According to Chen, these effects are interconnected with factors including access to effective health care, support systems that enhance function and restrict dependency, and programs assuring financial security and opportunities for older persons to effectively engage in society. “We must move beyond the archaic old-age dependency ratios and metrics, such as GDP, which neglect many of the critical factors that influence societal function,” Chen argued.
Finding Better Metrics for Aging
Gender and socioeconomic differences affect a country's ability to support its older adult population. Specifically, the longevity risk associated with females' longer life expectancy entails different needs between genders in old age. Chen aims to quantify gender differences in the aging experience of Organization for Economic Co-operation and Development (OECD) countries and compare differences in projections of disability and chronic diseases among future cohorts of older adults, including disparities by educational attainment.
In order to gain a more nuanced perspective on aging data, Chen drew data from The Aging Society Index, composed of established and available social and economic measures. The Index provides a quantitative estimate of the degree to which a society is successfully adapting to demographic transformation.
Much of Chen’s time is spent focusing on how to address gender-specific needs when developing policies and programs for aging societies. Chen cites The Network on an Aging Society, which defines a successfully aging society as “one which provides for the general well-being of older adults, is cohesive with minimal tension between generations and major subgroups, productive with opportunities for engagement both within and outside the workforce, and is equitable and secure.” Such society-level characteristics are necessary to understand the difference between successful and unsuccessful policies.
Chen identifies systemic gender differences across critical domains of successful social aging that favor males. Thus, Chen argues, for many wealth or income-based measures, such as security, equity and productivity, males experience an advantage, which suggests room for improving women’s standing in paid work, job opportunities, and retirement income. One aspect where women do have an advantage is life expectancy. However, they tend to live longer in poorer health, reflected in a lower well-being score.
Likewise, the gender disparity in cohesion is significantly driven by differences in co-residence rates, which is attributable to women outliving their spouses. These findings suggest that gender-specific needs should be considered when engineering policies and programs for aging societies.
Varying Rates of Functional Disabilities
Gender is not the only society-level characteristic that Chen investigates in her resarch on aging. In a recent study, published in Asian Development Review, Chen and her co-authors, including AHPP Director and FSI Senior Fellow Karen Eggleston, shed light on the dynamic evolution of the health and functional disparities of the future elderly.
