Rezumat/Abstract. The demographic ageing and the decrease of demographic stability are processes determining important challenges for the economies of developed countries. The description and the analysis of spatial - temporal patterns of demographic structures specific for areas of low urban polarizing becomes a priority for durable, balanced, coherent and integrated development of various categories of disfavoured territories. This article tries to describe spatial and temporal patterns of demographic structures, using an analysis of ESDA type (Exploratory Space Data Analysis) for Romania between the last two people census. Using visualizing methods in GIS and using LISA technique, we detected spatial patterns of demographic structures and we emphasized the existence of some clusters and some trends of spatial polarization. The demographic ageing and implicitly the decrease of the rate of young people in territorial demographic structures, represents the main phenomenon being the basis of social and economic disparities, their increase in low polarized areas of urban systems, emphasizing the relations between social and demographic dynamics and regional economic changes.
