Multidimensional comparison of countries’ adaptation to societal aging

This is the authors' abstract. We don't add key points for this paper.

Significance The proportion of older adults in the population is growing rapidly across the globe. This demographic transformation into “aging societies” presents very consequential economic and social risks. Countries vary substantially in the degree to which they have been aging and in their establishment of the policies, supports, and services needed to facilitate the well-being of older persons. Based on a multidimensional definition of a successfully aging society, we present an index that quantifies the degree to which nations are effectively facing the challenge of population aging. This index permits comparisons across countries and facilitates identifications of gaps within countries in adaptation as well as approaches that have been effective in closing such gaps.
