MayorIn many countries, a mayor is the highest-ranking official in a municipal government such as that of a city or a town. Worldwide, there is a wide variance in local laws and customs regarding the powers and responsibilities of a mayor as well as the means by which a mayor is elected or otherwise mandated. Depending on the system chosen, a mayor may be the chief executive officer of the municipal government, may simply chair a multi-member governing body with little or no independent power, or may play a solely ceremonial role.
MunicipalityA municipality is usually a single administrative division having corporate status and powers of self-government or jurisdiction as granted by national and regional laws to which it is subordinate. The term municipality may also mean the governing body of a given municipality. A municipality is a general-purpose administrative subdivision, as opposed to a special-purpose district. The term is derived from French municipalité and Latin municipalis.
ComuneA comune (koˈmuːne; plural: comuni koˈmuːni) is an administrative division of Italy, roughly equivalent to a township or municipality. It is the third-level administrative division of Italy, after regions (regioni) and provinces (province). The comune can also have the title of città ('city'). Formed praeter legem according to the principles consolidated in medieval municipalities, the comune is provided for by art. 114 of the Constitution of Italy. It can be divided into frazioni, which in turn may have limited power due to special elective assemblies.
CityA city is a human settlement of a notable size. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organizations, and businesses, sometimes benefiting different parties in the process, such as improving the efficiency of goods and service distribution.
