Evolution des 'living arrangements' des personnes âgées en Belgique et son impact sur la mortalité

Résumé:
Beside age and sex, the living arrangements, with whom a person live, and marital status are largely used to explain the variation of mortality risks for the older adults. Trends in family and household composition have been in interest of demographers but less is known about trends in living arrangements of elderly population and its possible impact on mortality. These trends are associated with steadily improving longevity in the context of population ageing but also with the impact of the second demographic transition characterised by increasing individualisation in demographic behaviour. Studies suggest that not only distribution of living arrangements is affected by the mortality improvements but also that different living arrangements have specific association with mortality risks. This raises a question if and how trends in living arrangements of the elderly could be reflected in mortality improvement. More precisely we intend to check (i) how changes in the structure of the older adults by living arrangements could impact the improvement in longevity and (ii) if the change observed in the association between specific living arrangements and mortality risks could also impact the change in mortality. As some living arrangements are more favourable for survival in old ages than others, some observed relative changes in the distribution of older people by living arrangements might favour or reduce the improvement in mortality. Moreover, the convergence in the association between living arrangements and mortality risks and the smaller variation of mortality risks between living arrangements in advanced ages could counter-balance this effect.
