Bulgaria is divided into 265 municipalities, which serve as the primary administrative units in the country. Each municipality is responsible for local governance, including education, infrastructure, and public services. They vary in size and population, with larger cities like Sofia and Plovdiv being significant urban centers. Municipalities are further grouped into 28 provinces, which help organize regional administration. Each municipality is governed by a mayor and a municipal council, elected by local residents. This structure allows for community participation in decision-making and helps address local needs effectively.
