Detection of areas in risk of exclusion from the accessibility to public services of proximity. The case of the city of Valencia

The analysis of the accessibility to the proximity public services is a way of approaching the study of social sustainability in cities. In this article it is analyzed how the location of the above mentioned services (centers of medical specialities, centers of secondary education and basic social services) helps to improve the quality of life of people. The accessibility has been estimated from the place of residence to the center of supply in the city of Valencia using GIS and information spatially detailed –for each building-. The relationship between this accessibility and a series of socioeconomic variables facilitates the detection of neighborhoods with worse social endowments and allows characterizing these areas according to their socioeconomic structure and population at risk of exclusion, in order to facilitate decision-making for the public intervention.
