The rural–urban dichotomy is one of the most debated topics by the scientific community in territorial issues. In addition, many public entities and scientific studies have established the distinctive elements of rural and urban spaces by relating the decline of the rural ones with factors such as aging, low birthrate, the primary sector, unemployment, or poverty, among others. Therefore, the purpose of this paper is to spatially study the current model of territorial organization of Spanish urban and rural municipalities as well as their demographic and socioeconomic characteristics. To this end, GIS (Geographic Information System) tools were used to carry out a spatial autocorrelation (SA) analysis and to identify homogeneous groups of the variables considered. In conclusion, there are different demographic and socioeconomic realities in Spain, an urban one located on the coast with a positive situation and, on the other hand, a regressive reality composed of rural municipalities, among which there are villages whose situation is worrying, mainly located in the north of Spain.
