Sélectivité migratoire des populations selon leur âge et concentrations socio-spatiales

Abstract

Linked to social prospects, the factors of internal migrations modifying local age structures have an important impact on socio-spatial concentrations. There is a strong link between age selection by migrations and socio-spatial concentrations. Student migrations and post-graduate employment are the most effective in this matter. Migrations associated with family process have a lower effect on socio-spatial concentrations, except on a small part of urban peripheries where housing is only composed of individual houses occupied by their owners. The spatial distribution of social groups resulting from these internal migration flows, also influenced by unemployment, particularly that of women, leads to a high spatial inequality of households income.. . The factors of age selection by migrations do not entirely account for socio-spatial concentrations. In fact, districts where age structure is the less modified by migrations have a high percentage of social housing, which is associated with other forms of socio-spatial concentrations in urban areas.
