Companies: number of local units per sector of activity and neighborhood

The dataset contains the number of local units (ULs) present in the territory of the Municipality of Milan and their employees, classified by code Ateco 2007 UL (5 digits) and NIL. NOTE 1: Nil = Nucleus of Local Identity, the NILs are 88 and correspond to the neighborhoods. NOTE 2: the local unit is the physical place where the undertaking carries out its business, so it can coincide with the undertaking or part of it. (Some examples: Agency, bar, storage, shop, laboratory, warehouse, professional studio, office, clinic, hotel...). NOTE 3: for some ULs (approximately 2 %) the data on the NIL is not available, due to the address not present or not attached to the toponym archive. For the latter case, the coupling is under verification/completion. The coupling is being completed. NOTE 4: data on employment is calculated as a unit of work. In this regard, it is recalled that full-time work units (FWUs) may refer to work performed in the year by a full-time worker, or to the equivalent amount of work performed by part-time workers or by workers who work twice (e.g. two 50 % part-time workers appear as 1 work unit). The unit of work is therefore not linked to the individual natural person, but refers conventionally to a quantity of standard full-time work defined by national contracts. This explains the presence of values with decimal digits. Source: Asia (Active Enterprise Statistical Archive, 2010)
