Brazil is divided into 5,570 municipalities, which are the smallest administrative units in the country. Each municipality has its own government, responsible for local services such as education, health, and infrastructure. They vary widely in size, population, and economic activity, ranging from large cities like São Paulo to small rural towns. Municipalities are essential for implementing federal and state policies at the local level. They are governed by elected officials, including a mayor and a city council, who make decisions on local laws and budgets. This structure allows for tailored governance that addresses the unique needs of each community.
