Tablas de contingencia incompletas y modelos de cuasi independencia aplicados a las corrientes migratorias en Cuba.

Abstract

The objective that intended this work was to carry out an exploration on the evolution of the internal migrations from rural places are analysed in Cuba. For analysing the dynamics of the internal migrations we have produced migration tables based on the National Internal Migration Poll (ENMI). The analysis is accomplished by using "cuasi" independent linear logarithmic models. We use these models, excluding the principal diagonal of the matrix for current migratory, containing the higher part of the population, the non-migrants, so that the adjustment reflects the factors characterizing the migration. The matrix has the information of the residence of the migrant at the moment birth takes place and the place of residence when the poll is conducted, with five different categories and four co-variables. One of the results obtained is that the migrant movement trend is progressive from the rural settlements to the places of higher economic hierarchy, which confirms the results obtained through the use crossed tables method in works based on ENMI. Men migrate less than women, except migrations among rural settlements, where it is similar in both sexes. Young and persons with working links and higher qualification migrate more, specially qualified women.
