The aim of this paper is to determinate the contribution of economic, demographic and climatologic variables in the Spanish housing market value (both new and second-hand market), with data of the different provinces. Starting from housing dealing prices grouped together by regions, and using regression analysis, we obtain as a result explanatory equations of price with a high determination coefficient. In this work we also estimate other variables such as provincial capital index and inter-provincial dispersal index. This one, uses estimations concerning autonomous regions in order to calculate housing market value in the provinces.
