[Internal migration in Italy: an overview of studies in the early 1990s]

The author examines "the content of the studies mentioned in the bibliography in order to [investigate]...both the most recent general tendencies of short and long distance migrations [in Italy]. Economic variables appear to have lost a good deal of their explanatory capacity on behalf of causal factors linked with the ¿life cycle'. Also mentioned are the main conceptual categories used in order to define the consequences of migrations on the spatial distribution of populations: so-called ¿atomistic' settlement models, based on administrative units, are now in competition with the growing importance of ¿functional' models, based on pull areas."
