Milan metropolitan area in the context of "Bergamo"

The functional urban area (FUA), previously known as larger urban zone (LUZ), is a measure of the population and expanse of metropolitan and surrounding areas which may or may not be exclusively urban. It consists of a city and its commuting zone, which is a contiguous area of spatial units that have at least 15% of their employed residents working in the city.

The FUA represents an attempt at a harmonised definition of the metropolitan area. Eurostat's objective was to have an area from which a significant share of the residents commute into the city, a concept known as the "functional urban region." To ensure a good data availability, Eurostat adjusts the FUA boundaries to administrative boundaries that approximate the functional urban area.

Milan (/mɪˈlæn/ mil-AN, US also /mɪˈlɑːn/ mil-AHN, Milanese: [miˈlãː] ; Italian: Milano [miˈlaːno] ) is the regional capital of Lombardy, in northern Italy, and the second-most populous city in Italy, with a population of 1.36 million in 2025. The Metropolitan City of Milan is the largest city in Italy by urban area. Its wider metropolitan area is the largest in Italy, and the fourth-largest in the European Union, with an estimated population of 6.1 million.

Founded around 590 BC by a Celtic tribe, Milan was conquered by the Romans in 222 BC, who Latinized the name of the city into Mediolanum and made it the capital of the Western Roman Empire. In the Late Medieval period, the wealthy Duchy of Milan was one of the greatest forces behind the Renaissance. As a major center of the Italian Enlightenment during the Early modern period, Milan's cultural and political struggle against Austrian domination was crucial in the reunification of the Kingdom of Italy. From the 19th century onwards, Milan led the industrial and financial development of Italy.

The Metropolitan City of Milan (Italian: città metropolitana di Milano; Milanese: cittaa metropolitana de Milan, Lombard: [tʃiˈtaː metrupuliˈtana de miˈlãː]) is a metropolitan city (not to be confused with the metropolitan area) in the Lombardy region of Italy. It is the second most populous metropolitan city in the nation after the Metropolitan City of Rome Capital. Its capital is the city of Milan. It replaced the province of Milan and includes the city of Milan and 132 other comuni (sg.: comune). It was first created by the reform of local authorities (Law 142/1990) and then established by the Law 56/2014. It has been operative since 1 January 2015.

The Metropolitan City of Milan is headed by the Metropolitan Mayor (sindaco metropolitano) and by the Metropolitan Council (consiglio metropolitano). Since June 2016 Giuseppe Sala, as mayor of the capital city, has been the mayor of the Metropolitan City.
