ABSTRACT
The actual use of the word ‘basin’, with its undoubted hydrographical references, leads to understand that one is referring to a territorial space in which a certain confluence or collecting is realised of the substance concerned. Interpretative definition of the work basin presupposes as given the places of supply and the places of demand for labour. Such lesser accessibility -as is known - means greater transport costs, in the unit of time that, for biological reasons, conditions the provision of labour, that is, the living day. The other one among the requisites indicated that of environmental quality, will be ensured, and there is assigned with discretion to each urban system a quantity of natural goods that is sufficient to satisfy - on the basis of predetermined standards - the needs of the given population. The labour basin is identified in an integrated basin of urban and social services and in a traffic basin.
