migration centripète

CONT: L'auteur préconise une nouvelle approche afin de comprendre l'accroissement des populations périurbaines. Elle développe un modèle conceptuel qui distingue quatre processus de croissance différents (suburbanisation, contre-urbanisation, rétention démographique et migration centripète), chacun agissant quelque peu différemment sur des sous-groupes particuliers.
OBS: Ne pas confondre «exode rural» avec «exode agricole» qui fait plutôt allusion à l'abandon du métier d'agriculteur.

CONT: ... a clear appreciation of the causes of peri-urban growth can only be obtained from a detailed understanding of the underlying demographic processes that affect population growth. In the case of the peri-urban region it is suggested that four key processes can be identified. These are: suburbanisation, counterurbanisation, population retention and centripetal migration. The roles and interactions between these four processes are the subject of a more detailed study currently in progress (Ford).
CONT: The centripetal migration from the country to the city continues unabated, but now there is an equally powerful centrifugal move of migration from the city to the suburbs.

CONT: O êxodo rural provoca, na maioria das vezes, problemas sociais. Cidades que recebem grande quantidade de migrantes, muitas vezes, não estão preparadas para tal fenômeno. Os empregos não são suficientes e muitos migrantes partem para o mercado de trabalho informal e passam a residir em habitações sem boas condições (favelas, cortiços, etc).
