The responsibilities of a mayor in a city government include overseeing daily operations, implementing policies, and serving as a symbolic leader of the city. Mayors manage the budget, coordinate with other city officials, and represent the city in intergovernmental relations. They are also responsible for public safety, infrastructure, and community services, as well as addressing citizen concerns. Effective mayors must balance constituent needs with strategic development goals, often working to foster economic growth and ensure social equity for all residents.
