In this study, the neoclassic approach in the analysis of the migratory movements is taken into a account as a reference to analize some of the variables that determine the volume of immigration in the Canary Islands. A system of structural equations is used as a method. This is a model of imbalance in that the variables of economic nature have major protagonism that any other variable of environmental nature. The results have implications for the politics of immigration and for future research.
