Non-healthy aging and crucial role of urban space in active aging

The author explores the demographic coordinates of a de-synchronization process between two distinct waves of ageing: on one hand, the abrupt prolonging of the life expectancy, on the other hand the slower delay of the disability free life expectancy. As a consequence, dementias play a crucial role in the future challenges of the Welfare in the Western countries, both for the increasing rate of their spread and for the social peculiarity of their medical cases. The social management and caring of these gradually and compulsorily "no more active" ageing people makes undeniable the need of a re-design of the urban "espaces de vie', as a main road to a more active aging.
