Indonesia is divided into 34 provinces, which constitute the first and highest tier of subnational administration in the country's two-level system. Provinces serve as autonomous regions led by elected governors who oversee regional governance, economic development, and the coordination of district-level administration below them. Provincial governments maintain authority over matters including regional planning, infrastructure development, education, healthcare, and natural resource management, though certain powers remain with the central government in Jakarta. Each province has its own legislative body (DPRD) that works alongside the governor to enact regional regulations and budgets. The provincial structure allows Indonesia to manage its vast archipelago of over 17,000 islands while accommodating regional diversity and local governance needs across its geographically and culturally varied territory.
