This volume investigates the critical questions surrounding China's rapidly aging population and the global implications of increasing life expectancy. Yi Zeng, a leading scholar in the field, utilizes the unique Chinese Longitudinal Healthy Longevity Survey (CLHLS) datasets to explore trends in disability compression or expansion over recent decades. The research aims to determine if morbidity compression is achievable alongside a prolonged lifespan, drawing on the unprecedented living experiences of China's elderly.

The book leverages the extensive CLHLS datasets to address fundamental questions about aging and health. Its focus on China's unique demographic situation provides a valuable case study for global gerontology. The research is positioned to inform discussions on health policy and the future of elderly care worldwide. The analysis of disability trends and their relationship with increasing life expectancy offers critical insights for researchers and policymakers alike.
