The Solomon Islands is divided into 10 provinces, which form the first and primary tier of subnational administration in the country's two-level system. Provinces serve as the main administrative units responsible for delivering local government services, maintaining infrastructure, and implementing national policies at the regional level. Each province has its own assembly and premier, exercising authority over matters such as education, health services, local economic development, and community affairs within their jurisdiction. This provincial structure allows for decentralized governance across the archipelago's widely dispersed island groups, enabling administration that accounts for geographic isolation and distinct local needs. The provincial governments work in coordination with the national government based in Honiara while maintaining significant autonomy in managing their respective territories and populations.
