Raioni are the second-level administrative divisions in Ukraine's two-tier system of local governance. The country contains 138 raioni, which function as intermediate units between the national government and local communities. These districts handle a range of administrative responsibilities including education, healthcare facilities, social services, and infrastructure maintenance within their territories. Raioni councils coordinate the implementation of national policies at the regional level while addressing local needs and managing public resources. They serve as an important link in Ukraine's administrative structure, facilitating communication between central authorities and municipalities while providing essential government services to residents across defined geographic areas.
