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."

"Data on in- and out-migration in Egypt by governorate and on variables believed to interact with migration are examined. The purpose is to identify the dimensions through which the basic demographic phenomenon can be rationally structured. This objective is approached through a general multivariate analysis technique known as canonical correlation analysis....A number of variables believed to act as determinants of migration are used and arbitrarily classified into four groups to represent four distinct migration profiles, namely, sociodemographic, economic, urbanization, and health profiles.... The analysis shows that the economic profile of migration is the most pronounced one of the four profiles examined."

"The paper analyzes some problems related to the census measurement of internal migration according to the three following aspects: The lack of agreement between the proposed objectives and the type of question made; questionnaire design errors and enumeration errors; and inadequate data elaboration." The geographic focus is on Latin America. Problems concerning data on place of birth or place of previous residence and how these can affect the calculation of migration trends are considered.
