The objective of this paper is to present an innovate approach on the application of GIS and remote sensing in spatial demographic analysis to assess housing situation in the North Coast of Sao Paulo State. In addition, the most common variables used in social sciences and geosciences, as well as the contribution of integrating these data with spatial analysis techniques for territorial planning is discussed. The housing deficit and inadequacies derived from Census Data were spatialized by ‘weighting areas’ (smaller than municipalities) and had their context evaluated through satellite images. Results showed that the smaller ‘weighting areas’ located near the beach coast have higher house density and lowest proportion of housing deficit. On the other hand, larger ‘weighting areas’, located in the innermost part of the region, have greater proportions of housing deficit. This work showed that remote sensing and GIS techniques are valuable tools, providing more detailed and territorialized information on the house deficits and inadequacies, which can improve government actions towards housing policies.
