Urban Sprawl, Labor Incomes and Real Estate Values

The analysis of the processes of urban growth and sprawl should be conducted taking into account the temporal evolution of a plurality of parameters: economic, demographic and socio-cultural. These factors are so related that the complex territorial system sometimes seems indecipherable. Thus, as the quantitative modeling suggests, the real phenomenon is simplified, identifying a limited number of exogenous variables and researching the effect that these variables generate on the simplersystem, object of the study. The goal is to find the functional relationships that govern the events. In the present study, the temporal evolution of the built in a metropolitan area is investigated, in order to determine the effect that the age of construction and geographical location have on the market value of the property for residential use. Then, correlations are recorded with both the labor or capital income that the population perceives on the territory, and with the spatial distribution of the unemployment rate. The construction of the reference dataset is conducted on the basis of official information provided in Italy by the National Institute of Statistics (ISTAT) and the Property Market Observatory (OMI) of Territorial Agency. Finally, the implementation of Geographic Information Systems (GIS), at the level of Census and OMI units, allows to draw thematic maps, from which comparisonthe results of the study are derived
