Myanmar's first-level administrative divisions consist of 18 regions and states that form the primary tier of governance below the national government. These divisions handle essential administrative functions including regional development planning, local law enforcement, education systems, healthcare services, and infrastructure management. Regions specifically denote areas with predominantly Bamar populations, while states indicate areas with significant ethnic minority populations, though both operate with similar administrative structures and responsibilities. Each division maintains its own legislative body and chief minister, exercising authority over municipal governments and local administrative units at levels 2 and 3. This administrative framework allows for both centralized national policy implementation and regional autonomy in addressing local needs and priorities.
