Minorities internal migration in Italy: an analysis based on gravity models

Italians and foreigners internal migration assume different behaviour in terms of intensity, geography, type. The levels of the mobility, the propensity to move in a short or in a long range, the propensity to cluster or to disseminate in the host country represent important differential characteristics between the two population. Actually the foreign population seems as a mosaic made up of minorities showing different propensities. This is the reason why an analysis considering foreign population as a whole could reach biased outcome. In the paper some gravity models applied to migratory movements among the 110 Italian provinces concerning the most consistent minorities groups are used. The Poissonian effects (regarding various typologies of masses and distance) show in a synthetic way the main differences among the minorities mobility. Moreover, the interpretation of these parameters allows an original interpretation of the minorities mobility structure inside Italy: the sign and level of the estimates derived from the gravity model can permit to better illustrate the residential model of the minorities reflecting how different theories in this domain act.
