Gminas are the basic administrative units in Poland, similar to municipalities or communes. There are three types of gminas: urban, rural, and urban-rural. Each gmina is responsible for local governance, including education, infrastructure, and public services, serving as the first level of local government. Poland has over 2,400 gminas, which vary in size and population. They play a crucial role in the country's administrative structure, allowing for local decision-making and community involvement. Gminas are governed by elected councils and mayors, ensuring that residents have a voice in local affairs.
