Aging in aging societies: the transformation of life courses and how we study them

The increase in longevity is not merely stretching life but fundamentally redefining it. Growing old in an aging society becomes both a new individual experience and a collective transformation that challenges the adequacy of traditional life course categories. The Age-It findings call for conceptual renewal to better capture new stages, shifting chronologies, and reconfigured solidarities. Population aging also reshapes the research agenda of gerontologists.
