, and Temburong. As the first level in Brunei's two-tier administrative structure, daerahs function as the principal units for territorial governance and public administration. Each daerah is overseen by a district officer who reports to the central government and coordinates the delivery of government services, including education, healthcare, and infrastructure maintenance within their jurisdiction. The daerah system facilitates the implementation of national policies at the local level while managing district-specific affairs such as land administration, local development projects, and community welfare programs. This administrative framework enables the central government to maintain effective oversight across the nation's territory while addressing the distinct needs of different geographical areas.
