Ageing Ratio Economics

Meaning

This concept quantifies the fiscal and resource implications stemming from the shift in a population’s age distribution toward older cohorts, particularly focusing on the ratio of non-productive years (dependent life) to healthy, productive years (healthspan). It provides a metric for assessing the sustainability of healthcare and social systems as the prevalence of age-related hormonal decline and chronic disease increases. Understanding this ratio is critical for policymakers and individuals planning for long-term financial and physiological well-being.
