140th European Congress EXPLICATIVE FACTORS FOR THE DIFFERENCES IN POPULATION AND EMPLOYMENT AMONG THE ARAGONESE TOWNS.

The main objective of this paper is to analyze the determinants of population and employment (and their densities) in the towns of the aragonese region (North-East of Spain). The theoretical models, due to Steinnes and Fisher, and Carlino and Mills, permit simultaneous determination of population and employment (and their densities). These models are applied to the 727 towns of the aragonese region in order to analyze the effects of geographic, economic, demographic and location variables on the distribution of population and employment in the first years of the 90´s. The study of these magnitudes in the aragonese region is interesting for explaining the municipal differences among the three provinces (Huesca, Teruel and Zaragoza) which integrate Aragón. The introduction of variables such as the distance to the capital, the borderland situation or other variables related to the kind of communications, may result useful in the interpretation of these differences. The unequal accumulation of people in urban areas with respect to rural areas an
