The Institute of Statistics and Cartography of Andalusia (IECA) is now developing a series of projects to introduce information on different socio economic phenomena into the grid as a statistical dissemination standard.
The main objective is the location and characterization of the dwellings for spatial analysis. The aim is to measure and monitor, among other things, targets 11.1 “By 2030, ensure access for all to adequate, safe and a ffordable housing and basic services and upgrade slums” and 11.7 “By 2030, provide universal access to safe, inclusive and accessible, green and public spaces, in particular for women and children, older persons and persons with disabilities” within the gl obal objective 11 “Cities of the ODS of the Agenda 2030 for Sustainable Development”.
The source used is the Cadastre, which is an administrative register for fiscal purposes. It is a statistical census of real estate that contains physical, economic and legal description of rural and urban properties.
Housing is not a defined concept corresponding to a Casdastre unit. However, the structure of the information allows the number of homes in the territory to be counted. To do this it is necessary to carry o ut tasks that allow the construction of a housing unit based on the data Cadastre collects. Different approaches have been taken to estimate the number of dwellings, finding the one that best fits regional reality, through the conjunction of the different attributes & information on building parts and constructions registered in Cadastre data files.
