Project description:

It has long been recognized that the demographics of modern societies are undergoing a fundamental change, with people living longer lives. This has immediate implications for economy and labour force dynamics, as well as the social welfare system. Increasing efforts are being made to improve our understanding of this new phenomenon. As the population, by definition, is a mixture of very heterogeneous entities, it is crucial to characterise the varying experiences of aging in order to understand the needs of individuals and to quantify the impacts of any future policy changes.

Well-designed longitudinal surveys on a national level offer meaningful resources for studying the population trend of the aging process. Longitudinal data analysis is a fundamental tool to understand changes over time, especially, in the context of studying the aging process. The difficulty with working with survey response data is that the aging process is not something that can be measured directly, and we need a careful consideration for modelling and analysis.

Although there are several relevant measurements available related to the aging phenomenon (for instance epigenetic clocks defining the notion of ‘biological age’, or frailty indices), it is difficult or impossible to define what is meant by healthy aging or frailty in general. Aging is a complex process that affects not only the physical and mental but also the emotional well-being of individuals, and these aspects are closely linked. Working at individual level has been made possible thanks to relevant databases available to researches and high dimensional statistical analysis. To deepen our understanding of the factors constituting aging, we require more advanced statistical methodology tofor account for the co-variation and inter-relationships among these factors, of every type (medical, socio-economic, …).

In addition, most studies have focused on the mean process of a single population. Given the nature of the progress each society has made, it is likely that a similar change could occur in different groups of populations in a delayed or transformed time scale. We are interested in capturing such variations of the aging process with the aim of identifying a commonality among those changes.

This proposal is part of a larger international project, named ARLES - Aging Risks and their Long-term impact on the Economy and Society, which aims at developing statistical and probabilistic approaches to understand the relation between health (in broad sense, including socio-economic environment) and aging, looking for indicators to quantify the state of health of aged individuals and relate it to their longevity.
