Abstract

The use of the gravitational model in the study of flows has a long tradition in the geographic science. This paper analyzes the theoretical basis of the gravitational model based on the concept of spatial interaction. Subsequently, this model is tested by applying it to the study of internal migration between communes of the Los Lagos and Los Ríos Regions in the census periods between 1977 and 2012. It was assumed that migration structures have been rather stable and circumscribed in the different regional spaces. Thus, the reliability of the model, the characterization of barrier effects and the preferential relations in the territory are demonstrated. Finally, a spatial pattern is stablished that focuses on the concentration of flows in regional capitals and where migrations in the last 20 years have been limited to each regional space despite the Los Rios Region belonged to the Los Lagos Region.
