A mayor is the top executive in a city, municipality or town government. The mayor often oversees many public works departments for their locale, including fire, police, emergency medical and utility services. The mayor is commonly a part of the town council, serving in a leadership position for meetings. The powers afforded to a mayor vary based on the structure of the local government. A mayor may be in a strong-mayor setting, where they have many administrative and legislative responsibilities, or a weak-mayor structure, in which the mayor is on a similar level to other members of the town council.
