Description: The China Longitudinal Survey on Influencing Factors of Health and Aging among Older Adults (formerly named the China Longitudinal Survey on Health and Longevity Influencing Factors among the Elderly) is a longitudinal survey of older adults organized by the Peking University Center for Healthy Aging and Development Studies / National School of Development. The survey covers 23 provinces, autonomous regions, and municipalities directly under the central government across China, with respondents including adults aged 65 and above and their adult children aged 35 to 64. Two types of questionnaires are adopted: one for surviving respondents and the other for family members of deceased elderly individuals.

The questionnaire for surviving respondents covers basic demographics of the elderly and their families, socio-economic background and family structure, income sources and economic status, self-rated health and quality of life, cognitive function, personality and psychological traits, activities of daily living (ADL), lifestyle, long-term care, disease treatment, and medical expense coverage. The questionnaire for family members of deceased elderly individuals collects information such as time of death and cause of death.

The project conducted its baseline survey in 1998, followed by follow-up surveys in 2000, 2002, 2005, 2008–2009, and 2011–2012. The most recent follow-up survey (2011–2012) interviewed 9,765 adults aged 65 and above, and gathered information on 5,642 elderly individuals who died between 2008 and 2012. The 7th follow-up survey was carried out in 2014, and the corresponding data is still being curated.

This survey (1998–2014) is the earliest and longest-running national social science survey in China. Its primary funding institution, the National Natural Science Foundation of China (NSFC), once highlighted and commended this survey research in a one-page article in the "Achievement Review" column of its publicly released annual report.
